List the two major processes of photosynthesis and state what occurs in those sets of reactions. We can see anatomical differences between C3 and C4 leaves. Unfortunately for the plant, while these gases are moving between the inside and outside of the leaf, a great deal water is also lost.

Animals and human beings in return breathe out carbon dioxide during the process of cellular respiration. This carbon dioxide is in turn used by the plants to make more food. The rains and accumulated water table provides water to the plants and the sun provides light radiant energy every day.

This process is thus, nothing but a cycle that goes on and on. According to the facts of this phenomenon, this cycle has been going on for almost 3, million years, which is quite a long time.

The process of photosynthesis is the reason why all animals and human beings are alive today. Hence, it is absolutely necessary to help plants, to complete this food-producing process. We can simply follow this by not plucking their leaves and watering them every day. Zinc exposed to ultraviolet light becomes positively charged because light energy forces electrons from the zinc. These electrons can create an electrical current. Sodium, potassium and selenium have critical wavelengths in the visible light range.

The critical wavelength is the maximum wavelength of light visible or invisible that creates a photoelectric effect. The color of the pigment comes from the wavelengths of light reflected in other words, those not absorbed. Chlorophyll , the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects to be detected by our eyes.

Black pigments absorb all of the wavelengths that strike them. Pigments have their own characteristic absorption spectra, the absorption pattern of a given pigment.

Absorption and transmission of different wavelengths of light by a hypothetical pigment. Chlorophyll is a complex molecule. Several modifications of chlorophyll occur among plants and other photosynthetic organisms. All photosynthetic organisms plants, certain protistans, prochlorobacteria, and cyanobacteria have chlorophyll a.

Accessory pigments absorb energy that chlorophyll a does not absorb. Accessory pigments include chlorophyll b also c, d, and e in algae and protistans , xanthophylls, and carotenoids such as beta-carotene. Chlorophyll a absorbs its energy from the Violet-Blue and Reddish orange-Red wavelengths, and little from the intermediate Green-Yellow-Orange wavelengths. Molecular model of chlorophyll. Molecular model of carotene. Carotenoids and chlorophyll b absorb some of the energy in the green wavelength.

Why not so much in the orange and yellow wavelengths? Both chlorophylls also absorb in the orange-red end of the spectrum with longer wavelengths and lower energy. The origins of photosynthetic organisms in the sea may account for this.

Shorter wavelengths with more energy do not penetrate much below 5 meters deep in sea water. The ability to absorb some energy from the longer hence more penetrating wavelengths might have been an advantage to early photosynthetic algae that were not able to be in the upper photic zone of the sea all the time.

The molecular structure of chlorophylls. The action spectrum of photosynthesis is the relative effectiveness of different wavelengths of light at generating electrons. If a pigment absorbs light energy, one of three things will occur. Energy is dissipated as heat. The energy may be emitted immediately as a longer wavelength, a phenomenon known as fluorescence.

Energy may trigger a chemical reaction, as in photosynthesis. Chlorophyll only triggers a chemical reaction when it is associated with proteins embedded in a membrane as in a chloroplast or the membrane infoldings found in photosynthetic prokaryotes such as cyanobacteria and prochlorobacteria.

Absorption spectrum of several plant pigments left and action spectrum of elodea right , a common aquarium plant used in lab experiments about photosynthesis. Images from Purves et al. The structure of the chloroplast and photosynthetic membranes Back to Top The thylakoid is the structural unit of photosynthesis. Only eukaryotes have chloroplasts with a surrounding membrane.

Thylakoids are stacked like pancakes in stacks known collectively as grana. The areas between grana are referred to as stroma. While the mitochondrion has two membrane systems, the chloroplast has three, forming three compartments. Structure of a chloroplast. Stages of Photosynthesis Back to Top Photosynthesis is a two stage process. The first process is the Light Dependent Process Light Reactions , requires the direct energy of light to make energy carrier molecules that are used in the second process.

The Dark Reactions can usually occur in the dark, if the energy carriers from the light process are present. Recent evidence suggests that a major enzyme of the Dark Reaction is indirectly stimulated by light, thus the term Dark Reaction is somewhat of a misnomer.

The Light Reactions occur in the grana and the Dark Reactions take place in the stroma of the chloroplasts. Overview of the two steps in the photosynthesis process. Water is split in the process, releasing oxygen as a by-product of the reaction. The incorporation of carbon dioxide into organic compounds is known as carbon fixation. The energy for this comes from the first phase of the photosynthetic process.

Living systems cannot directly utilize light energy, but can, through a complicated series of reactions, convert it into C-C bond energy that can be released by glycolysis and other metabolic processes. Photosystems are arrangements of chlorophyll and other pigments packed into thylakoids.

Many Prokaryotes have only one photosystem, Photosystem II so numbered because, while it was most likely the first to evolve, it was the second one discovered. Photosystem I uses chlorophyll a, in the form referred to as P Photosystem II uses a form of chlorophyll a known as P Both "active" forms of chlorophyll a function in photosynthesis due to their association with proteins in the thylakoid membrane.

Action of a photosystem. Photophosphorylation is the process of converting energy from a light-excited electron into the pyrophosphate bond of an ADP molecule. This occurs when the electrons from water are excited by the light in the presence of P The energy transfer is similar to the chemiosmotic electron transport occurring in the mitochondria.

Light energy causes the removal of an electron from a molecule of P that is part of Photosystem II. These O-2 ions combine to form the diatomic O2 that is released. The electron is "boosted" to a higher energy state and attached to a primary electron acceptor, which begins a series of redox reactions, passing the electron through a series of electron carriers, eventually attaching it to a molecule in Photosystem I.

Light acts on a molecule of P in Photosystem I, causing an electron to be "boosted" to a still higher potential. The electron is attached to a different primary electron acceptor that is a different molecule from the one associated with Photosystem II. The electron from Photosystem II replaces the excited electron in the P molecule.

This energy is used in Carbon Fixation. Cyclic Electron Flow occurs in some eukaryotes and primitive photosynthetic bacteria. Noncyclic photophosphorylation top and cyclic photophosphorylation bottom. These processes are better known as the light reactions. The above diagrams present the "old" view of photophosphorylation.

We now know where the process occurs in the chloroplast, and can link that to chemiosmotic synthesis of ATP. Chemiosmosis as it operates in photophosphorylation within a chloroplast.

Halobacteria, which grow in extremely salty water, are facultative aerobes, they can grow when oxygen is absent. Purple pigments, known as retinal a pigment also found in the human eye act similar to chlorophyll.

The complex of retinal and membrane proteins is known as bacteriorhodopsin, which generates electrons which establish a proton gradient that powers an ADP-ATP pump, generating ATP from sunlight without chlorophyll. This supports the theory that chemiosmotic processes are universal in their ability to generate ATP. Carbon dioxide enters single-celled and aquatic autotrophs through no specialized structures, diffusing into the cells.

Back to Top Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP , the "fuel" used by all living things. Describe the phenomenon of acid rain, and how photosynthesis relates to acid rain and the carbon cycle.. Describe how the pigments found on thylakoid membranes are organized into photosystems and how they relate to photon light energy. Animals and human beings in return breathe out carbon dioxide during the process of cellular respiration. Carbon dioxide enters single-celled and aquatic autotrophs through no specialized structures, diffusing into the cells. The process of photosynthesis actually becomes possible due to the chlorophyll that is present in plant leaves. Six molecules of carbon dioxide enter the Calvin Cycle, eventually producing one molecule of glucose.

All photosynthetic organisms plants, certain protistans, prochlorobacteria, and cyanobacteria have chlorophyll a. Note that OAA and Malic Acid also have functions in other processes, thus the chemicals would have been present in all plants, leading scientists to hypothesize that C-4 mechanisms evolved several times independently in response to a similar environmental condition, a type of evolution known as convergent evolution. Recent evidence suggests that a major enzyme of the Dark Reaction is indirectly stimulated by light, thus the term Dark Reaction is somewhat of a misnomer.
