Photosynthesis Essay, Research Paper
Photosynthesis occurs in 3 main stages: energy is captured from sunlight, then
it?s converted into chemical energy and stored in organic molecules.
Photosystems are light harvesting units of the thylakoid membrane. Each
photosystem has four hundred pigment molecules. A photon hits the pigment
molecules and travels through each molecule and then reaches the reaction center
as shown in figure 1-1. The thylakoid membrane has two photosystems, photosystem
1 & 2. The reaction center in photosystem 1 is called P700 because this
pigment is best at absorbing 700 mm light. Photosystem 2?s reaction center is
called P680 because it is best at absorbing 680 mm light. Calvin Cycle The
Calvin cycle begins by incorporating Co2 from the air into molecules in the
chloroplast. This action is called carbon fixation. The next thing it does is
add electrons to the fixed carbon to make it carbohydrate. The power of the
Calvin cycle comes from NADPH. The Calvin cycle also needs energy from ATP,
which is generated by light reactions. This is reaction is called ?dark
reactions? because it does not directly need light to work. So basically all
the Calvin cycle does is make sugar with out light but with help from ATP &
NADPH.

The Basics. Sunlight plays a much larger role in our sustenance than we may expect: all the food we eat and all the fossil fuel we use is a product of photosynthesis, which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems. Photosynthesis is carried out by many different organisms, ranging from plants to bacteria (Figure 1).

C3 And C4 Plants Essay Research Paper
C3 and C4 plants have two things in common, they both are found in hot and very dry areas and they both use photorespiration. However, the difference is the way they react toward water loss which will affect photosynthesis. If a C3 plant starts to transpire rapidly because it is photosynthesizing and the stomata are open, then it will close the stomata, ending photosynthesis.
