In light of the fact that photosynthesis occurs largely in plant leaves, you should understand the structure of the leaf before you learn how the process works. The process of photosynthesis explained in simple steps: Step 1. The first step in photosynthesis is the absorption of light by chlorophylls that are attached to the proteins in the thylakoids of chloroplasts. A byproduct of photosynthesis is Oxygen, meaning that photosynthesis in plants is the major factory of oxygen on our planet, a factory that keeps us alive. Which product leaves? The PEP carboxylase mediates the conversion of carbon dioxide and PEP to malic acid. 6. The biochemical pathway of CAM photosynthesis begins during night.The stomata of CAM plants are open at night so the formation of malic acid take place in the night and it get accumulated in the cell vacuole and later it breaks down in day. Where do the light reactions occur? If the smartest energy source is one that's abundant, cheap and clean, then plants are a lot smarter than humans.
