Describe the stages of Photosynthesis, what happens at each stage.  How does photophosphorylation fit in?

describe how do chloroplasts perform photosynthesis?

What are the two stages in Photosynthesis called and where in the chloroplast does each stage take place? What happens during each stage, what are the reactants and what are the products?

How many types of pigments are involved in photosynthesis?

As energy passes from blue-absorbing chlorophylls down to red-absorbing chlorophylls, surprisingly, no energy passes from lower energy-absorbing pigments back to higher ones (in other words, the process is irreversible). Why might that be?

Describe how the proton (H+) gradient is used to make ATP what is the overall purpose of photosynthesis? What two molecules bring chemical energy from the light reactions to the next stage of photosynthesis, the Calvin cycle At the end of the Calvin cycle, what molecules have the energy that originally came from light?

1. Define energy and state where living things get the energy they need. 2. What is an autotroph? Give an example. 3. How does photosynthesis change energy? 4. How do heterotrophs obtain food? 5. What are the stages of photosynthesis? Which stage occurs first? 6. Describe the chloroplast and its role in photosynthesis. 7. Summarize what happens during the light reactions of photosynthesis.

Which waves of visible light are not used during photosynthesis?

What are the two stages in photosynthesis?

name out the factors influencing Photosynthesis?
