Top Ten Things to Know: 1. Plants are autotrophs, meaning that they synthesize their energy from sources other than other organisms. 2. Photosynthesis occurs in the chloroplasts of photo-autotrophs; this organelle is unique to plant cells. 3. The oxygen released as a by-product of photosynthesis comes from the splitting of water: water is oxidized and carbon dioxide 4. A plant’s ability to harness the energy in a photon depends on the specific wavelength of light in that photon: optimal wavelengths 5. Photosynthesis is divided into the light-dependent reactions and the Calvin- Cycle. 6. Light reactions add a phosphate group to ADP in photophosphorylation to

Unformatted text preview: convert light energy to a usable form. 7. All products produced in the light reactions (ATP, NADPH) that are used in the Calvin Cycle, return to the light cycle in a different form (ADP, NADP+) 8. The Calvin Cycle produces sugar using carbon dioxide by doing carbon fixation with the enzyme Rubisco. 9. Carbon dioxide is reduced (electrons are added) to carbohydrates; this cycle uses 9 ATP and 6 NADPH. 10. Photorespiration occurs when Rubisco denatures; to avoid this useless process, plants have evolved....
