d) In the presence of sunlight, an electrochemical gradient is generated between two of the spaces within the chloroplast. 1.Describe what happens when a photon of light energy hits a molecule of chlorophyl. 2. What is meant by the term electrochemical gradient? 3.What role does the photosynthetic electron transport chain play in the generation of the electrochemical gradient? 4. Two chemical reactions also contribute to the generation of the electrochemical gradient. What are the reactions, where do they occur, and why do these factors affect the gradient? 5. The electrochemical gradient can be utilised by ATP synthase to generate ATP - explain how the location and structure of ATP synthase enable it to perform this function. e) The light reactions of photosynthesis generate ATP and NADPH for use in the dark reactions (i.e., the Calvin cycle). Why are they needed?

In this question, I'd like you to think about what would happen if we applied an herbicide that prevented plant growth by inhibiting some of the pieces in your diagram above. For example, if we applied an herbicide to our plants and it affected the ability of Photosystem II to work, it would prevent he production of oxygen. Let's say we apply an herbicide to our plants and it affects the function of ATP synthase. What product would be inhibited? Group of answer choices ATP NADPH G3P Oxygen
For each of the statements below, indicate whether they are true or false and then in detail explain why the false statements are incorrect, making reference to the relevant cell processes and/or molecules. A. In cellular respiration the ETC transfers electrons via redox reactions whereas in photosynthesis the ETC transfers electrons using light. B. In cellular respiration the ETC creates a proton gradient with the higher concentration on the outer side of the inner membrane whereas in photosynthesis the ETC creates a proton gradient with the higher concentration on the inner side of the thylakoid membrane. C. In cellular respiration the ETC gradient is used to power ATP production by oxidative phosphorylation whereas in photosynthesis the ETC gradient is used to power ATP production by substrate level phosphorylation.
