Effects of low NADP+ levels in the non-cyclic light reactions of photosynthesis? (Increase, decrease, or no effect)
Step by step
Solved in 2 steps
- Which of the four stages of aerobic cellular respiration is most similar to the light-dependent reactions of oxygenic photosynthesis? Explain.In cyclic photophosphorylation in photosystem I, ATP is produced, even though water is not split. Explain how the process takes place.Is it reasonable to list standard reduction potentials for the reactions of photosynthesis? Why or why not?
- True or false during the dark reaction of photosynthesis energy in the form of light is absorbed and converted to chemical energy in the form of a TPBriefly explain the light-dependent reactions of photosynthesis: where does this take place, what are the reactants and what is produced?In photosynthesis, contrast the light reactions with the light independent reactions, in terms of goals, inputs, and outputs of each. Spatially where do they take place (which parts of the chloroplast)? (Optional, for further discussion: Could there be light reactions without light-independent reactions, or visa-versa?)
- Both photosynthesis and respiration occur in leaves when they are in the light. If the leaves float, is more O2 being produced by photosynthesis or consumed by respiration?What is the chemical formula for photosynthesis? Discuss why (1) Sunlight and water are required for photosynthesis, and (2) Which molecule is reduced, and which is oxidized. Describe in detail the structure and function of the electron transport chain. Discuss how the light-dependent reactions and the Calvin cycle act synergistically to produce food for plants.Which is a more appropriate name for the second stage of photosynthesis, Light-independent reaction or Carbon dioxide fixation?
- There are two photosystems ( I and II) involved in the light-dependent reactions of photosynthesis. What is the functional difference between these two photosystems?• Describe the differences in color between the leaf which was fully exposed to sunlight and the one which was covered with black paper. • Where do the protons used in the light reactions come from? • What is the significance of light reaction? • What are the products of light reactions that are used in the Calvin cycle? • What are the roles of ATP and NADPH in photosynthesis?When elodea takes in carbon dioxide and goes throgh photosynthesis. Is this light-dependent reaction or is it the Calvin cycle?
