Step by step
Solved in 3 steps
- Why is the regeneration of RuBP (ribulose-1,5-biphosphate0 a necessary step in the calvin cycle?What is the significance that the combined absorption spectra of chlorophylls a and b roughly match the action spectrum of photosynthesis? Wouldphotosynthesis be more efficient if their individual absorption spectra coincided exactly?Even though a very few cells in a C4 plant carry out the biosynthetic – Calvinpathway, yet they are highly productive. Can you discuss why?
- Consider the Calvin cycle, and the noncyclic photosynthetic pathway. Why is the cyclic pathway so important?It is believed that the ratio of cyclic photophosphorylation to noncyclicphotophosphorylation changes in response to metabolic demands. Ineach of the following situations, would you expect the ratio to increase,decrease, or remain unchanged?(a) Chloroplasts carrying out both the Calvin cycle and the reduction ofnitrite (NO2-) to ammonia (This process does not require ATP.)(b) Chloroplasts carrying out not only the Calvin cycle but also extensiveactive transport(c) Chloroplasts using both the Calvin cycle and the C4 pathwayWhy is the Calvin -Benson Cycle known as the carbon -fixatiion cycle?
- What is the main final product of the calvin cycle?How many turns of the calvin cycle are needed to produce this product?H218O is added to a suspension of chloroplasts capable of photosynthesis.Where does the label appear when the suspension is exposed to sunlight?It is believed that the ratio of cyclic photophosphorylation to noncyclic photophosphorylation changes in response to metabolic demands. In each of the following situations, would you expect the ratio to increase, decrease, or remain unchanged? (a) Chloroplasts carrying out both the Calvin cycle and the reduction of nitrite (NO2 -) to ammonia (This process does not require ATP.) (b) Chloroplasts carrying out not only the Calvin cycle but also extensive active transport (c) Chloroplasts using both the Calvin cycle and the C4 pathway
- The absorption spectrum of chlorophyll a differs from the actionspectrum of photosynthesis. Explain this observation.Please help to fill out the table of the metabolic pathway of Calvin-Benson CycleWhich of the following is not involved in cyclic cyclic photophosphorylation? Group of answer choices: cytochrome bf complex plastocyanin ferredoxin P680
