(a)
Interpretation:
The pathway present in given cycle should be identified as whether it is exergonic or endergonic reaction.
Concept Introduction:
Exergonic:
The reaction is considered as exergonic if energy released since the reactants loses its energy making the free energy more negative hence making it spontaneous reaction.
Endergonic:
The reaction is considered as endergonic if it needs more energy which means the activation energy is much higher making the reaction non spontaneous.
(b)
Interpretation:
The source from which energy obtained for endergonic pathway should be identified.
Concept Introduction:
Endergonic:
The reaction is considered as endergonic if it needs more energy means that activation energy is much higher making the reaction non spontaneous.

- Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?arrow_forwardThe Overall Free Energy Change for Photosynthetic NADP+ Reduction What is the overall free energy change (G) for noncyclic photosynthetic electron transport? 4 (700-nm photons) + 4 (680-nm photons) + 2 H2O + 2 NADP+O2 + 2 NADPH + 2H+arrow_forwardWhat is the overall purpose of the light reactions in photosynthesis?arrow_forward
- 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?arrow_forwardIn biochemistry, the exergonic process ofconverting glucose and oxygen to carbon dioxide and water in aerobic metabolism can be considered the reverse of photosynthesis,in which carbon dioxide and water are converted to glucose andoxygen. Do you expect both processes to be exergonic, both endergonic, or one exergonic and one endergonic? Why? Would youexpect both processes to take place in the same way? Why?arrow_forwardIs it reasonable to list standard reduction potentials for the reactions of photosynthesis? Why or why not?arrow_forward
- Write the overall net reaction for photosyynthetic Co2 fixation. (Take into account both light and cark reaction of photosynthesis?)arrow_forward1. A) For the schematic of a chloroplast shown in the image attached, match the major input and output molecules of photosynthesis to the letters shown. Molecules: CO2, H2O, O2, sugar A: B: C: D: B) In the image attached, the light reactions are shown to take place in the thylakoid. Where specifically do these reactions take place? C) Where does the Calvin cycle take place?arrow_forwardHow are the light-capturing and Calvin cycle parts of photosynthesis coupled? How would poisoning the electron transport system associated with the light-capturing reactions of photosynthesis affect the Calvin cycle reactions?arrow_forward
- 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 pathwayarrow_forwardA substantial amount of energy is put into the photosynthetic electron transport to extract electronsf from water and to elevate the energy level of ferredoxin to a very strong reductant. The amount of energy in one NADPH is 218 kJ.mol-1. What is the percentage of this energy conserved in NADPH for the production of one mole of oxygen? What happened to the rest of the energy?arrow_forwardATP is produced by chemiosmosis in photosynthesis". Identify where and how this chemical gradient is formed?how this is driving the ATP synthesis. Mention where the light dependent and light independent reactions of photosynthesis take place along with the functional end product(s) of these two stages. Dark and light reactions of photosynthesis are interconnected, how?arrow_forward
