What are the overall inputs (substrates andenergy sources) and outputs (products and by products) for thelight-dependent reactions of photosynthesis and thelight-independent reactions ofphotosynthesis? How are the light-capturingand Calvin cycle parts of photosynthesiscoupled? Where do the reactions of thelight-capturing part of photosynthesis takeplace? the Calvin cyclereactions?

What are the reactants and products of each of these two stages?

1. All of the following are correct descriptions of photosynthesis except:

A) The Calvin Cycle is endergonic.

C) Chlorophyll and accessory pigments capture energy from the sun in the form of electrons, which they use to drive the electron transport chains of photosystems I and II.

D) ATP and NADPH generated in the light-dependent reactions are used to power CO2 fixation via the Calvin cycle in the light-independent reactions.

2. In glycolysis and the TCA cycle, glucose is _____ down to CO2; this process _____ lots of ATP and reducing power. In photosynthesis, CO2 is ______ back to sugar by the _______ of lots of ATP and reducing power.

A) reduced; requires; oxidized; production

B) oxidized; requires; reduced; production

C) oxidized; produces; reduced; input

D) reduced; produced; oxidized; input

3. Which description accurately compares cellular respiration and photosynthesis?

A) Photosynthesis uses energy captured from sunlight to power the reduction of carbon dioxide to sugars; cellular respiration oxidizes sugars to yield energy for the cell.

B) The ATP produced via cellular respiration is needed to power the reactions of photosynthesis

C) The pathways of photosynthesis are those of cellular respiration run in reverse.

D) Photosynthesis captures energy from sunlight to oxidize carbon dioxide to sugars; cellular respiration reduces these sugars to yield energy for the cell.
