30 Which of the following are products of the light reaction

30) Which of the following are products of the light reactions of photosynthesis that are utilized in the Calvin cycle? A) H20 and O2 B) 2 and glucose C) ATP and NADPH D) electrons and H+ E) ADP, Pi, and NADP

Solution

30) Which of the following are products of the light reactions of photosynthesis that are utilized in the calvin cycle

C)ATP and NADPH

The light reactions will provide ATP and NADPH to the Calvin cycle in turn the Calvin cycle will provide ADP, i, and NADP+ to the light reactions. The provided ATP and NADPH is used in the carbon fixation step of the Calvin cycle.

28) What is the primary function of the Calvin cycle?

D) Synthesize simple sugars from carbon dioxide

The primary function of the Calvin cycle is to provide the organic products (glucose, the sugar plants need) to the plants using the products ATP and NADPH from the Light Reactions of photosynthesis.

29) End product of a metabolic pathway inhibits an earlier step in the pathway is known as

C)Feedback inhibition

In cell when a hormone or enzyme gets accumulated to a certain level, it will inhibit the earlier step of its synthesis to balance the amount provided with the amount needed.
