Question

question 20 1 pts during the light independent reaction or calvin cycle of photosynthesis, which of the following is a necessary reactant needed to make glucose? cellulose carbon dioxide water oxygen

Explanation:

In the Calvin - cycle (light - independent reactions of photosynthesis), carbon dioxide is fixed to make glucose. Carbon dioxide provides the carbon atoms for glucose synthesis. Cellulose is a product of glucose polymerization, water is used in the light - dependent reactions for oxygen production, and oxygen is a by - product of the light - dependent reactions, not a reactant for glucose synthesis in the Calvin cycle.

Answer:

B. carbon dioxide
