Question 32 • 26-27 - C - RUSD Biology in the Living Earth

Sheela wants to demonstrate the importance of photosynthesis to plants and the other living organisms that eat plants. She models the process of photosynthesis that is specifically involved in the production of sugars. Which process in the light-independent reactions of photosynthesis is she modeling?

Answer
A
the production of carbon dioxide
B
the production of water
C
the production of glucose
D
the production of oxygen

Explanation

The light-independent reactions, also called the Calvin cycle, use carbon dioxide and energy carriers to build sugars. Glucose is a sugar, so modeling its production matches the process described. Oxygen is produced during the light-dependent reactions, not the light-independent reactions.
