Question

What is one role of the stroma in the process of photosynthesis?

A) Storing glucose for later use.
B) Synthesizing ATP.
C) Facilitating the light-dependent reactions.
D) Carbon fixation in the Calvin cycle.

Answer 1

The stroma plays a role in facilitating the light-dependent reactions and carbon fixation in the Calvin cycle.

Step-by-step explanation:

The stroma has a role in the process of photosynthesis by facilitating the light-dependent reactions and carbon fixation in the Calvin cycle.

During the light-dependent reactions, light energy is captured and used to produce ATP and NADPH in the thylakoid membrane. These energy-carrying molecules then travel into the stroma, where the Calvin cycle reactions take place.

In the Calvin cycle, energy derived from ATP and NADPH is used to convert CO₂ into glucose and other carbohydrate molecules. This carbon fixation process occurs in the stroma of chloroplasts.
