Question

Identify the key metabolic process for step I and the key metabolic process for step II and briefly explain how each process promotes the movement of carbon through the cycle. For each process, focus on the role of energy in the movement of carbon.

Answer 1

The key metabolic process for step 1 is photosynthesis and the key metabolic process for step 2 is cell respiration. Step 1 promotes movement of the carbon cycle because the energy in is sunlight and for step 2 the energy out for cell respiration is heat.
