Question

What is the path of a carbon atom during photosynthesis , light dependent and non dependent, and cellular respiration

Answer 1

1. Path of a carbon atom during photosynthesis

During photosynthesis, Carbon in carbon dioxide is taken in by the plant leaf and mixed with water molecules and energy absorbed by the sunlight results into formation glucose for the plant to use.

2. Path of a carbon atom during light-dependent reactions

During light-dependent reactions that takes in the thylakoid membrane, the chlorophyll absorbs energy from sunlight and converts it into chemical energy with the use of water.

3. Path of a carbon atom during light-independent reactions

During light-independent reactions, carbon dioxide (CO₂) enters the leaves through stomata and diffuses through intercellular spaces while reaches the mesophyll cells. In the mesophyll cells, carbon dioxide diffuses into the stroma of the chloroplast.

4. Path of a carbon atom during cellular respiration

In cellular respiration, the six-carbon sugar i.e glucose is broken down into two molecules of a three-carbon molecule called pyruvate.
