Discuss some of the advantages to having a cycle that partially replenishes itself. In the Calvin cycle, what would happen to the cycle if there was no carbon dioxide available?

Figure: Light Reactions: Light-dependent reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where the Calvin cycle takes place

Explanation:The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.

The carbon atoms used to build carbohydrate molecules come from carbon dioxide, the gas that we exhale with each breath.

Explanation:

Dark reactions are also referred as "light independent reactions" (since they can occur during day or night) or as "carbon-fixation" (since carbon dioxide is taken from the air and carbon is affixed to compounds in the plant) or as the Calvin Cycle (named for the person who discovered it).

answer; i believe the correct answer to the above question is ( friction)
