The existence of being able to process photosynthesis.

Photosynthesis is a functional and adaptive mechanism which enables plants to make and create their own food with the use of sunlight. Also, water and carbon dioxide, oxygen is then the by product of this process which is beneficial to other organisms especially heterotrophs.

What molecules are required for the Calvin cycle? (3 answers)

Ber [7]

Answer:After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build food in the form of carbohydrate molecules. The carbohydrate molecules made will have a backbone of carbon atoms. Where does the carbon come from? 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.

Explanation:The Interworkings of the Calvin Cycle

In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle. Others call it the Calvin-Benson cycle to include the name of another scientist involved in its discovery (Figure 5.14).

This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
