Question

Photosynthesis is

• A. Reductive and exergonic
• B. Reductive and catabolic
• C. Reductive, endergonic and catabolic
• D. Reductive, endergonic and anabolic

Answer 1

The correct option is D Reductive, endergonic and anabolic

Photosynthesis is the process by which green plants utilize the energy from sunlight to convert carbon dioxide and water into chemical energy, in the form of carbohydrates such as glucose.
Therefore photosynthesis is anabolic and endergonic. As energy in the form of sunlight is absorbed and converted to chemical energy that is stored in carbohydrates such as glucose.
During photosynthesis, water is oxidised to oxygen and $C{O}_2$ is reduced to carbohydrates. Therefore photosynthesis is also a redox proess.
Hence photosynthesis is anabolic, endergonic and redox process.
