Which of the following absorb light energy for photosynthesis?
Correct answer: A. ChlorophyII
- A. ChlorophyII
- B. Water molecules
- C. O2
- D. RuBP
Explanation
The answer is A) Chlorophyll.Chlorophyll is a green pigment that is found in chloroplasts, the organelles that are responsible for photosynthesis in plants. Chlorophyll absorbs light energy, which is used to split water molecules and release oxygen. The energy from the light is also used to convert carbon dioxide into glucose.Water molecules, O2, and RuBP do not absorb light energy for photosynthesis. Water molecules are split during the light-dependent reactions of photosynthesis, but they do not absorb light energy themselves. O2 is a byproduct of photosynthesis, and it is not involved in the absorption of light energy. RuBP is a molecule that is used in the Calvin cycle, but it does not absorb light energy.So the only option that absorbs light energy for photosynthesis is chlorophyll.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
