Light energy is converted into chemical energy through the formation of?
Correct answer: C. ATP and NADPH2
- A. NADPH2
- B. ATP
- C. ATP and NADPH2
- D. RuBP
Explanation
Light energy is converted into chemical energy through the formation of ATP and NADPH. ATP (adenosine triphosphate) is the universal energy currency of cells. It is used to power many cellular processes, including muscle contraction, protein synthesis, and cell signaling. NADPH (nicotinamide adenine dinucleotide phosphate) is a reducing agent that is used to synthesize carbohydrates and other molecules. Both ATP and NADPH are produced during the light-dependent reactions of photosynthesis. The light-dependent reactions occur in the thylakoid membrane of chloroplasts. They involve the absorption of light energy by chlorophyll molecules, which leads to the release of electrons.

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.
