What is the role of oxygen in photosynthesis and in cellular respiration quizlet?

What roles does oxygen play in photosynthesis and in cellular respiration? product, whereas cellular respiration uses oxygen as a reactant to release energy from food.

What is the role of oxygen in photosynthesis?

Oxygen (O2) is evolved during photosynthetic electron transport when water is split by the oxygen-evolving complex to provide protons and electrons to the chloroplastic electron chain, thereby generating ATP and NADPH—the energy source and reducing power for plant metabolism.

What is the primary role of oxygen in cellular respiration quizlet?

What is the role of oxygen in cellular respiration? Oxygen accepts high-energy electrons after they are stripped from glucose. Cellular respiration accomplishes two major processes: (1) it breaks glucose down into smaller molecules, and (2) it harvests the chemical energy released and stores it in ATP molecules.

What is the role of oxygen in cellular respiration and photosynthesis?

In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
