Answer: 1. Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.
2. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.
3. Any chemical process that yields energy is known as a catabolic pathway. Cells release the energy in those organic molecules by breaking them down. Through cellular respiration and fermentation, those bonds are broken releasing the potential energy of organic molecules into kinetic energy that cells use to do work.
