Question

Photosynthesis and cellular respiration are often described in two ways: (1) they are chemically opposite; and (2) they have a relationship to each other. Explain what these two statements mean. Be sure to include the specific substances used and released by each process. @misssunshinexxoxo

Answer 1

Photosynthesis is the process of carbon reduction, while respiration is carbon oxidation. Photosynthesis splits water and energizes the electrons from hydrogen. Respiration de-energizes these electrons and returns them to water.

Answer 2

Cellular respiration is the aerobic harvesting of energy from food molecules; the energy-releasing chemical breakdown of food molecules, such as glucose, and the storage of potential energy in a form that cells can use to perform work; involves glycolysis, the citric acid cycle, the electron transport chain, and chemiosmosis.
