Detailed explanation-1: -cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Detailed explanation-2: -Cellular respiration is a process that occurs in the mitochondria of all organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP).

Detailed explanation-3: -Complete answer: 2)The reason why cellular respiration occurs is the need for energy in both plants and animals. The only difference is that plants undergo photosynthesis and can obtain their energy through solar energy but animals cannot undergo photosynthesis so they are dependent on plants for obtaining energy.

Detailed explanation-4: -Cellular respiration can be defined simply as a series of metabolic processes that take place within a cell. Biochemical energy is harvested from organic substances (e.g. glucose) and then stored in energy-carrying biomolecules (e.g. adenosine triphosphate or ATP) for use in the energy-requiring activities of the cell.

Detailed explanation-5: -While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.
