LIFE SCIENCE

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: -The main function of cellular respiration is to synthesize biochemical energy. Cellular respiration is essential to both eukaryotic and prokaryotic cells because this biochemical energy is produced to fuel many metabolic processes, such as biosynthesis, locomotion, and transportation of molecules across membranes.

Detailed explanation-3: -The cells all rely on the same process to get their energy: cellular respiration, a process that releases energy by combining glucose and oxygen. We can explain cellular respiration-and how animals get energy to move-by answering the four numbered questions on the Three Questions handout: 1.
