Question

Define respiration and explain.

Answer 1

a metabolic process by which an organism obtains energy (in the form of ATP) by oxidizing nutrients and releasing waste products. Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the diffusion and transport of metabolites between the organism and the external environment.

Answer 2

Respiration is taking a breath or the act of breathing. An example of respiration is inhaling and exhaling air.
