The process responsible for energy production in animals is:
Correct answer: C. respiration
- A. photosynthesis
- B. digestion
- C. respiration
- D. circulation
Explanation
Respiration: Respiration is the biochemical process by which cells break down organic molecules, such as glucose, and convert them into energy in the form of ATP (adenosine triphosphate). It occurs in the mitochondria of cells and involves the consumption of oxygen and the release of carbon dioxide. Respiration is the primary process responsible for energy production in animals. Photosynthesis, digestion, and circulation are all important processes in living organisms, but they do not directly produce energy in animals.

About Cellular Respiration
Cellular respiration releases energy from glucose through glycolysis, the link reaction, the Krebs cycle and the electron transport chain, producing ATP. The pathway differs in oxygen availability: aerobic respiration uses oxygen and yields more ATP, while anaerobic respiration produces much less ATP and forms lactic acid in muscles or ethanol and carbon dioxide in yeast.
