In the first reaction of catabolism, _ free the _.
Correct answer: B. Protein, Amino acids
- A. Fatty acids, Polysaccharides
- B. Protein, Amino acids
- C. Lipids, Glucose
- D. None of these options are correct
Explanation
CATABOLISM: It is the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy Catabolism breaks down large molecules (such as polysaccharides, lipids, nucleic acids, and proteins) into smaller units (such as monosaccharides, fatty acids, nucleotides, and amino acids, respectively). Protein breakdown into amino acids. Hence, B is the correct option

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.
