One molecule of ATP is composed of
Correct answer: C. guanine, ribose and two phosphate groups
- A. adenine, ribose and three phosphate groups
- B. adenine, deoxyribose and three phosphate groups
- C. guanine, ribose and two phosphate groups
- D. adenine, glucose and three phosphate groups
Explanation
ATP is a nucleotide: the base adenine joined to the sugar ribose and a chain of three phosphates. The sugar is ribose rather than deoxyribose, which is why ATP belongs to the RNA family of nucleotides.

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.
