Photosynthesis and Respiration — Test

Question 14 • 26-27 - C - RUSD Biology in the Living Earth

Which statement correctly compares and contrasts the three stages of cellular respiration that occur in the presence of oxygen?

Answer
A
Each stage produces ATP, but only the third stage occurs in the mitochondria.
B
Each stage occurs in the mitochondria, but only the final stage produces ATP.
C
Each stage occurs in the cytoplasm, but only the final stage produces ATP.
D
Each stage produces ATP, but only the first stage occurs in the cytoplasm.

Explanation

All three stages—glycolysis, the citric acid cycle, and oxidative phosphorylation—produce ATP. Glycolysis takes place in the cytoplasm, while the citric acid cycle and oxidative phosphorylation take place in the mitochondria. Therefore, the statement that only the first stage occurs in the cytoplasm is correct.
