What are the main steps in aerobic respiration? Where does it take place?
Assertion (A): Aerobic respiration in eukaryotes requires oxygen for completion. Reason (R): In eukaryotes, the oxygen-requiring steps take place within the cytoplasm.
Correct answer: C — If assertion is true but reason is false.
NCERT confirms aerobic respiration requires oxygen (Assertion true). However, NCERT states “In eukaryotes these steps take place within the mitochondria and this requires O2.” The Reason falsely places oxygen-requiring steps in cytoplasm instead of mitochondria (false).
