Question

Choose the correct answers from the alternatives given :
The pathway of aerobic respiration is completed in the

• A. cytoplasm
• B. mitochondrion
• C. plasma membrane
• D. nucleus

Answer 1

The correct option is B mitochondrion

• Aerobic respiration is the respiration that takes place in the presence of oxygen.
• The process of glycolysis takes place in the cytoplasm of the cell after which 2 molecules of pyruvic acid is formed per molecule of glucose.
• After which the molecule of pyruvic acid is converted to acetyl CoA and then it enters the kerb cycle which takes place in the mitochondrial matrix as all the enzymes that are used for the process of kerb cycle is present in mitochondria.
• Therefore the process of aerobic respiration starts in the cytoplasm and ends in the mitochondria.
• Therefore the correct answer is the 'mitochondrion'.
