Solution
The correct option is B Mitochondrion
Mitochondria are called as powerhouse of cell, because they manufacture most of the ATP in a cell during aerobic respiration. Pyruvic acid molecules are metabolised completely inside the
mitochondria in Kreb's cycle and ATP is produced. This production of ATP
is called as oxidative phosphorylation because it involves oxidation of
food, i.e., glucose. This process requires oxygen in the terminal step
of electron transport chain of mitochondria and produces water as a by
product. Carbon dioxide is released at several stages in the Kreb's
cycle. Thus, the enzyme required for the respiratory reaction like
Kreb's cycle and electron transport chain is present in mitochondria.
Thus, the correct answer is option C.
