What is correct about the following statements.
a. Glycolysis occurs in the cytoplasm of the cell.
b. Aerobic respiration occurs inside mitochondria.
c. ETS occurs in outer mitochondrial membrane.
d. $C_{51} H_{98} O_{6}$ is tripalmitin
e. R.Q.= volume of O2 evolved/ volume of $C O_{2}$ consumed

Solution

Correct statement

Statement a

Glycolysis occurs in the cytoplasm of the cell.

Elaboration

Glycolysis is the partial oxidation of glucose into pyruvate molecules. This occurs in the cytoplasm of both eukaryotic and prokaryotic cells.

Statement b

Aerobic respiration occurs inside mitochondria.

Elaboration

Glycolysis is the initial step of respiration, which occurs in the cytoplasm. This step is common in both aerobic and anaerobic respiration. Steps like oxidative decarboxylation, Krebs’ cycle and oxidative phosphorylation occurs in aerobic respiration within the mitochondria.

Statement d

$C_{51} H_{98} O_{6}$ is tripalmitin

Elaboration

Tripalmitin is a triglyceride derived from palmitic acid. It has a molecular formula of $C_{51} H_{98} O_{6}$ .

Final answer: (A) a, b and d are correct
