Assertion: The inner membrane of mitochondria contains systems involving electron transport.
Reason: The mitochondrial matrix contains enzymes of Kreb's cycle.
1 Both (A) and (R) are correct but (R) is not the correct explanation of(A)
2 (A) is correct but (R) is not correct
3 (A) is not correct but (R) is correct
4 Both (A) and (R) are correct and (R) is the correct explanation of(A)
Explanation:
(a) Electron transport system is a series of co-enzymes and cytochromes that takes part in the passage of electrons from a chemical to its ultimate receptor. The mitochondrial matrix contains all the soluble enzymes of the citric acid or Kreb's cycle and those involved in the oxidation of fatty acids.

Assertion: Glycolysis occurs in cytoplasm.
Reason: Enzymes for glycolysis are found in cytoplasm. It is common in aerobic/anaerobic respiration.
1 Both (A) and (R) are correct but (R) is not the correct explanation of(A)
2 (A) is correct but (R) is not correct
3 (A) is not correct but (R) is correct
4 Both (A) and (R) are correct and (R) is the correct explanation of(A)
Explanation:
(d) Glycolysis occurs in cytoplasm as all necessary enzymes are found in it. This process is common in aerobic/anaerobic respiration. In this process, one glucose molecule is converted into 2 molecules of pyruvic acid.

Assertion: Fermentation occurs by incomplete oxidation of glucose.
Reason: Yeast form ethanol &$\text{C}{{\text{O}}_{2}}$ from pyruvic acid.
1 Both (A) and (R) are correct but (R) is not the correct explanation of(A)
2 (A) is correct but (R) is not correct
3 (A) is not correct but (R) is correct
4 Both (A) and (R) are correct and (R) is the correct explanation of(A)
Explanation:
(a) Fermentation refers to the incomplete oxidation of glucose under anaerobic conditions in which pyruvic acid is converted to $\text{C}{{\text{O}}_{2}}$& ethanol. E,g. yeast.
Enzymes involve are pyruvic acid decarboxylase & alcohol dehydrogenase.
