Options

• A - III, B - IV, C - I, D - II

• A - IV, B - III, C - II, D - I

• A - I, B - II, C - III, D - IV

• A - II, B - I, C - IV, D - III

Answer 1

A - II, B - I, C - IV, D - III

Explanation:

List I	List II
A. Citric acid cycle	II. Mitochondrial matrix
B. Glycolysis	I. Cytoplasm
C. Electron transport system	IV. Inner mitochondrial membrane
D. Proton gradient	III. Intermembrane space of mitochondria

Metabolic processes take place in many cellular compartments during cellular respiration. In the cytoplasm, glycolysis converts glucose to pyruvate. Pyruvate undergoes further oxidation in the mitochondrial matrix throughout the citric acid cycle. The inner mitochondrial membrane contains the electron transport mechanism, which creates a proton gradient across it. This gradient, which takes place in the intermembrane gap, drives A-P synthesis.
