Problem 48 - Objective Biology for NEET

Question

Match the given below organelles with their function: Column I Column II A. Kreb's cycle - 1\. Stalked particles of mitochondria B. Photorespiration - 2\. Cytoplasm C. Oxidative phosphorylation - 3\. Peroxisomes D. Glycolysis 4\. Inner surface of membrane of mitochondria (a) \(\mathrm{A}-2, \mathrm{~B}-3, \mathrm{C}-4, \mathrm{D}-1\) (b) \(\mathrm{A}-1, \mathrm{~B}-2, \mathrm{C}-3, \mathrm{D}-4\) (c) \(\mathrm{A}-4, \mathrm{~B}-3, \mathrm{C}-1, \mathrm{D}-2\) (d) \(\mathrm{A}-3, \mathrm{~B}-2, \mathrm{C}-4, \mathrm{D}-1\)

Step-by-Step Solution

Answer

The correct option is (c) \(A-4, B-3, C-1, D-2\).

Step 1: Understand Processes and Location

The key is to understand where these processes occur. The Kreb's cycle is a series of chemical reactions that occur in the mitochondria. Oxidative phosphorylation also happens within the mitochondria. Glycolysis happens in the cytoplasm. Lastly, Photorespiration occurs in the peroxisomes.

Step 2: Match Process and Location

Now to the second part of the exercise: Matching these functions to their locations. The Kreb's cycle (A) matches with the 'inner surface of membrane of mitochondria' (4), because the Kreb's cycle happens in the inner matrix of the mitochondria. Photorespiration (B) matches with 'peroxisomes' (3) because it mostly occurs there. The process of Oxidative phosphorylation (C) matches with 'stalked particles of mitochondria' (1) because it occurs in the inner mitochondrial membrane where stalked particles are present. Glycolysis (D) matches with 'cytoplasm' (2) as it takes place there.

Step 3: Choose the Correct Option

Based on the above matching, the correct option is: \(A-4, B-3, C-1, D-2\). Among given options, this corresponds to option (c).
