NEET BIOLOGYRespiration in PlantsEasy

Question

Which of these statements is incorrect?

A

Enzymes of the TCA cycle are present in the mitochondrial matrix

B

Glycolysis occurs in the cytosol

C

Glycolysis operates as long as it is supplied with NAD that can pick up hydrogen atoms

D

Oxidative phosphorylation takes place in the outer mitochondrial membrane

Step-by-Step Solution

the Electron Transport System (ETS) and the associated process of oxidative phosphorylation take place in the inner mitochondrial membrane, not the outer membrane. The other statements are correct: the TCA cycle enzymes are located in the mitochondrial matrix, glycolysis occurs in the cytoplasm (cytosol), and NAD+ is required for glycolysis to proceed.

Exam Context & Concepts Covered

This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Respiration in Plants. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
