Important NEET Questions on Class 11 Chapter 14 Respiration In Plants

1. The biomolecule involved in the respiration-mediated breakdown of fats, carbohydrates and proteins is common (NEET-II 2016)

A. Acetyl CoA

B. Pyruvic Acid

C. Fructose 1,6-bisphosphate

D. Glucose-6-Phosphate

This is not a statement about Kreb’s cycle.

A. There are three points in the cycle where NAD+ is reduced to NADH+H⁺

B. The cycle starts with the condensation of acetyl CoA with pyruvic acid to yield citric acid

During the conversion of succinyl CoA to succinic acid, a molecule of GTP is synthesized.

D. There is one point in the cycle where FAD+ is reduced to FADH2.

Respiration-mediated breakdown of fats, carbohydrates, and proteins commonly produces this metabolite (NEET 2013)

A. Fructose 1,6-bisphosphate

B. Glucose-6-Phosphate

C. Acetyl CoA

D. Pyruvic Acid

The process of releasing energy through the oxidation of a substrate without an external electron acceptor is referred to as ‘anaerobic respiration’ (2010, 2008).

A. Photorespiration

B. Aerobic Respiration

C. Glycolysis

D. Fermentation

The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that adenosine triphosphate (ATP) is formed through the transfer of protons across a membrane, resulting in a proton gradient that is utilized to generate ATP (2008).

A. ADP is exported from the matrix into the intermembrane space.

B. High energy bonds are formed in mitochondrial proteins

C. There is a change in the permeability of the inner mitochondrial membrane towards Adenosine Diphosphate (ADP)

A protein gradient forms across the inner membrane

The overall goal of glycolysis, Kreb’s cycle, and the electron transport system is the formation of ATP (2007).

A. Sugars

B. ATP in Small Stepwise Units

C. ATP in one large oxidation reaction

D. nucleic acids

If the complete oxidation of one mole of glucose to CO2 and H2O yields 686 kcal and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is 12 kcal, then the maximum number of ATP molecules that could be generated from one molecule of glucose is 57.

A. 57

B. 30

C. 2

D. 1

During the oxidative phosphorylation stage of the complete oxidation of glucose, the greatest number of ATP molecules are formed from ADP. (2005)

A. Electron Transport Chain

B. Kreb’s cycle

C. Glycolysis

D. Conversion of Pyruvic Acid to Acetyl CoA

9. In Alcohol Fermentation (2003)

A. Pyruvic acid is the electron acceptor while triose phosphate is the electron donor.

B. Triose Phosphate is the Electron Donor while Acetaldehyde is the Electron Acceptor

C. Oxygen is the electron acceptor

D. There is no electron donor

Answer: Approximately 36-38 ATP molecules are produced by aerobic oxidation of one molecule of glucose (2002).

A. 38

B. 34

C. 4

D. 2
