Krebs Cycle
High-Yield Trend
Questions 3 MCQs
All enzymes of the TCA cycle are located in the mitochondrial matrix except one which is located in inner mitochondrial membranes in eukaryotes and in the cytosol in prokaryotes. This enzyme is:
| 1. | lactate dehydrogenase | 2. | isocitrate dehydrogenase |
| 3. | malate dehydrogenase | 4. | succinate dehydrogenase |
Which statement is wrong for Krebs' cycle?
| 1. | There is one point in the cycle where FAD+ is reduced to FADH2 . |
| 2. | During conversion of succinyl CoA to succinic acid, a molecule of GTP is synthesized. |
| 3. | The cycle starts with condensation of acetyl group (acetyl CoA) with pyruvic acid to yield citric acid. |
| 4. | There are three points in the cycle where NAD+ is reduced to NADH + H+. |
1. Succinic acid Malic acid
2. Succinyl-CoA Succinic acid
3. Isocitrate - ketoglutaric acid
4. Malic acid Oxaloacetic acid
Preparing Krebs Cycle for NEET

Topic Frequently Asked Questions
Is Krebs Cycle a high-weightage topic?
You can refer to the priority and consistency badges at the top of this page. High priority topics should be thoroughly revised multiple times before the exam.
Should I memorize the solutions?
No, it is highly recommended to understand the core concept and methodology behind each solution rather than memorizing them, as exact questions are rarely repeated, but the concepts definitely are.
