The enzyme, decarboxylase, catalyses the following step :
| 1. | conversion of citric acid to cis aconitic acid |
| 2. | fumaric acid to malic acid |
| 3. | oxalosuccinic acid to -ketoglutaric acid |
| 4. | malic acid to oxaloacetic acid |
Which of the following is the connecting link between glycolysis and Kreb's cycle?
| 1. | Acetyl Co-A | 2. | Oxalosuccinic acid |
| 3. | Pyruvic acid | 4. | Citric acid |
Which statement is wrong for Krebs cycle?
| 1. | There are three points in the cycle where is reduced to NADH + |
| 2. | There is one point in the cycle where is reduced to |
| 3. | During conversion of succinyl Co-A to succinic acid, a molecule of GTP is synthesised |
| 4. | The cycle starts with condensation of acetyl group (acetyl Co-A) with pyruvic acid to yield citric acid |
After glycolysis, the fate of glucose in the mitochondrial matrix is
1. oxidation
2. reduction
3. oxidative decarboxylation
4. hydrolysis
The number of substrate-level phosphorylations in one turn of a citric acid cycle is
| 1. | One | 2. | Two |
| 3. | Three | 4. | Four |
| 1. | One | 2. | Two |
| 3. | Three | 4. | Four |
| 1. | α–ketoglutaric acid | 2. | Oxalo succinic acid |
| 3. | Succinic acid | 4. | Fumaric acid |
All enzymes of TCA cycle are located in the mitochondrial matrix except one which is located in inner mitochondrial membranes in eukaryotes and in cytosol in prokaryotes. This enzyme is
| 1. | lactate dehydrogenase |
| 2. | isocitrate dehydrogenase |
| 3. | malate dehydrogenase |
| 4. | succinate dehydrogenase |
