Q. No.The process used in conversion of Pyruvate to Acetyl CoA is
1. Oxidative dehydration
2. Oxidative decarboxylation
3. Oxidative phosphorylation
4. Reductive phosphorylation.
If RQ is 0.6 in a respiratory metabolism, it would mean that
| 1. | Carbohydrates are used as respiratory material |
| 2. | Organic acids are used as respiratory substrate |
| 3. | The oxidation of the respiratory substrate consumed more oxygen than the amount of CO released |
| 4. | The oxidation of respiratory substrate consumed less oxygen than the amount of CO2 released |
In ETS, complex V is
1. ATP synthase
2. NADH dehydrogenase
3. Cytochrome c oxidase
4. Cytochrome bc complex
The first step of decarboxylation in cellular respiration is
| 1. | Conversion of PGAL to DHAP |
| 2. | Conversion of PGAL to PGA |
| 3. | Conversion of Pyruvate to Acetyl CoA |
| 4. | Conversion of BPGA to PGA |
How many molecule of NADH are produced during oxidation of one molecule of Glucose to Acetyl CoA?
