Under which condition would you expect the mitochondrial proton gradient to be highest and therefore ATP synthesis to proceed?
| 1. | pyruvate (present)-oxygen (present)-ATP levels (high) |
| 2. | pyruvate (present)-oxygen (present)-ATP levels (low) |
| 3. | pyruvate (present)-oxygen (absent)-ATP levels (high) |
| 4. | pyruvate (absent)-oxygen (present)-ATP levels (low) |
In the mitochondrial electron transport system, the term Complex III refers to:
1. NADH dehydrogenase
2. Cytochrome c
3. FADH2
4. Cytochrome bc1 complex
Oxidative phosphorylation is
| 1. | formation of ATP by transfer of phosphate group from a substrate to ADP |
| 2. | oxidation of phosphate group in ATP |
| 3. | addition of phosphate group to ATP |
| 4. | formation of ATP by energy release from electrons removed during substrate oxidation. |
Oxidation of FADH2 actually involves except
| 1. | Complex I | 2. | Complex II |
| 3. | Complex III | 4. | Complex IV |
Oxidation of complex NADH involves except
(1) Complex I
(2) Complex II
(3) Complex III
(4) Complex IV
Which of the following complex is involved in the transfer of 4 hydrogen ions across the mitochondrial membrane?
| 1. | Complex I | 2. | Complex II |
| 3. | Complex V | 4. | Complex IV |
Which of the following complex does not allow transfer of Protons across the mitochondrial membrane but transfer of electrones in the inner membrane?
| 1. | Complex II | 2. | Complex III |
| 3. | Complex IV | 4. | Complex I |
Why do we call it oxidative Phosphorylation?
| 1. | Because of the presence of oxygen |
| 2. | Because here proton gradient is maintained by the energy of oxidation and reduction |
| 3. | Because of the presence of ADP and oxygen |
| 4. | Because of the presence of Phosphorylation derived by oxygen |
