Why does oxygen is important for complete oxidation of Glucose?
| 1. | Because it is limited to the terminal stage of the process |
| 2. | Because it drives the whole process by removing hydrogens from the system |
| 3. | It acts as the final hydrogen acceptor not the Electron acceptor |
| 4. | Both B and C |
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 |
The amount of energy which is produced by one molecule of FADH2 and one molecule of NADH?
(1) 2 ATPs, 3 ATPs
(2) 5 ATPs, 3 ATPs
(3) 3 ATPs, 3 ATPs
(4) 3 ATPs, 2 ATPs
Which of the following gradient is observed in ETS?
(1) Chemical
(2) Electrical
(3) Osmotic
(4) Electrochemical
Which of the following statements is incorrect?
| 1. | Glucose is the flavoured substrate for respiration |
| 2. | All carbohydrates are usually first converted into glucose before they are used for respiration |
| 3. | Other respiratory substrates are also respired but they do not enter the respiratory pathway at very first step |
| 4. | Fats directly enter the respiratory pathway |
Glycerol and Fatty acids are the result of breaking down of Fats:
(1) Fatty acids enter at the step of formation of BPGA
(2) Fatty acids enter as acetyl CoA
(3) Fatty acids enter as PGAL
(4) Fatty acids enter as Pyruvate
