Q. No.
The energy-releasing metabolic process in which substrate is oxidised without an external electron acceptor is called
1. glycolysis
2. fermentation
3. aerobic respiration
4. photorespiration
Aerobic respiratory pathway is appropriately termed
1. catabolic
2. parabolic
3. amphibolic
4. anabolic
The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that Adenosine Triphosphate (ATP) is formed because
| 1. | high energy bonds are formed in mitochondrial proteins |
| 2. | ADP is pumped out of the matrix into the intermembrane space |
| 3. | a proton gradient forms across the inner membrane |
| 4. | there is a change in the permeability of the inner mitochondrial membrane toward Adenosine Diphosphate (ADP) |
The overall goal of glycolysis, Krebs cycle and the electron transport system is the
formation of:
1. ATP in small stepwise units
2. ATP in one large oxidation reaction
3. Sugars
4. Nucleic acids
Glycolysis is found in cytoplasm of virtually all types of aerobic/anaerobic cells. In this
process, glucose is converted into :
1. PEP
2. acetyl CoA
3. pyruvic acid
4. citric acid.
Which of the following is the connecting link between glycolysis and Krebs cycle?
(1) Acetyl Co-A
(2) Oxalosuccinic acid
(3) Pyruvic acid
(4) Citric acid
After glycolysis, fate of glucose in mitochondrial matrix is
1. oxidation
2. reduction
3. oxidative decarboxylation
4. hydrolysis.
In which of the following reactions of glycolysis, a molecule of water is removed from the substrate?
1. Glucose Glucose-6-phosphate
2. Fructose-6-phosphate Fructose-1,6 bisphosphate
3. 2-phosphoglycerate Phosphoenol pyruvate
4. Phosphoenol pyruvate Pyruvate
RQ (Respiratory Quotient) is defined as
| 1. | \(\mathrm{Volume~ of ~CO_{2} ~evolved } = \mathrm{ Volume ~ of ~ O_{2} ~ consumed}\) |
| 2. | \( \dfrac{\mathrm{ Volume ~ of ~ O_{2} ~ consumed}}{\mathrm{Volume~ of ~CO_{2} ~evolved }}\) |
| 3. | \(\dfrac{\mathrm{Volume~ of ~CO_{2} ~evolved }}{\mathrm{ Volume ~ of ~ O_{2} ~ consumed}}\) |
| 4. | \( \dfrac{\mathrm{ Volume ~ of ~ O_{2} ~evolved }}{\mathrm{Volume~ of ~CO_{2} ~consumed }}\) |
What is the correct order of the stages of cellular respiration?
1. Krebs' cycle electron- transport- chain glycolysis
2. Electron transport chain- Krebs' cycle - glycolysis
3. Glycolysis - Krebs' cycle - electron transport chain
4. Glycolysis - electron transport chain - Krebs' cycle
