Cell respiration is carried out by
(1) ribosome
(2) mitochondria
(3) chloroplast
(4) Golgi bodies
The process by which ATP is produced in the inner membrane of a mitochondrion. The electron transport system transfers protons from the inner compartment of the outer; as the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADP, forming ATP.
(1) Chemiosmosis
(2) Phosphorylation
(3) Glycolysis
(4) Fermentation
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
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. | \( \dfrac{\mathrm{ Volume ~ of ~ O_{2} ~evolved }}{\mathrm{Volume~ of ~CO_{2} ~consumed }}\) |
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
After glycolysis, fate of glucose in mitochondrial matrix is
1. oxidation
2. reduction
3. oxidative decarboxylation
4. hydrolysis.
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
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.
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
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) |
