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.

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

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?
(a) Glucose $\to$ Glucose-6-phosphate
(b) Fructose-6-phosphate $\to$ Fructose-1,6 bisphosphate
(c) 2-phosphoglycerate $\to$Phosphoenol pyruvate
(d) Phosphoenol pyruvate $\to$Pyruvate

RQ (Respiratory Quotient) is defined as

(1) $\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{evolved} = \mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{consumed}$

(2) $\frac{\mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{consumed}}{\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{evolved}}$

(3) $\frac{\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{evolved}}{\mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{consumed}}$

(4) $\frac{\mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{evolved}}{\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{consumed}}$
