Q.

Which of the following is essential for the conversion of pyruvic acid to acetyl CoA?

1. TPP

2. NAD

3. LAA

4. ATP

Q.

Oxidative phosphorylation is the production of

1. NADH during respiration

2. ATP during photosynthesis

3. ATP during respiration

4. NADPH during photosynthesis

Q.

What molecule will form when hydrogen ions flow down the electrochemical gradient through ATP synthase complexes in mitochondria?

1. water

2. ADP

3. ATP

4. carbon dioxide

Q. Which of the following molecules are electron carriers and are capable of producing ATP in the repiratory pathway?

1. $\text{NADPH}$ and $FAD{H}_2$
2. $\text{NADH}$ and $FAD{H}_2$
3. NADPH

Q. Which one of the following mammalian cells are not capable of metabolising glucose aerobically?

1. RBCs
2. WBCs
3. unstriated muscle cells
4. liver cells

Q. in water splitting during z scheme elwctron is used up for z scheme but what happens to o and proton.? where did thsy go and then how are they utilized by plant body?

Q. When yeast growing anaerobically in glucose-rich-environment is exposed to oxygen in sufficient quantity, its rate of glucose utilization decreases. This phenomenon is known as the Pasteur effect. Adding an un-coupler of oxidative phosphorylation would have what effect on Pasteur effect?

1. Pasteur effect will be enhanced
2. Pasteur effect will remain unchanged
3. Pasteur effect will not take place
4. Variable effect

Q. Mark the incorrect statement.

1. Breaking of C–C bonds of complex organic molecules by oxidation in cells leading to the release of a lot of energy is called cellular respiration
2. Initial stage of cellular respiration takes place in cytoplasm

3. Incomplete oxidation of pyruvate by the stepwise removal of all the hydrogen atoms leaves three molecules of $C{O}_2$

4. TCA cycle starts with the condensation of acetyl group with OAA and $H_{2}O$ to yield citric acid

Q.

The correct sequence for aerobic metabolic breakdown of glucose is

1. glycolysis--preparatory reaction--cirtric acid cycle--electron transport system

2. preparatory reaction--glycolysis--electron transport--citric acid cycle

3. electron transport system--citric acid cycle--preparatory reaction--glycolysis

4. light reactions--electron replacement--ATP production--calvin cycle

Q.

give difference between oxidative phosphorytation and electron transport system.?

Q. Body tissues obtain O${}_2$ from oxyhaemoglobin because of its dissociation caused by

1. Low O${}_2$ concentration
2. Low CO${}_2$ concentration
3. Low O${}_2$ and high CO${}_2$ concentration
4. High CO${}_2$ concentration
