Q.

Does chemiosmosis occur in photosynthesis and cellular respiration?

Q. Oxidative phosphorylation refers to

1. Production of ATP by chemiosmosis
2. Anaerobic production of ATP
3. Alcoholic fermentation
4. The citric acid cycle production of ATP

Q. In mitochondria, protons accumulate in the

Q.

How much ATP is used in photosynthesis?

Q. Assertion: Chemiosmosis requires a membrane, a proton pump, a proton gradient and $ATP$ase.

Reason: The proton gradient is broken down due to movement of proton across the membrane to the lumen through the transmembrane channel of the $F_0$ of the $ATP$ase.

Reason: All life forms were formed in water environment only.

1. Both the assertion and reason are true and the reason is the correct explanation of the assertion
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion
3. Assertion is true but the reason is false
4. Both assertion and reason are false

Reason (R): The number of $\mathrm{ATP}$ molecules synthesised depends on the nature of the electron donor.

1. Both assertion and reason are true and the reason is the correct explanation of the assertion
2. Both assertion and reason are true but the reason is not the correct explanation
3. Both assertion and reason are false
4. The assertion is true but the reason is false

Q. In plants, during aerobic respiration

1. ADP is converted to ATP
2. carbohydrates are synthesized
3. oxygen is released
4. none of the above

Q.
