The NADP reductase enzyme is located:
1. | within the thylakoid membrane |
2. | on the stroma side of the thylakoid membrane |
3. | on the lumen side of the thylakoid membrane |
4. | in the thylakoid lumen |
The ATP synthase consists of two parts where:
1. | is a transmembrane channel and protrudes out towards stroma |
2. | is a transmembrane channel and protrudes out towards stroma |
3. | is a transmembrane channel and protrudes out towards lumen of thylakoid |
4. | is a transmembrane channel and protrudes out towards lumen of thylakoid |
Chemiosmosis in chloroplasts is possible because of:
1. | establishment of a proton gradient across the thylakoid membrane. |
2. | diffusion of electrons through the ATP synthase. |
3. | osmosis of water from thylakoid to stroma. |
4. | presence of large amount of oxygen in the stroma. |
In chloroplasts, protons are actively pumped from
1. the intermembrane space to the matrix.
2. the matrix to the stroma.
3. the stroma to the thylakoid space.
4. the thylakoid space to the intermembrane space.
The ATP synthase complexes in a plant cell are located:
I: | in the thylakoid membrane |
II: | in the plasma membrane |
III: | in the inner mitochondrial membrane |
1. | I and II only | 2. | I and III only |
3. | II and III only | 4. | I, II and III |
I: | Plastoquinone is located within the membrane |
II: | Plastocyanin is located on the inner lumen side of the membrane |
III: | NADP reductase is located on the stroma side of the membrane |
1. | Only I and II are correct |
2. | Only I and III are correct |
3. | Only II and III are correct |
4. | I, II and III are correct |
Statement I: | CF1 particle of ATP synthase makes ATP molecules. |
Statement II: | CF1 particle of ATP synthase is embedded in the thylakoid membrane and forms a transmembrane channel that carries out facilitated diffusion of protons across the membrane. |
1. | Both Statement I and Statement II are correct |
2. | Both Statement I and Statement II are incorrect |
3. | Statement I is correct but Statement II is incorrect |
4. | Statement I is incorrect but Statement II is correct |
