The Chemiosmotic Hypothesis

Q. What is oxidative phosphorylation?

Q. Proton gradient helps in:

1. ATP synthesis
2. NADPH synthesis
3. Providing electrons to PS-ll
4. Providing oxygen to PS-ll

Q. What is ATP?

1. Primary energy carrier
2. Enzyme
3. Catalyst
4. Both b and c

Q. Which of the following is not required for the synthesis of ATP by chemiosmosis?

1. Proton pump
2. NADPH
3. Proton gradient
4. ATP Synthase

1. Peter D Mitchell
2. Charles Darwin
3. Mendel
4. Alfred Russell

Q. During ATP synthesis, movement of electrons occurs from

1. lumen of thylakoids to membrane of thylakoids
2. lumen of thylakoids to stroma of thylakoids
3. membrane of thylakoids to stroma of thylakoids
4. stroma of thylakoids to lumen of thylakoids
