The chemiosmotic hypothesis

Q.

What occurs during chemiosmosis in chloroplasts?

Q.

Where is chemiosmosis in photosynthesis?

Q. The chemiosmotic hypothesis invovles all of the following, except

1. A membrane impermeable to photons.
2. Only proton transport is strictly regulated, other positively charged ions can diffuse freely across the mitochondrial membrane.
3. ATPase activity is reversible.
4. Electron transport by the respiratory chain pumps proton out of the mitochondria.

Q.

What are the phases of clathrin-mediated endocytosis?

Q. Who proposed the term, "alpha", "beta" and "gamma" in taxonomy?

1. Lederberg
2. Turrill
   
3. Huxley
4. Lamarck

Q. Chemiosmosis requires a

1. Proton pump
2. Proton gradient
3. All of the above
4. Membrane

Q. RBC and a plant cell (with thick cell wall) are placed in distilled water. The concentration of the solute is the same in both the cells.

What changes would be observed in them?

1. Both the plant cell and RBC would not undergo any change
2. RBC would increase in size and burst, while the plant cell would remain about the same size
3. The plant cell would increase in size and burst, while RBC would remain about the same size
4. Both the plant cell and RBC would decrease in size and collapse

Q. What is Na^+ / K^+ pump seen in animal cell ( by the process of active transport ) ?

Q. Chemiosmotic hypothesis was proposed by

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