Question

6. A researcher decides to isolate thylakoid membranes and add protons to the space inside the thylakoids by soaking the thylakoids in acetic acid, which diffuses through the membrane, and then washing the thylakoids very quickly. What will happen?

• A. The scheme will run in reverse.

• B. ATP will be able to be made without light.

• C. Light will be emitted by the thylakoids.

• D. The membranes will dissolve.

Answer 1

B. ATP will be able to be made without light.

Step-by-step explanation:

Just wanted to confirm the answer, in case people doubt the person above me. Their explanation is also correct.

Answer 2

The answer is; B

When an electron is split from a water molecule by sunlight, the electron is channeled through several protein complexes that harness the energy of the electron to pump protons across the membrane to the space inside the thylakoid. Therefore, light plays an important role in developing the protonmotive force used to make ATPs.

In this experiment, the protonmotive force is created without sunlight.
