Question

Complete each sentence based on the electron-transfer process pictured below.

Answer 1

Electron transfer in a photosynthetic system occurs between photosystem II (PS-II) and photosystem I (PS-I) during the light-dependent reactions.

Step-by-step explanation:

Electron transfer in a photosynthetic system occurs between photosystem II (PS-II) and photosystem I (PS-I) during the light-dependent reactions. In this process, PS-II captures light energy and uses it to transfer electrons from water to a molecule called plastoquinone (PQ), creating a proton gradient and generating ATP. The electrons are then transferred from PQ to cytochrome b6f complex, and finally to PS-I, where they are used to reduce NADP+ to NADPH. This pathway of electron transfer is essential for the production of ATP and NADPH, which are used in the light-independent reactions of photosynthesis.

Answer 2

1. A is gaining electrons
2. B is staying the same
3. A is being reduced
4. B is being oxidized
5. A is the reducing agent
6. B is the oxidizing agent
7. The oxidation state of A is decreasing
8. The oxidation state of B is increasing

Step-by-step explanation:

In an electron-transfer process, one species gains electrons while another species loses electrons. In this case, A is gaining electrons, which means it is being reduced. B, on the other hand, is not gaining or losing any electrons, so it is staying the same in terms of its number of electrons.

Since A is gaining electrons and being reduced, its oxidation state is decreasing. Conversely, B is losing electrons and being oxidized, so its oxidation state is increasing.

To summarize:

- A is gaining electrons, being reduced, and its oxidation state is decreasing.

- B is staying the same in terms of its number of electrons, being oxidized, and its oxidation state is increasing.
