Question
**Scenario:**

You have isolated a bacterium which is a strict, obligate aerobe. You expose the bacterium to oxidative phosphorylation uncouplers. What will first happen to the bacterium, if anything?

**Options:**

- ○ Electron transport by the ETC will stop
- ○ Nothing will happen to the bacterium
- ○ The proton gradient will be diminished thus reducing ATP synthesis
- ○ Proton pumping will stop

**Explanation:**

The image presents a multiple-choice question describing a biological process involving a bacterium's response to oxidative phosphorylation uncouplers. The options address potential impacts on the electron transport chain (ETC) and ATP synthesis.
