Astudent assisting with the experiment would observe all of the following about the electron transport chain except: a. electrons are passed from carriers with lower reduction potential to those with higher reduction potential. b. the first electron carrier is also a proton pump. c. all electron carriers are mobile and hydrophobic. d. the electron carriers can transport a maximum of 2 electrons.

C. All electron carriers are mobile and hydrophobic

Explanation:

Hello,

In this case, it is widely known that the electron carriers move inside the inner mitochondrial membrane and consequently move electrons from one to another. In such a way, they are mobile, therefore they are largely hydrophobic as long as they are inside the membrane.

For instance, the cytochrome c is a water-soluble protein in a large range, therefore, the answer is: C. All electron carriers are mobile and hydrophobic.

Best regards.
