Which of the following carriers transfers electrons and protons? (Select all that apply.)
NADH
Nonheme iron-sulfur proteins
ubiquinone
FAD
Homework Answers
NADH
- It carry one H+ and two electrons.
- It act as a source of energy in many metabolic process.
- complex I uses NADH2 for electron source.
FAD
- It carry two proton two electrons .
- It also act as source of energy in electron transport chain FADH2 is utilised by complex II.
