Question

fill in the blank question

complex i in the electron transport chain accepts electrons from the carrier called blank.

Explanation:

Identify the electron donor for Complex I

Complex I (NADH:ubiquinone oxidoreductase) is the first enzyme complex of the respiratory electron transport chain. It catalyzes the transfer of two electrons from NADH to ubiquinone (coenzyme Q).

Determine the specific carrier name

The carrier molecule that donates electrons directly to Complex I is NADH (nicotinamide adenine dinucleotide).

Answer:

Complex I in the electron transport chain accepts electrons from the carrier called <blank>NADH</blank>.
