Electron carrier

Definition

noun, plural: electron carriers

A molecule capable of accepting one (or more than one) electrons from another molecule (electron donor), and then ferry these electrons to donate to another during the process of electron transport.


Supplement

Nicotinamide adenine dinucleotide (NAD+) is an example of electron carrier. It carries electrons in redox reactions within the cells.
