Verified step by step guidance1
Understand the concept of electron carriers: Electron carriers are molecules that transport electrons during cellular respiration. They exist in oxidized and reduced forms.
Identify the reduced forms: In the context of electron carriers, the reduced form is the one that has gained electrons.
Analyze the options: Look at each option to determine which is in its reduced form. FADH2 and NADH are reduced forms because they have gained electrons.
Compare the options: FADH2 is the reduced form of FAD, and NADH is the reduced form of NAD+.
Conclude the correct answer: Based on the options provided, NADH is the correct answer as it is an electron carrier in its reduced form.
