Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are electron carrier molecules?
A
Molecules that transfer high energy electrons to other molecules
B
Molecules that carry energy from one reaction to another
C
Molecules that make ATP
D
Molecules that have little dogs that fit in their purse
Explanation: 

Detailed explanation-1: -There are two electron carriers that play particularly important roles during cellular respiration: NAD+ (nicotinamide adenine dinucleotide, shown below) and FAD (flavin adenine dinucleotide).

Detailed explanation-2: -ATP is a high-energy molecule that stores and transports energy within cells. NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.

Detailed explanation-3: -NADH and FADH2 carry high-energy electrons to the electron transport chain in cellular respiration. NADPH carries high-energy electrons to the electron transport chain in photosynthesis.

Detailed explanation-4: -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. Nicotinamide adenine dinucleotide (NAD+) is an example of electron carrier.
