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: -In these steps, electrons from glucose are transferred to small molecules known as electron carriers. The electron carriers take the electrons to a group of proteins in the inner membrane of the mitochondrion, called the electron transport chain.

Detailed explanation-2: -NADP+ (nicotinamide adenine dinucleotide phosphate) – carrier molecule that transfers high-energy electrons from chlorophyll to other molecules. It accepts and holds two high-energy electrons and a hydrogen to become NADPH.

Detailed explanation-3: -Abstract: The electron transport chain (ETC) is the major consumer of O2 in mammalian cells. The ETC passes electrons from NADH and FADH2 to protein complexes and mobile electron carriers. Coenzyme Q (CoQ) and cytochrome c (Cyt c) are mobile electron carriers in the ETC, and O2 is the final electron recipient.
