Question

Electron carrier molecules transfer electrons between metabolic pathways. Choose the electron carriers that transfer electrons from glycolysis to the electron transport chain and from the citric acid cycle to the electron transport chain. One of the molecules will be placed more than once, and one answer box will have two molecules.

Answer 1

Glycolysis NADH.

Citric Acid cycle-NADH and FADH2

The electrons are locked in the Hydrogen atoms carried by the coenzymes.

In the protein carriers,of the matrix in of the mitochondrial and stroma space of chloroplasts; electrons are unbounded by the striping of hydrogen into protons and electrons.

The electrons moved into the electron transport chains.
