ATP, NADH and FADH2

Explanation: In citric acid cycle, Acetyl CoA combines with oxaloacete and in a series of enzyme catalyzed reactions generate one molecule of ATP (in form of GTP), one molecule of FADH2 and three molecules of NADH. FADH2 and NADH are channeled into the electron transport chain where they are used to generate more ATP.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
