Large protein that uses energy

from H⁺ ions to bind ADP and

a phosphate group together

to produce ATP.

(flavine adenine dinucleotide)

Molecules that are similar to NAD⁺

and NADH, respectively.

TRANSPORT
CHAIN

a series of proteins in which

high-energy electrons from the

Krebs Cycle are used to convert

ADP to ATP.

Acetyl-CoA adds 2-carbon acetyl

 group to a 4-carbon molecule,

producing a 6-carbon molecule.

Produced from ADP...

ENERGY!!
