4 Steps of Aerobic Respiration livestrong

WebThe next step in aerobic respiration is the formation of acetyl coenzyme A. In this step, pyruvate is brought into the mitochondria to be oxidized, creating a 2-carbonacetyl group. This 2-carbon acetyl group then binds with coenzyme A, forming acetyl coenzyme A. The acetyl coenzyme A is then brought back into the mitochondria for use in the ... WebAug 13, 2024 · There are two types of cofactors: inorganic ions [e.g., zinc or Cu (I) ions] and organic molecules known as coenzymes. Most coenzymes are vitamins or are derived from vitamins. Vitamins are organic compounds that are essential in very small (trace) amounts for the maintenance of normal metabolism.
