Kreb's Cycle. When oxygen is present, cellular respiration continues after glycolysis with a process called the Kreb's cycle. In the Kreb's cycle, Acetyl CoA combines with a four-carbon compound in the mitochondria.lycolysis also produces some waste in the form of carbon dioxide, which is exhaled, and an acetyl group called pyruvic acid, which then joins with coenzyme A for the next step of cellular respiration.
