Learning objectives At the end of this lecture, you will be able to: 1) Describe the locations of pyruvate processing and the citric acid cycle in Prokaryotes and Eukaryotes. 2) Explain the processing and regulation of processing pyruvate. 3) Discuss the major steps, regulation, and outcome of rounds of the citric acid cycle.

1. Cellular respiration is any suite of reactions that produces ATP in an electron transport chain. 4. Electron transport and chemiosmosis – compounds that were reduced in steps 1–3 are oxidized in reactions leading to ATP production. Cellular respiration has four steps: 1. Glycolysis – glucose is broken down to pyruvate. 2. Pyruvate processing pyruvate is oxidized to form acetyl CoA. 3. Citric acid cycle – acetyl CoA is oxidized to CO 2 .

, the remaining cellular respiration reactions occur in the mitochondria. In Eukaryotes, pyruvate produced during glycolysis is transported from the cytosol into the mitochondria. In Prokaryotes, the Citric acid cycle takes place in the cytoplasm.
