Define: ATP synthase Oxidative phosphorylation Ribulose-bisphosphate Carboxylase Oxygenase (2) 2. The cyclic series of chemical reactions known as the Krebs cycle involves enzymes located within the ________________________________________ in eukaryotic cells and in the ________________________ of prokaryotic cells. Since mitochondria evolved from prokaryotic cells in the phylum Proteobacteria, these two regions are equivalent. (2) 3. The primary function of the Krebs cycle as initially described in lecture is the catabolism of organic compounds, specifically the _______________________________ of organic acids (isocitric acid and alpha- ketoglutaric acid). Most of the energy released in association with these reactions is captured in the form of _______________ a reduced coenzyme, but some is captured as FADH2 and some as ATP (or sometimes GTP). (1) 4. The Krebs cycle is described as being cyclic, because the last acid formed (oxaloacetic acid) serves as the four-carbon substrate binding with the two- carbon acetyl group removed from _________________________ when citric acid is formed at the start of the next cycle.
