Document Summary
Lecture 33 mitochondria and the krebs cycle. Inner membrane that fold inward in ridges called cristae. Mitochondrial cristae: there are many small particles (originally called elementary particles, discovered by roberto. Fernandez peru) that cover the surface of the cristae: these particles are now called f1f0atpase. Mitochondrial matrix: contains many soluble enzymes, ribosomes, mitochondrial dna, and ca2+. Some proteins are synthesized by mitochondria itself using mrna derived from mitochondrial. Dna: many proteins however, are constructed using dna from the cell nucleus, these cells are made in the cytoplasm. Proteins made in the cytoplasm are tagged and brought by carrier proteins to the mitochondria. Pyruvate is produced via glycolysis, it is transported to the mitochondria and there pyruvate is converted to acetyl coenzyme a and nad(h). Krebs discoveries: he found that some sugars changed the rate of a reaction but were not consumed, like malate and citrate, others were consumed, like pyruvate.
