Lecture 12-Objectives Describe the fate of electrons during a  catabolic process. Define oxidation and reduction reactions with  respect to electron position or localization. Describe the role of NAD +  in the oxidation of  glucose under anaerobic conditions.  Know where glycolysis and the Krebs cycle  occur in a eukaryotic cell.

Lecture 10-Objectives Define “substrate level phosphorylation” and name  the enzymes involved in substrate level  phosphorylation. Know the reactions of glycolysis. Recognize and name the intermediates and the  enzymes of glycolysis. Contrast the fate of glucose under anaerobic  conditions in yeast and in a typical eukaryotic cell  from a higher organism.

Lecture 10-Objectives Know the fate of glucose in glycolysis under  aerobic conditions. Know the fate of pyruvate under aerobic  conditions and where this reactions occurs in  eukaryotic cells. Name the enzyme that converts pyruvate to  acetyl-CoA

Glycolysis and Cellular Respiration The aim of the next few lectures is to understand  how chemical bond energy is extracted from  glucose to drive the synthesis of ATP from ADP. Remember: The oxidation of glucose is a catabolic  exergonic process. The energy released from this process is used  to synthesize ATP. How does this occur?

Glycolysis and Cellular Respiration During the degradation of glucose, the first part of the  catabolic process is fermentation. It is an anaerobic process requiring no O 2.   It is probably the oldest pathway for the synthesis of  ATP since the earth originally had an anaerobic  environment. Fermentation is only a partial degradation of  glucose and it is not efficient in ATP synthesis.

Glycolysis and Cellular Respiration Glycolysis is a prelude to a more efficient process for  ATP synthesis - cellular respiration. Cellular respiration is an aerobic process; requiring O
