please note for cr/nc mode only: faculty has the option of recording either the letter grade or the cr or nc grade on the grade roster. The system will automatically convert the letter grade to the appropriate CR/NC grade based on the rule for the student level. r REMEDIAL NORMAL GRADE - The course is a remedial course and faculty will assign a normal grade.
The complete oxidation of glucose is the process which turns glucose into water, carbon dioxide and energy. Glucose oxidation occurs in the cells and is part of cellular respiration. Oxidation of glucose, also known as glycolysis, is the process which releases energy stored in glucose by combining it with oxygen. During glycolysis, carbon, hydrogen and oxygen in one molecule of glucose recombine with six molecules of oxygen.
The oxidation of glucose begins during glycolysis. NAD+ accepts the electrons during the oxidation, and as a result it gets reduced. A total of 2 NADH are produced. Recall that NAD+ is a coenzyme (organic compound required by an enzyme for activity) that is used in redox reactions. Enzymes that catalyze redox reactions with the help of coenzymes such as NAD+ are called dehydrogenases. Pyruvic acid is a branch point. It still has much energy and can be further degraded. If oxygen is present (aerobic conditions) pyruvate is metabolized via cellular respiration (i.e., citric acid cycle and ETC. Without oxygen, anaerobic conditions, pyruvate is metabolized via fermentation.
