1. Draw a reaction map of glucose completely metabolized to CO 2 + H 2 O in the presence of oxygen25 Points Reference: http://employee.heartland.edu/hfei/http://employee.heartland.edu/hfei/ Under: Biol 161-02 / Class Materials / Unit 2 / Lecture Slides / Chapter 8 Requiresments: 1.Chemical formula; 2.Enzymes, co-enzymes, and co-products;15 points 3.Calculate ATP formation through aerobic metabolism. Adding up of ATPs from four courses: 1.direct formation by a reaction 2.from GTP 3.from NADH 4.from FAD2 5 points 4.Trace C1 of glucose through the pathway as far as you can. 5 points Bonus (2 points): If C1 of glucose is labeled, how many rounds of Krebs Cycle do you expect it to take for it to be completely released as CO 2 ?
