Dr. Leisha Mullins BIOCHEMISTRY 411/602 Spring 11 Homework 7 Print Name: ________________ Section Number: ______________ BIOCHEMISTRY 411/602 Homework Assignment 7 10 points Due: Tuesday March 8 1 (2 pts). Write a balanced net reaction for the conversion of each of the following to CO2 via glycolysis, the citric acid cycle, and oxidative phosphorylation (as required). What is the net yield of ATP? (1 NADH = 2,5ATP, 1 FADH2 = 1.5 ATP). A. Fructose (via glycerol phosphate shuttle) B. ethanol (via malate aspartate shuttle) C. glycerol (via glycerol phosphate shuttle) D. Lactose (via malate aspartate shuttle) 2 (2 pts). Draw an O2 consumption curve for a suspension of isolated mitochondria when the following compounds are added in the indicated order. Indicate on the curve the effect of each compound as it is added. With the addition of each compound, all of the previously added compounds remain present. The experiment starts with a high

ADP added c. Rotenone added d. Succinate added e. ADP runs out f. DNP added 3 (1 pts). Calculate the proton motive force across the inner mitochondrial membrane at 25C when the electrical is 0.018V (inside negative) and the pH outside is 6.3 and the pH INSIDE is 7.2 4. ( 5 pts) A. Draw the entire pathway for the incorporation of 3 CO2s into the Calvin Cycle via the C4 pathway (i.e. draw both the C4 pathway and the Calvin cycle) B. How many ATP equivalents and NAPDPH are required: per CO2 for the Calvin Cycle only? per CO2 for the C4 Pathway only? per CO2 for for the combined C4 pathway and the Calvin cycle? for the complete formation of Glucose via the Calvin Cycle in C3 plants? for the complete formation of Glucose via the Calvin Cycle in C4 plants?...
