Question 6:

6. (2pts) Glutamate (5 carbon molecule) can be degraded to NH4, CO2, and H2O to produce ATP energy. It enters TCA cycle through -ketoglutarate (Glutamate - ketoglutarate, No ATP, NADH or FADH2 production/consumption at this step). How many ATP molecules can be generated from complete oxidation of each molecule of this amino acid? (show your calculations, using NADH 2.5 ATPs and FADH,-1.5 ATPs. ignore any transport cost. Hint: Complete oxidation means that ALL five carbons will ultimately be fully oxidized to CO2 and the electrons will be passed offto the redox cofactors to go into the ETC and make ATP) 7. (2 pts) For each of the four Electron Transport Chain complexes list:

Explanation / Answer

glutamate ----> succinic acid ----->oxaloacetate 7.5 ATP

then two complete kreb cycles giving 10 ATP each

therefore total =7.5+20= 27.5 ATPs
