Question

72. How many rounds of -oxidation would be needed to convert palmitic acid to acetyl-CoA?

A. 1

B. 7

C. 8

D. 16

E. 14

73. The process of _____ converts glucose into _____.

A) electron transport; CO2

B) glycolysis; pyruvate

C) glycogenolysis; glycogen

D) gluconeogenesis; glycogen

E) glycogen synthesis; pyruvate

78. Glyceraldehyde-3-phosphate dehydrogenase oxidizes _____.

A) an alcohol to a ketone

B) a carboxylic acid to CO2

C) an alcohol to an aldehyde

D) an aldehyde to a carboxylic acid

E) an aldehyde to an alcohol

80. In oxidative phosphorylation, complex III accepts electrons from _____ and transfers them to _____.

A) cytochrome c; cytochrome a

B) ubiquinol; cytochrome c

C) ubiquinone; cytochrome c

D) ubiquinol; cytochrome b

E) ubiquinone; cytochrome a

72) C. 8

palmitic acid is a 16 carbon fatty acid and in every cycle 2 carbons are cleaved so 8 cycle total

73) B) glycolysis; pyruvate

One glucose molecule is broken down into two molecules of pyruvate in the cytoplasm in glycolysis

78) D) an aldehyde to a carboxylic acid

first reaction is the oxidation of glyceraldehyde 3-phosphate coupled to an aldehyde is converted into a carboxylic acid

80) B) ubiquinol; cytochrome c

for complex III QH2 is the donor and cytochrome c is the acceptor of electrons QH2 is ubiquinol in these systems

The electron is transfered from donor to acceptor
