UMN BIOC 3021: Exam 3 Questions and
Answers
inter mitochondria membrane - Answers✓✓e- transport and oxidative phosphorylation occur
here
oxidative proton pumps - Answers✓✓hydrogen ion gradient created by
catabolic pathways - Answers✓✓usually oxidative, usually release energy
anabolic pathways - Answers✓✓synthetic, usually involve reduction, use energy
gamma and beta phosphates - Answers✓✓terminal phosphates of ATP, release hight amounts
of energy upon hydrolysis
adipose tissue - Answers✓✓storehouse for fat in the form of triacylglycerols
glucokinase - Answers✓✓enzyme used to replace hexokinase in glycolysis when performed in
the liver
insulin - Answers✓✓allows glucose into the liver

substrate level phosphorylation - Answers✓✓a process in which a phosphate residue is directly
transferred from an organic phosphorylated intermediate to ADP to make ATP
oxidative phosphorylation - Answers✓✓uses the downhill transport of high energy electrons to
form a proton gradient
highest negative delta G (in hydrolysis) - Answers✓✓phosphoenolpyruvate
liver - Answers✓✓accumulated lactate is released from muscle cells into the blood and is
carried here where it is converted back into glucose
ethanol fermentation and lactate fermentation net yield - Answers✓✓2 ATP (no NADH)
three essentially irreversible rxns in glycolysis - Answers✓✓glucose to glucose-6-phosphate,
fructose-6-phosphate to fructose-1,6-bisphosphate, phosphoenolpyruvate to pyruvate
ATP utilization of gluconeogenesis - Answers✓✓6 ATP equivalents
Cori Cycle - Answers✓✓physiological process that occurs when glucose is converted to lactate
during intense exercise, and when lactate is converted back to glucose during the recovery
period
regulation of bypass sites - Answers✓✓most stringent regulation, regulation focused here
because distinct enzymes allow for regulating one direction and not the other, involves
allosteric control, also subject to negative feedback
energy charge formula - Answers✓✓1/2 ((2ATP + ADP)/(ATP + ADP + AMP))
