When cell energy levels are high, phosphofructokinase-1 (PFK-1) is activated in the fed state
by_____ - ANS ✔✔Fructose 2,6 Bisphosphate
The end product(s) of gluconeogenesis include - ANS ✔✔Glucose
High levels of acetyl CoA increases the activity of the enzyme _______ found in the
gluconeogenic pathway within the ______tissue. - ANS ✔✔pyruvate carboxylase, liver
The conversion of pyruvate to oxaloacetate is a reaction found in which of the following
pathway(s): - ANS ✔✔gluconeogenesis
Which intermediate of glycolysis is split into isomers, which is responsible for making 2 copies of
products for subsequent reactions? - ANS ✔✔Fructose 1,6 Bisphosphate
When oxygen is not available_____ is generated to produce _____, which allows _______ to
keep running. - ANS ✔✔Lactate, NAD+, glycolysis
The products of aerobic glycolysis includes _______ - ANS ✔✔2 pyruvate, 2 NADH+H, 2 ATP
An enzyme reaction that incorporates water is an example of a ________. - ANS ✔✔hydrolase
When oxidative phosphorylation decreases this results in the accumulation of _______, which
causes the ________ to stop. This indicates the cell _____ATP. - ANS ✔✔NADH, Krebs Cycle, has
enough ATP
, NADH+H generates 3 ATP compared to the 2 ATP generated by FADH2 during oxidative
phosphorylation because NADH+H generates ______ by directly donating to Complex___. - ANS

small molecules to create ATP.
What is the general purpose of anabolic processes? - ANS ✔✔Uses ATP and reducing agents to
synthesize large molecules from large molecules to store food as energy.
