This preview shows page 17 - 23 out of 26 pages.

A. cyclic AMP is an inhibitor of protein kinase AB. serine is often phosphorylated
C. dephosphorylation occurs when ATP is regeneratedD. phosphatase catalyzes a transfer of a phosphate
Feedback: Learning Objective: Recognize the role of phosphorylation in the transmission of intracellular signalsQuestion 29 of 402.5 PointsWhat vitamin acts as a coenzyme in cell respiration and is important in alcohol fermentation?
Feedback: Learning Objective: Describe the type of fermentation that readily occurs in animal cells and the conditions that initiate that fermentationQuestion 30 of 402.5 PointsTo efficiently provide the ideal amount of nitrogen fertilizer, some farmers make use of a
“chlorophyll meter” that measures the amount of green light reflected off a leaf.Why does this provide an indication of whether the plant may need more or less nitrogen?
Feedback: CorrectQuestion 31 of 402.5 PointsWhat is the relationship between cellular aerobic respiration and photosynthesis?
Feedback: Learning Objective: Explain how photosynthesis works in the energy cycle of all living organismsQuestion 32 of 402.5 PointsWhen has glucose been broken down from its original 6 carbon molecule to 2 carbon dioxides inthe citric acid cycle?A. oxidation of pyruvateB. CoA is bound to sulfhydryl group C. when isocitrate is oxidized to α-KetoglutarateD. when α-Ketoglutarate is oxidized to Succinyl CoA
E. condensation of acetyle-CoA with oxaloacetate
Feedback: Learning Objective: Explain how a circular pathway, such as the citric acid cycle, fundamentally differs from a linear pathway, such as glycolysisQuestion 33 of 402.5 PointsPhosphofructokinase, a controlling enzyme of glycolysis, is inhibited by ___ and activated by ___.
