FINAL
Which of the following can enter glycolysis without additional reactions?
Both products from maltose after maltase treatment
Which glycolysis intermediate is correctly matched to its connected anabolic pathway product?
Dihydroxyacetone-P; Triglycerides
Which of the following is NOT an outcome of glycolysis? Generation of 2 net ATP molecules Generation of 2 NADH Generation of 2 H2O Correct Response Generation of 1 Pyruvate
Generation of 1 Pyruvate
Which metabolic pathway is an example of a catabolic pathway in animals?
Glycogen degradation
In which situation is glycolysis alone likely to be a major contributor to ATP generation?
In erythrocytes
Under anaerobic conditions, pyruvate is metabolized to either ethanol or lactate to provide which important coenzyme?
NAD+
Which enzyme's activity is controlled by the levels of glucose-6-P and fructose-6-P in the cell?
Phosphoglucoisomerase
Which enzyme is NOT readily reversable, and can therefore be used in both glycolysis and gluconeogenesis?
Phosphoglycerate mutase
How do the sources of glucose for glycolysis differ between plants and animals?
Plants obtain glucose via carbon fixation
Which of the following fates of pyruvate is correct? Pyruvate is fermented to ethanol under aerobic conditions Pyruvate enters the citrate cycle under anaerobic conditions Pyruvate is converted to lactate under aerobic conditions Correct Response Pyruvate enters the citrate cycle under aerobic conditions
Pyruvate enters the citrate cycle under aerobic conditions
Which of the following is least likely to affect the metabolic flux of a metabolic pathway? Large influx of substrate Decoupling of a favorable and an unfavorable reaction Correct Response Steady-state substrate concentrations Formation of a multienzyme complex by pathway enzymes
Steady-state substrate concentrations
In nature, glucose is
known as gluocopyranose when in its cyclic form.
Lactose intolerance is caused by
reduced expression of the lactase gene.
Glucokinase is important for the regulation of glycolysis because it:
traps extra glucose in liver cells for glycogen production.
Which metabolic pathway is only found in plants?
Carbon fixation
