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
