What is the ultimate fate of the carbon atoms in a glucose molecule that goes through aerobic respiration?   It is converted to glycogen.   It is recycled in the citric acid cycle.   It is turned into starch.   It is converted to pyruvate.   It is released as carbon dioxide.

Why does epinephrine stimulate glycolysis? I know why epinephrine stimulates glycogenolysis which is to release glucose stores. But epinephrine stimulating glycolysis seems counterintuitive as it would synthesize less glucose and more pyruvate?

Which step in glycolysis of glucose need ATP ? Which step in glycolysis of glucose yield ATP?

If the alpha-ketoacid product from the transaminase reaction that uses alanine and alpha-ketoglutarate as substrates goes on to make glucose via the __________ pathway, then the amino acid carbon skeleton is considered to be __________.     ANSWER       citric acid cycle; ketogenic   glycogen synthesis; ketogenic   glycolysis; glucogenic   gluconeogenesis; glucogenic

in steps 3 and 5 of the citric acid cycle, the compounds are shortended by one carbon each time. whst is the form of this one-carbon compound? what happens to it in the body?

Glucose is not the only 6 carbon carbohydrate that can be metabolized. What other 6 carbon carbohydrates can feed into glycolysis? What is it about corn syrup that leads to a “sugar rush”

Breakdown of fatty acids for energy produces two-carbon fragments that are converted to acetyl CoA molecules. How would these molecules be metabolized in aerobic cellular respiration? They would directly enter the energy-yielding phase of glycolysis. They would directly enter the electron transport chain. They would directly enter the citric acid cycle. They would be fermented in the cytoplasm. They would be converted to pyruvate and then undergo pyruvate oxidation upon transport into mitochondria.

The metabolic function of the pentose phosphate pathway is: act as a source of ADP biosynthesis provide intermediates for the citric acid cycle. generate NADPH and pentoses for the biosynthesis of fatty acids and nucleic acids. O participate in oxidation-reduction reactions during the formation of H2O.

How come different fatty acids produce different amounts of ATP during oxidation? What is the primary determinant?

Why do cells use lactic acid fermentation for ATP synthesis during activities such as exercise? Lactic acid provides the cells with additional energy, giving the muscle cells the necessary fuel More oxygen is needed by the muscle cells, which is produced through lactic acid fermentation It creates a larger amount of energy per glucose molecule, which is needed provide the cells with energy It creates ATP more quickly than aerobic respiration to get energy to the cells faster
