Each of the following molecules is processed by glycolysis to lactate.How much ATP is generated from each molecule?(a) Glucose 6-phosphate(b) Dihydroxyacetone phosphate(c) Glyceraldehyde 3-phosphate(d) Fructose(e) Sucrose

For each of the following molecules determine how much ATP would be net from aerobic cellular respiration. Show your work. Which of the following produces the most energy? (a) Triglycerides are first digested into glycerol and fatty acids. The catabolism of this triglyceride yields: 1 DHAP molecule, 15 FADH2, 15 NADH, and 18 acetyl- COA. (b) Proteins are first digested into individual amino acids. Deamination removes the amine group from each amino acid. The resulting catabolism produces 12 pyruvate molecules.

How does the cost of storing glucose-6-phosphate (G6P) as glycogen differ from the answer you obtainedin Question 7 if G6P were used for energy in aerobic metabolism?

The glycolytic enzyme glucokinase (in human liver cells) catalyzes the conversion of: glyceraldehyde-3-phosphate into 1,3-bisphosphoglycerate (producing NADH) phosphoenolpyruvate into pyruvate (producing ATP) fructose-6-phosphate into fructose-1,6-bisphosphate (consuming ATP) glucose into glucose-6-phosphate (consuming ATP) 1,3-bisphosphoglycerate into 3-phosphoglycerate (producing ATP)

When a 23 Carbon fatty acid is metabolized, what is the total number of (GROSS) ATP produced ?

Glycogen is the major animal storage polysaccharide, and is a polymer of glucose. a) List ALL the biochemical steps involved in storing GLUCOSE as glycogen b) Give NAME/S of the ENZYMES involved in EACH listed step c) What PULLS the reaction forward? d) Give the NAME of the tissue where these steps occur. (HINT: remember glycogen is branched chain).

What is the net synthesis of ATP when one molecule of fructose-6-phosphate gets converted into 2 molecules of pyruvate?

a) Explain in your own words, under what conditions pyruvate is converted into lactic acid (2pt). b) Does lactic acid fermentation occur in all cells of the body? (0.5pt). c) Explain in your own words your answer to part (b) (1pt) Answers must be in full sentences, include correct grammar and spelling, and contain biological correct information (0.5pt).

The heart cannot convert lactate back to glucose, as the liver does, but instead uses it as a fuel. What is the ATP yield from the complete catabolism of one mole of lactate?

Which cells, liver, muscle, or brain, use the following pathways?(a) Glycolysis(b) Gluconeogenesis(c) Glycogenesis(d) Glycogenolysis
