- Place the steps of glycolysis in the order that they occur. Last step Answer Bank Glucose is phosphorylated by hexokinase. Glyceraldehyde-3-phosphate is converted to 1,3-bisphosphoglycerate. Aldolase cleaves the six-carbon sugar into two three-carbon sugars. Phosphoenolpyruvate is converted to pyruvate. 3-Phosphoglycerate is formed. Fructose-6-phosphate is phosphorylated by phosphofructokinase. First steparrow_forwardThe rate-limiting step is a metabolic pathway is the slowest step which determines the overall rate of the other reactions in the pathway. In glycolysis, the rate limiting step is a phosphorylation reaction where phosphofructokinase (PFK-1) catalyzes the reaction fructose-6-bisphosphate -> fructose-1,6-bisphosphate, the same step in gluconeogenesis. Select one: The statement is FALSE. The statement is TRUE.arrow_forwardPlease do both.arrow_forward
- What is the name of the enzyme that converts glycerol to glycerol-3-phosphate?arrow_forwardHow many electron carrier molecules (both NADH and FADH₂) are made per glucose put in to glycolysis? How many electron carrier molecules (both NADH and FADH₂) are made per pyruvate put in to the Krebs Cycle? How many electron carrier molecules (both NADH and FADH₂) are made by the Krebs Cycle per glucose consumed by the organism? How many electron carrier molecules in total (both NADH and FADH₂) have been made from a single glucose after both glycolysis and the Krebs Cycle? How many electrons are being carried from glucose at this point (Hint: 2 per molecule)?arrow_forwardKinetic versus thermodynamic. The reaction of NADH with oxygen to produce NAD+NAD* and H2OH2O is very exergonic, yet the reaction of NADH and oxygen takes place very slowly. Why does a thermodynamically favorable reaction not occur rapidly?arrow_forward
- Which statement is TRUE regarding ketone bodies? O Ketone bodies are only formed during times of starvation. Excess acetoacetate produced during ketone body production is mostly exhaled. O Ketone bodies can easily travel from one tissue to another in the body due to the preser Coenzyme A. O Ketone bodies tend to be formed when oxaloacetate concentrations are high. O Ketone bodies can be used as a source of acetyl-CoA in target tissues when blood glucosarrow_forwardWhat compound is produced during strenuous exercise, when the muscles are depleted of oxygen? pyruvate carbon dioxide lactate ethanol NADPHarrow_forwardRigor mortis, the stiffening of muscles. after death is due to the depletion of intracellular ATP.

The conversion of pyruvate to lactate would seem to be an unnecessary step, since this process does not result in any further release of energy. Explain the necessity for the production of lactate as the endpoint for anaerobic glycolysis.arrow_forward
