Glycolisis is process that is reversible, meaning that any product that is being formed can easily go in the opposite direction and cause a sugar to rebuild itself. Once the end product of hlycolysis moves into the mitochondrion the products cannot leave the mitochondrion and enter glycolysis again. Amino acids, depending on the type, can be broken down into the following products: pyruvate, acetyl Co A, Glyceraldehyde 3 phosphate PGAL, alpha ketoglutarate, fumarate and others. For each of those products, indicate where they would enter intothe process of cellular respiration. Can any of those products form a glucose molecule, in other words, can any of the amino acids become a glucose in our cells, explain.

A cell is grown on minimal media containing only 3-phosphoglyceric acid as a source of carbon and energy. What is the most likely place this compound would enter the metabolic cycle? Group of answer choices Glycolysis Conversion of Pyruvate to Acetyl-CoA The TCA Cycle The Electron Transport Chain

Like many fruits, apples contain not only fructose and glucose, but also sucrose, a dimerof fructose and glucose. Synthesizing sucrose is endergonic and so not spontaneous. Onerole of ATP is to facilitate reactions that would not occur spontaneously. The threephosphate groups are electron rich and tend to repel each other. Therefore, ATP is a bitlike a compressed spring, ready to kick off one phosphate group releasing energy.Consider: Fructose + glucose --> Sucrose delta G= 6.4 kcal/mol ATP --> ADP + Pi delta G= -7.3 kcal/mol a. Draw a simple energy diagram (including the relative energy of the reactants andproducts) that shows why the sucrose synthesis reaction doesn’t occur spontaneously. b. How could having these two reactions occur at the same time help with sucroseproduction? c. Draw the energy diagram that shows all the reactants and products for the combinedreactions. d. What is delta G for the combined reactions? e. Name a few of the biological processes in the body that…

All of the following statements about glucose are true except: Glucose is metabolized in the cytoplasm of prokaryotic organisms. On a low-carb diet, keto acids from glucogenic amino acids will be used to synthesize glucose. Glucose is metabolized in the mitochondria of mature red blood cells. Under non-starvation conditions, the brain relies exclusively on glucose as its fuel source.

Which of the following accurately describes the enzymatic regulation of glycolysis? Glycolytic enzymes maintain a steady-state [ATP]; ATP activates the pathway, ADP and AMP inhibit it. Glycolytic enzymes maintain a steady-state [ATP]; ADP and AMP activate the pathway, ATP inhibits it. Glycolytic enzymes maintain ATP hydrolysis at equilibrium (AG = 0); ATP activates the pathway, ADP and AMP inhibit it. Glycolytic enzymes maintain ATP hydrolysis at equilibrium (AG = 0); ADP and AMP activate the pathway, ATP inhibits it.
