How is a “committed step” defined in the context of a metabolic pathway and why are they important? Which steps and/or enzymes are involved in the committed steps in the Krebs Cycle? What are the possible implications of these steps were deregulated?
create a single illustration that will interrelate or link the two opposing pathways, the Glycogenesis and Glycogenolysis. I want you to include the enzyme in each step and include some important by-products as well. From the illustration, I want you to encircle the intermediate molecule to highlight the link between the two processes. Aside from the illustration, I want you to compare and contrast the two pathways in terms of function, number of reaction steps, and usage of UTP. You can tabulate this part to make it simpler.
The following reaction would most likely be catalyzed by an enzyme of which class?
sucrose + H2O → glucose + fructose

- a) Describe the three irreversible reactions of the Citric Acid Cycle. Ensure to indicate their purpose/role, the substrates and products, the enzyme involved, and any significant features of the reaction. b) Why are these reactions considered irreversible (why can't they be reversed)? c) Using one of the reactions as an example, explain why it is important for the cell that the reaction is irreversible.arrow_forwardFor a lot of enzymes that work on fatty acids, the rate determining step is the release of the product from the active site. This means that the activation energy for product release is much higher than the free energy of catalysis. What enthalpic or entropic contributions would make the activation energy for product release so high and explain?arrow_forwardWhich of the following is a product of the first stage of the pentose phosphate pathway? choices:arrow_forward
- What type of enzyme regulation is the most readily (quickly) reversible?arrow_forwardYou have the following pathway: If an isolated liver cell runs out of glucose, the cell will break down glycogen into Glucose-1-Phosphate (Glucose-1-P). The isolated liver cell will then use the enzyme phosphoglucomutase to convert Glucose-1-P to Glucose-6-P, which can enter glycolysis. If you remove all glucose and add a drug that inhibits phosphoglucomutase, which molecule will most likely accumulate in this system? A. Glucose B. Glucose 1 phosphate C. Glucose 6 phosphate D. Lactate E. CO2arrow_forwardWhy is the enzyme-catalyzed introduction of carbon–carbon double bonds into fatty acids called an electron transport system?arrow_forward
- a) Identify three differences between glycolysis and gluconeogenesis. b) Why should we avoid just seeing these processes of reversals of each other?arrow_forwardIn glycogenolysis, in the reaction: glu-6-phosphate to glucose. What reaction is involved? Name the enzyme. Identify the two pathways where this enzyme is used.arrow_forwardThe break down of sugar occurs in biological cells. It goes through multiple stages to produce energy that cells use. One series of reactions during this process is call the citrus acid cycle. Discuss how you could either speed up or slow down the degradation of glucose through the citrus acid cycle? (Hint: look at the citrus acid cycle and choose one step)arrow_forward
- Von Gierke’s disease is also known as glycogen storage disease type I. Patients with von Gierke’s disease lackglucose 6-phosphatase activity. Two prominent symptoms of this disorder are fasting hypoglycemia and lactic acidosis (elevated lactate levels in the blood), especially during strenuous exercise. Explain why these symptoms occur. What chemical reaction does this enzyme catalyze? Which pathways involve this enzyme? Lacking thisthe enzyme will cause impairment of which pathways?• Pls consider what pathways are affected by Von Gierke’s disease.
