Which of the following statements are TRUE? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. A compound is an inhibitor of glyceraldehyde 3-phosphate dehydrogenase. If this compound i where D-glucose was the only substrate there would be an accumulation of those intermediate phosphate to glyceraldehyde 3-phosphate and a depletion of those from 1-3 bisphosphoglycer If in above case the substrate for the liver cells were L-lactate there would be no effect on the co b. intermediates with the exception of the concentration of pyruvate increasing. The only constraint preventing glycolytic intermediates from leaving the cell is that they are all p

Can you please give me more expaination for the question below? I know the equision of Meachile, but I would like to learn what is your theory to draw the graph, I mean why Glycogen is refered as [s] and V max = Product formed glycogen? An experiment was performed to determine the effects of an inhibitor on the breakdown of glycogen by an enzyme. In an accompanying experiment, the inhibitor was added to the glycogen-enzyme suspension and reacted using the same experimental conditions. The data obtained from these experiments is tabulated below. Glycogen (mM) Product Formed Glycogen only (mM/min) Product Formed Glycogen and Inhibitor (mM/min) 0.5 22.6 15.9 1.0 32.1 24.9 1.5 38.1 28.2 2.0 41.2 35.1 2.5 44.7 40.0 3.0 48.5 43.3
Please answer the following question: Answer the following questions about Glygogen Metabolism: (But DON’T Just think about glycogen here!) a. After a carbohydrate-filled breakfast, your blood glucose levels increase. How does glucose affect liver glycogen phosphorylase activity? Briefly explain the direct effect (i.e., not via hormones) glucose has on the enzyme, referring to the structure of the enzyme. b. Imagine you develop a drug that targets glycogen synthase kinase as a treatment for Type 2 diabetes. You need to determine if this drug activates or inhibits glycogen synthase kinase? What effect should the drug have on the phosphorylation state and activity of glycogen synthase? Explain in detail your decision. c. Would protein phosphatase 1 (PP1) have to be active or inactive for this drug to be effective? Explain the rationale for your response; be sure to refer to the function of PP1 in your response.

Consider fructose-1,6-bisphosphatase (FBP) when responding to Parts A, B, and C. When writing your response, please put A, B, or C in front of the answer for each part. NOTE: Each part can be answered in 3-4 sentences.A. State the effect (inhibition OR activation) of insulin signaling on the activity of FBP. Explain why this effect makes sense and make sure you identify the pathway where FBP participates.B. In a type 2 diabetic liver cell, when the blood sugar level is high, will the activity of FBP be HIGHER, LOWER, or THE SAME AS the activity in a nondiabetic liver cell under the same conditions? Explain your reasoning.C. Now think about the insulin and glucagon signaling pathways that control activity of FBP. When a nondiabetic liver cell is exposed to low blood sugar, indicate one specific way the insulin or glucagon signaling pathway could be disrupted so that the activity of FBP is not controlled correctly. Then, explain the reasoning for your answer.
