CHOOSE THE CORRECT LETTER When glycogen is synthesized in both the liver and muscle, all the following are true, EXCEPT A.Glucose is transferred from UDP-glucose to a growing glycogen molecule by glycogen synthase.B. Phosphoglucomutase converts glucose 6-phosphate to glucose 1-phosphateC. Glucose 6-phosphate is converted to glucose by a phosphatase.D.Glucose 1-phosphate is activated by UDP-glucose pyrophosphorylase to produce UDP-glucose and PPi.
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
CHOOSE THE CORRECT LETTER What is the product of glucose metabolism in skeletal muscles in aerobic conditions?A. Acetyl-CoAB. glycogenC. lactateD. acetaldehyde
Can you please pick the right answer in each parentheses? Sphingolipids are synthesized from ["palmitoyl-CoA", "cholesterol"] and have a diversity of biological functions that include ["signaling", "both structural element of myelin and signaling", "structural element of myelin sheath"]. Fatty acid synthesis occurs in the ["cytoplasm", "endoplasmic reticulum"] and the delivery of ["acetyl-CoA unit as building blocks", "pyruvate"] occurs via the ["citrate shuttle", "pyruvate transporter"].
fill in the blank with the correct term and explain why that term fits best to the following , one reason to phosphorylate glucose is to increase the number of available noncovalent interactions between the phosphorylated sugar and the enzymes, thus increasing the ____________.
Which carbons of glucose will be incorporated into Palmitic acid by the Fatty Acid Synthase? Multiple answers:Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation...SHOW MORE a Carbon 1 b Carbon 2 c Carbon 3 d Carbon 4 e Carbon 5 f Carbon 6 g All carbons will be incorporated. h No carbons will be incorporated.
CHOOSE THE CORRECT LETTER Which enzyme assists the transition of an activated fatty acid through the inner membrane of the mitochondria?A. acyl-CoA synthetaseB.carnitine transferaseC. phospholipaseD. lipase
Fill in the blanks and explain the relationship between the paired words/phrases a. methotrexate: dihydrofolate reductase; ___________: thymidylate synthase b. __________: aspartate; purine: glycine
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.
Identify the enzyme that carry out the below reaction and denotes the nature of the enzyme? UDP-galactose + N-acetylglucosamine ~ UDP + N-acetyllactosamine
Which of the following is NOT involved in the activation of glucose for glycogen synthesis? A. Phosphorylation of glucose by hexokinase to glucose-6-phosphate. B. Isomerization of glucose-6-phosphate to fructose-6-phosphate by phosphohexose isomerase. C. Two-step phosphoryl group transfer by phosphoglucomutase. D. Attachment of glucose-1-phosphate to UDP.
What is an example of a biomolecule that interacts with Insulin? Please give a detailed explanation of that molecule's structure as well!
