what is the effects of muscle glycogen phosphorylase deficiency. abnormally high levels of skeletal muscle glycogen. skeletal muscle glycogen with an abnormally high degree of branching.  a deficiency of skeletal muscle glycogen. decreased production of lactate under conditions of strenuous activity.  an inability to import glucose into the cell.

Blood sugar homeostasis: Indicate the order of events that will happen following blood glucose increase after a meal. Increased blood glucose 1 2 3 4 LO 5 6 :::: Glucose transport via GLUT4 Glucose transport into pancreatic cells Insulin binds to insulin receptor Insulin release from pancreatic beta-cells Second messenger signaling pathway is activated GLUT4 moves to plasma membrane Decreased blood glucose AND muscle makes ATP and glycogen

Normally, when blood glucose level increases (e.g. after a meal), the islet cells in the pancreas secrete insulin. When insulin molecules bind to insulin receptors on the surface of a muscle cell, the receptors become activated, initiating a signaling pathway which eventually results in the increase in the number of passive glucose transporter on the muscle cell surface thus increases the uptake of glucose into the cell and decrease blood glucose level. Indicate whether the following conditions/practice will likely lead to diabetes (mark Yes or No). [Select] degeneration of islet cells [Select] [Select] [Select] a mutation in the insulin receptor that increases its kinase activity ✓ exercise a mutation in the insulin receptor that prevents dimerization

Insulin signals activate all of the following enzymes except: Phosphoinositide 3-kinase (PI3K) Glycogen synthase kinase 3 (GSK3) Protein kinase B (PKB; or Akt) All of the above enzymes are activated by insulin signals   Citrate move in and out of mitochondria via a specific transport protein. What would happen if aninhibitor completely inhibited this transport system? Fatty acid biosynthesis would slow down Ketone body synthesis would slow down Both A and B Neither A nor B
