During exercise, how does glucose enter the muscle cell independent of insulin?
?Which of the following events does NOT occur during anaerobic respiration of glucose? ? A. Muscle cell produce lactic acid B. Carbon dioxide is produced C. Milk bacteria produce lactic acid D. Energy is not produced E. Germinating seeds produce alcohol.
why does glucose enter and not exit the cell ?
Provide some examples. How does the concentration of glucose effect insulin secretion?
thermal physics question A muscle can be thought of as a fuel cell that produces work from the metabolism of glucose CeH1206 602-6C02 6H20 Relevant data on the reactants and products are tabulated below: H (kJ/mol) -1273 0 | Δ/G (kJ/mol) -910 0 -394.4 237.1 | Glucose O2 (g) CO2 (g393.5 H2O (1) S (J/Knol) 212 205 214 70 -285.8 5. Assuming ideal operation at room temperature, how much work could your muscles 6. Still assuming ideal operation, will heat...
. Skeletal muscle cells produce glucose carriers (GLUT 4 transporters). Rather then having these transporters continually on their surface, they store them inside vesicles within the cell. During exercise (muscular contraction), these vesicles fuse with the plasma membrane of the cell, inserting the transporters into the membrane. This allows glucose to enter the cell by passive transport. Which of the factors that affect simple diffusion has been altered in this example?
3. During exercise, skeletal muscle also maintains a glucose supply through glycogen degradation. Determine the energetic cost of maintaining glucose to the muscle by this mechanism, taking into account the costs of storage and utilization. OPTIONS ARE: -6 -4 -2 0 +2 +4 +6 Pathway ATP generated ATP/GTP consumed Net ATP/GTP Glucose -> glycogen glycogen -> glucose Net ATP/GTP
diagram how plasma glucose levels are sensed by the pancreas to release either insulin or glucagon to maintain plasma glucose levels at relatively stable levels. At a minimum, your diagram or illustration should include the following terms: endocrine pancreas, islets, alpha-cells, beta-cells, glucose, GLUT2, GLUT4, insulin, glucagon, liver, skeletal muscle, and adipose tissue.
explain the different biological roles of insulin on the podocyte , muscle cell, and neurons include the mesangial cells, glomerular endothelial cells, proximal tubular cell , distal tubular cell
6) In unstimulated muscle cells, the glucose transporter Glute is present in the membrane of endosomes. Upon stimulation of these cells with insulin, the endosomes fuse with the plasma membrane, thereby depositing Glut4 in the plasma membrane, where it serves to transport glucose into the cells. In order for insulin to elicit this change in Glute localization, insulin must bind to its receptor, present in the plasma membrane of some cells. To determine if a stem cell line can be...
During exercise glucose consumption increases to 60 :mol min-1 100 g-1. Assume arterial [glucose] does not change. Blood flow increases to 0.60 mL min-1 g-1. G. What is the venous concentration of glucose during exercise?
