10. INTERPRET DATA GLUT 4 is a glucose transporter that functions in adipose (fat) cell plasma membranes. An analysis of adipose cells exposed to insulin showed that a single cell could import glucose at a maximum rate of about 1×108 molecules/second. Under the same conditions, unstimulated cells could only transport a maximum of about 1×107 molecules/second. What does this finding tell you about the relative number of GLUT 4 transporters functioning in the plasma membranes of stimulated versus unstimulated cells?

Glucose transporter (GLUT) isoforms move glucose in and out of the cell GLUTS respond to the glucose equilibrium concentrations. Use your knowledge of enzyme catalysis
and lonetics to predict which of the following correctly rank the steps in glucose transport by GLUT1?
1. Glucose binding results in a conformational change, opening the binding site on the opposite side of the membrane
11. Glucose binds to the transporter on one side of the membrane
II. The transporter reverts to initial conformation
IV. The glucose disassociates

is this stement false?
Intracellular concentrations in resting muscle are as follows: Fructose-6-phosphate (1.0 mM)Fructose-(1-6)-bisphosphate (10.0 mM)AMP (0.1 mM)ADP (0.5 mM)ATP (5.0 mM)Pi (10.0 mM)Under the above conditions the Phosphofructokinase reaction in muscle is more exergonic than under standard conditions.

Explain why or why not.1 The role of ATP hydrolysis in actin polymerizationis similar to the role of GTP hydrolysis in tubulin polym-erization: both serve to weaken the bonds in the polymerand thereby promote depolymerization.2 Motor neurons trigger action potentials in musclecell membranes that open voltage-sensitive Ca2+ channelsin T tubules, allowing extracellular Ca2+ to enter the cyto-sol, bind to troponin C, and initiate rapid muscle contrac-tion.3 In most animal cells, minus-end directed microtu-bule motors deliver their cargo to the periphery of the cell,whereas plus-end directed microtubule motors delivertheir cargo to the interior of the cell.arrow_forward
- Calculate the number of cells in the body of an average 68-kg (150-lb) adult. (This will only be accurate to about 1 part in 10 but should give you an idea how scientists estimate this commonly quoted number.) Assume all cells are spheres 20 m in diameter. The volume of a sphere can be determined by the equation v=4/33. (Hint: We know that about two thirds of the water in the body is intracellular and the density of cells is nearly 1 g/mL. The proportion of the mass made up of water is about 60%.)arrow_forwardPlz answer asap.arrow_forwardK+ [Select] [Select] A Na+ Primary active transport is being shown by transporter [Select] which uses [Select] ATP [Select] B The transported molecules in this mechanism are being moved [Select] to move Glucose active transport is being shown by transporter [Select] which uses the gradient.

- Table K₁ (T1) Vmax (T1) Kt (T2) Vmax (T2) 1 1.12 mM 125 nmole/min None of the above. 3.0 mM 130 nmole/min Based on these values, what are your conclusions? O T1 is most likely a cell that expresses a high affinity transporter for glucose. T2 is most likely a cell that expresses a high affinity transporter for glucose. T1 must be a cell expressing the insulin-dependent glucose transporter. Each transporter has a similar Vmax and therefore both T1 and T2 are the same cell type.arrow_forwardPlease asaparrow_forwardAnswer pleasearrow_forward
