Question

This plot shows rate of transport as a function of glucose transportation by GLUT1 (the closed circles) with Km = 1.59. Normally humans have a glucose concentration in their blood of about 5mM. According to this plot, about what percentage of glucose transporters would you expect to be actively transporting glucose at 5mM?

1000 GLUT1 GLUT3 800 Km-3.44:0.49 mM 600 400 Km- 1.59+0.18 mM 200 0 2468 10 1 6 D-Glucose] (mM

Answer 1

GLUCOSE: IT IS THE SIMPLE SUGAR HAVING MOLECULAR FORMULA AS C6H12O6

  IT IS MAINLY MADE BY PLANTS DURING THE PROCESS OF PHOTOSYNTHESIS

PHOTOSYNTHESIS CAN BE TAKES PLACE ONLY IN THE PRESENCE OF SUNLIGHT

THERE ARE 10 TYPES TYPES OF GLUCOSE

THE MOST IMPORTANT ARE GLUT1-4,GLUT1,GLUT3,GLUT2,GLUT4

GLUT1 AND GLUT3  LOACTED IN THE PLASAMA MEMBRANE OF CELLS THROUGHTOUT THE BODY

GLUT2 TRANSPORTS HIGH MM VALUE

GLUT4 ARE SENSITIVE AND FOUND IN MUSCLES

THESE TYPES OF GLUCOSE ARE RESPONSIBLE FOR MAINTAING BASIC RATE IN THE BODY

28 TO 29 PERCENTAGE WOULD BE EXPECTED TO TRANSFER ACTIVELY TRANSPORTING GLUCOSE AT 5mM
