Amutation in glut4 changes the kt value from 5 mm (wild type) to 3 mm (mutant). the velocity of glucose entry into a mutant cell would be higher than a cell expressing the wild type version at a blood glucose concentration of 5mm.
a) true.
b) false.

 The correct answer is :  A) TRUE.

Explanation:  GLUT 4 is a protein that transports genetically encoded glucose, is located in adipocytes, skeletal muscle and cardiac muscle, is encoded by a gene on chromosome 17. It has a Km for glucose of 5 mm. When there is no adequate stimulus, most of the GLUT 4 is stored in intracellular vesicles.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
