A male client with a diagnosis of type 1 diabetes mellitus is experiencing hyperglycemia because he lacks sufficient insulin to increase the availability of glucose transporters in his cell membranes
Consequently, his cells lack intracellular glucose, and it accumulates in his blood. Which of the following processes would best allow glucose to cross his cell membranes?
A) Facilitated diffusion
B) Simple diffusion
C) Secondary active transport
D) Endocytosis
Ans: A
Feedback:
Transport molecules perform facilitated diffusion, in which one substance carries another substance across a cell membrane. Simple diffusion does not require a transport molecule. Glucose does not cross the cell membrane by secondary active transport or endocytosis.
