Question

Glucose moves against a concentration gradient,which requires energy; therefore,it is absorbed by ________.
A) simple diffusion 
B) complex diffusion 
C) facilitated transport 
D) active transport 
E) endocytosis

Quizplus · Accepted Answer

Glucose moves against the concentration gradient, so it requires energy to be absorbed. Active transport is the mechanism that uses energy to move molecules against their concentration gradient. Therefore, glucose is absorbed by active transport.
