In animals, glucose is absorbed from the gut into intestinal cells against its concentration of gradient. This one-way process requires energy to work. Which of the following best describes how glucose is absorbed into intestinal cells? A. By osmosis
B. By diffusion
C. By a buffer
D. By active transport

Glucose is absorbed through the intestine by a transepithelial transport system initiated at the apical membrane by the cotransporter

Explanation:

if im wrong ill give you your points

D. By active transport

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
