Final answer:
Glucose is primarily absorbed in the small intestine via facilitated diffusion, using carrier proteins to move down the concentration gradient without using energy. Therefore, the correct answer is Facilitated Absorption (B).
Step-by-step explanation:
The absorption of glucose occurs through several mechanisms in the small intestine. One of the primary ways monosaccharides like glucose are absorbed is through facilitated diffusion. In facilitated diffusion, glucose molecules move down their concentration gradient through carrier protein channels in the cell membrane.
This process does not require energy (ATP) and allows glucose to passively move from an area where it is more concentrated to an area where it is less concentrated. Glucose absorption can also occur through active transport, where glucose is moved against its concentration gradient into the cell, a process that requires energy.
Given the specific mechanisms mentioned in the question and the information provided, glucose is absorbed via Facilitated Absorption (B). This is because the glucose utilizes carrier proteins to passively move through the cell membrane without the expenditure of energy.
