**Core Concept**
The small intestine plays a crucial role in the absorption of glucose, a vital process for maintaining blood glucose levels. This process involves the coordinated action of enzymes, transport proteins, and specific receptors. The intestinal absorption of glucose is facilitated by a sodium-glucose cotransporter.

**Why the Correct Answer is Right**
The correct answer is facilitated diffusion via the sodium-glucose cotransporter 1 (SGLT1). SGLT1 is a membrane-bound protein that spans the intestinal epithelial cell membrane and is responsible for the uptake of glucose from the intestinal lumen into the enterocytes. This process is coupled to the movement of sodium ions down their concentration gradient, driven by the sodium-potassium pump. The sodium-glucose cotransporter 1 has a high affinity for glucose and is responsible for the initial uptake of glucose from the intestinal lumen.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to the absorption of glucose in the intestine.
**Option B:** This option refers to the absorption of amino acids, not glucose.
**Option C:** This option is incorrect as the primary mechanism of glucose absorption is facilitated diffusion via the sodium-glucose cotransporter 1, not active transport.

**Clinical Pearl / High-Yield Fact**
The sodium-glucose cotransporter 1 is a high-affinity transporter that plays a critical role in the absorption of glucose from the intestinal lumen. The activity of this transporter is influenced by the concentration of sodium ions and glucose in the intestinal lumen.

**Correct Answer: C. Facilitated diffusion via sodium-glucose cotransporter 1.**
