Glucose is transpoed in pancreas through whichreceptor ?
**Core Concept**
Glucose transport in the pancreas is mediated by specific glucose receptors that regulate the uptake of glucose into pancreatic cells, particularly beta cells. This process is crucial for insulin secretion and glucose homeostasis. The glucose transporter responsible for this function is a type of facilitated diffusion receptor.
**Why the Correct Answer is Right**
The correct glucose receptor in the pancreas is the glucose transporter 2 (GLUT2). GLUT2 is a high-capacity, low-affinity glucose transporter that allows glucose to enter pancreatic beta cells. This transporter is essential for glucose sensing and insulin secretion. When glucose binds to GLUT2, it triggers a signaling cascade that ultimately leads to insulin release.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify a known glucose receptor in the pancreas. While there are several glucose transporters, not all of them are present in pancreatic cells.
**Option B:** This option is incorrect because it refers to a glucose transporter found in the liver, not the pancreas. GLUT2 is indeed found in the liver, but it is not the primary glucose receptor in pancreatic beta cells.
**Option C:** This option is incorrect because it does not accurately describe a glucose receptor in the pancreas. There is no widely recognized glucose receptor by this name.
**Option D:** This option is incorrect because it does not specify a known glucose receptor in the pancreas. While there are several glucose transporters, not all of them are present in pancreatic cells.
**Clinical Pearl / High-Yield Fact**
Remember that GLUT2 is a bidirectional glucose transporter, meaning it can transport glucose in both directions across the plasma membrane. This property is essential for glucose sensing and insulin secretion in pancreatic beta cells.
**Correct Answer:** C. GLUT2
