K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [C]
## CONCEPT FRAMEWORK
	**Primary Concept**: Facilitated diffusion of glucose
	**Related Topics**: Membrane transport mechanisms, active transport, diffusion
	**Prerequisites**: Basic understanding of cell biology and transport processes
## SOLUTION PATHWAY
**Given Information**:
		- Glucose is a polar molecule and cannot easily pass through the lipid bilayer of cell membranes.
		- Cells require glucose for energy production.
**Method & Steps**:
	1. Glucose transport relies on specific proteins in the cell membrane.
		Reasoning: Glucose cannot diffuse freely due to its polarity and size.
		Formula/Rule: Transport proteins are required for polar substances.
	2. Identify the type of transport proteins involved.
		Working: Glucose is transported via carrier proteins known as glucose transporters (GLUT).
		Key Point: These proteins facilitate the movement of glucose down its concentration gradient.
	3. Conclude the specific mode of transport for glucose.
		Result: Glucose enters the cell via facilitated diffusion using carrier proteins.
		Verification: This process does not require energy as it moves along the concentration gradient.
## OPTION ANALYSIS
[A] :x: Simple diffusion does not apply as glucose cannot pass through the lipid bilayer easily.
[B] :x: Facilitated diffusion using channel proteins is not accurate since glucose uses carrier proteins, not channels.
[C] ✓: Facilitated diffusion using carrier proteins is the correct answer, as glucose transporters assist in moving glucose into cells without energy.
[D] :x: Active transport is incorrect as glucose transport does not require ATP when moving down its gradient.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing facilitated diffusion with active transport: Remember that facilitated diffusion does not require energy, while active transport does.
		2. Assuming all transport happens through channels: Not all polar molecules utilize channel proteins; glucose specifically uses carrier proteins.
	**Quick Tips**:
		1. Remember the acronym GLUT for glucose transporters to help recall the facilitated diffusion mechanism.
		2. Visualize the cell membrane as a barrier that requires assistance (proteins) for polar molecules to cross.
