Question

Active transport differs from facilitated transport as the former

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Differences between active and facilitated transport
	**Related Topics**: Membrane transport, Cellular energy, Protein function
	**Prerequisites**: Basic understanding of cell membrane structure and transport mechanisms
## SOLUTION PATHWAY
**Given Information**:
	*  Question asks for the key difference between active and facilitated transport.
	*  Options provide potential distinguishing characteristics.
**Method & Steps**:
	1.	**Recall the definition of active transport:** It moves molecules against their concentration gradient, requiring energy.
		Reasoning: Active transport needs energy, usually in the form of ATP, to overcome the concentration gradient.
		Formula/Rule: N/A
	2.	**Recall the definition of facilitated transport:** It moves molecules down their concentration gradient, aided by membrane proteins, without requiring direct energy input.
		Working: Facilitated transport is passive, relying on the concentration gradient.
		Key Point: It uses proteins but doesn't directly use ATP.
	3.	**Compare the options:** Identify the option that aligns with the requirement of energy for active transport.
		Result: Option D, 'Is ATP dependent', correctly describes a key difference.
		Verification: Active transport requires ATP, while facilitated transport does not.
 ## OPTION ANALYSIS
[A] :x: Both active and facilitated transport require special membrane proteins.
[B] :x: Both active and facilitated transport can be highly selective.
[C] :x: Both active and facilitated transport can be affected by protein inhibitors.
[D] ✓: Active transport requires ATP, while facilitated transport does not.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing the requirement of membrane proteins with energy dependence.
			[How to avoid]: Remember that both transports use proteins; the key difference lies in ATP use.
		2.[Error 2]: Misunderstanding the direction of transport relative to the concentration gradient.
			[How to avoid]: Active transport moves against the gradient, facilitated moves with it.
	**Quick Tips**:
		1.[Helpful shortcut]: Think of 'active' as 'requiring activity' which means energy.
		2.[Memory aid]: ATP = Active Transport Power.
