Read each question carefully and provide detailed answers based on your understanding of active transport.
1. Which of the following is a key characteristic of active transport?
Movement of substances down their concentration gradient
Does not require energy input
Requires ATP hydrolysis
Facilitated by aquaporins
2. The sodium-potassium pump is an example of:
Simple diffusion
Secondary active transport
Primary active transport
Osmosis
3. Active transport moves molecules from an area of concentration to an area of concentration.
4. The energy for active transport is typically supplied by .
5. active transport uses the energy stored in an electrochemical gradient.
6. Differentiate between primary and secondary active transport, providing an example for each.
7. Explain the role of carrier proteins in active transport.
8. Active transport can occur without the involvement of membrane proteins.
True
False
9. Observe the diagram below, which illustrates a type of membrane transport. Based on your knowledge, explain why this diagram represents active transport.
