Question

Please match the following:

a. an integral membrane protein
b. an example of active transport
c. a peripheral membrane protein may


1) interacts tightly with the interior of the membrane.
2) bind to lipids that are inserted in the interior part of the membrane
3) is the na /k atpase
4) is an antiporter that moves molecules in the same direction
5) is a symporter that moves molecules in opposite directions
6) is an antiporter that moves molecules in opposite direction

Answer 1

Correct matches are: a) An integral membrane protein - interacts tightly with the interior of the membrane, b) An example of active transport - is the Na+/K+ ATPase, and c) A peripheral membrane protein - binds to lipids inserted in the interior part of the membrane.

Step-by-step explanation:

The question asks to match descriptions related to cell membrane proteins and active transport mechanisms. Here are the correct matches:

• An integral membrane protein - 1) interacts tightly with the interior of the membrane.
• An example of active transport - 3) is the Na+/K+ ATPase.
• A peripheral membrane protein - 2) binds to lipids that are inserted in the interior part of the membrane.

Additional information:

• An integral membrane protein spans the entire membrane and can transport molecules across the membrane.
• The Na+/K+ ATPase is an example of an antiporter that performs active transport by moving sodium and potassium ions in opposite directions against their concentration gradients, using ATP as the energy source.
• A peripheral membrane protein is typically found on the inner or outer surface of the lipid bilayer, often performing a specific function for the cell, such as acting as an enzyme.
