Cell Signalling

Question 1

Why do cells need to communicate?

Answer 1

To control processes inside the body and to respond to changes in environment.

Question 2

How do cells communicate?

Answer 2

Using messenger molecules.

Question 3

What are the 3 steps in cell communication via messenger molecules?

Answer 3

1) One cell releases a messenger molecule.
2)This molecule travels to another cell.
3)This is detected by the cell as it binds to a receptor on its cell membrane.

Question 4

What type of receptors play an important role in cell signalling?

Answer 4

Cell membrane Receptors.

Question 5

What are the steps in cell signalling? Including Cell membrane Receptors.

Answer 5

1) proteins in membrane act as receptors form messenger molecules.
2) Receptor proteins have specific shapes.
3)Different cells have different types of receptors.
4)A cell that responds to a particular messenger molecule is a target cell.

Question 6

How do drugs and cell membrane receptors interlink?

Answer 6

Drugs bind to cell membrane receptors which is how they work.They either trigger a response in the ell or block the receptor and prevent it from working.
