Cell signalling

Question 1

Stages of cell signalling

Answer 1

1. Ligand-receptor interaction
2. Signal transduction
3. Cellular response

Question 2

Ligand-receptor interaction

Answer 2

1. the ligand/signal molecule is complementary in shape to a specific binding site on the receptor and attaches itself there
2. the binding of the ligand to the receptor induces a conformational change in membrane-bound receptor

3.
