Signal Transduction Flashcards
1
Q
What is signal transduction?
A
When the binding of a chemical signal to the receptor causes a conformational change in the protein, causing a specific intracellular response.
2
Q
How are the signals amplified?
A
The activation of the G-proteins or phosphorylation by kinase enzymes.
3
Q
How do hydrophobic signals work?
A
They bind to receptor proteins inside the cell which then activate the transcription of specific genes
