Chemical Signalling 1
Whats another name for a signalling molecule that binds to a receptor?
What type of receptor binds to insulin?
Tyrosine Kinase
chemical used by a neuron to transmit an impulse across a synapse to another cell
Neurotransmitter
The inside of the membrane becomes less negative (more positive), by the movement of 3 sodium ions in and 2 potassium ions out. What is this process called?
Depolarization
What is the largest bone in the human body?
Femur
Name one way a receptor is similar to an enzyme and one way they are different
Similar: (Binding site/Active site).
Different: Ligand remains unchanged.
What do we call a sequence of interactions initiated by the ligand binding to the receptor
Transduction pathway
What's the resting potential? (give a number)
-70mV
Occurs during repolarisation where the membrane becomes more negative than usual and leads the membrane to return to its resting potential.
Hyperpolarization
