Answer:
calcium channel close.
Explanation:
In action potential there is phase 0, phase 1, phase 2, phase 3 and phase 4. In phase 3 of action potential there is a rapid repolarization phase in which calcium channels remain closed but potassium channels remain open and continuous outward movement or leakage of positive ions causes the outside environment positive and membrane potential goes to negative charge that is -85mV to -90mV
Answer: All of the above (I, II, III, IV)
Explanation:
The Insulin receptor is a large protein that binds to insulin and passes its message into the cell. When insulin binds to the receptor, it causes a change in shape that is propagated inside the cell, which results to MAPK activation, which regulates gene expression via Fos, Jun and Myc, PI3K activation leading to an increase in glucose transport, High affinity binding of SH2 domains to phosphorylated tyrosines and Autophosphorylation resulting in activation of tyrosine kinase.
A bloodborne pathogen training class might include Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) they are the most common bloodborne pathogens from which health care workers are at risk
