5 0

Since you left off the choices, I have to just present the facts of what occurs first in the nerve impusle. The first thing that will is happen is the sodium ios will move to the inside of the nueron. The second step is the potassium ions will move to the inside of the neuron. After those move into the nueron, calcium will then move into the nueron. Both the sodium and potassium have 1 postive charge. While the calcium ion has 2 positive charges.

Chronic Myelogenous Leukemia (CML) is a type of cancer that is caused by a specific chromosomal alteration that leads to the ina

Degger [83]

A drug used to treat CML, imatinib, binds to the active site of Abl kinase. Why does this drug work to treat this type of cancer?

B) By binding to the active site, the drug prevents the ability of Abl kinase to bind to its substrate.

Imatinib works against CML by binding close to the ATP binding site of bcr-abl. The binding results to the locking in of the bcr-abl to a closed or self-inhibited conformation and inhibiting the enzyme activity of the protein semi-competitively.
