Westkost [7]3 years ago
6 0

Answer:

The correct option is : a. causing threshold to be reached more quickly      

Explanation:

Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.

It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.

Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>

<h3>What is mitomycin?</h3>

A medication may have side effects in addition to the ones that are intended. Even though not all of these side effects are likely to occur, if they do, medical treatment may be required while consuming mitomycin.

Additionally, due of how cancer medications affect the body, there is a potential that they could result in other side effects that could not show up for several months or even years after the medication has been taken. Some forms of cancer may be among these unintended consequences.
