How does the sodium potassium pump work in our cells?

1 answer:

4 0

In human cells,the hydrolysis of ATP to form energy needed by the cell is the main utilizer of the Sodium potassium pump.The process involves the movement of Sodium ions and potassium ions across the cell membrane through active transport mechanism.Here,an enzyme called Na+/K+- AT phase is utilised to maintain a larger excess of Na+ions outside the cell and a corresponding large excess of K+ions on the inside.

This sodium potassium pump is important because it contribute to action potential produced by nerve cells.

Answer:

1. Flower-The biological function of a flower is to affect reproduction, usually by providing a mechanism for the union of sperm with eggs.

2. leave-Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food

3. Stem-The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots

4. Roots-Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels ( xylem )

Which hormone does the sympathetic nervous system release to increase heart rate.

sertanlavr [38]

The sympathetic nervous system releases hormones known as catecholamines which increase the heart rate.

<h3>What is a heart rate? </h3>

it is the number of contractions of the heart per minute.

<h3>What are catecholamines?</h3>

These are the neurotransmitters that have a catechol and a side chain that is an amine.

<h3>Which catecholamines are released by the sympathetic nervous system?</h3>

Epinephrine and norepinephrine are the catecholamines that are released by the sympathetic nervous system to increase the heart rate.

<h3>Where are these hormones released?</h3>

These hormones are released in the blood.

<h3>How does this hormone increase the heart rate?</h3>

"These hormones are released at the neuromuscular junction of the cardiac nerves."
"They shorten the repolarization period."
This speeds up the rate of depolarization and contraction and thus the heart rate is increased.
