5 0

Answer:

Almost all calcium in the body is stored in bones and teeth, giving them structure and hardness. Your body needs calcium for muscles to move and for nerves to carry messages between your brain and every part of your body.

Sodium-Potassium Pump

Three sodium ions bind to intracellular sites on the sodium-potassium pump.

A phosphate group is transferred to the pump via the hydrolysis of ATP.

The pump undergoes a conformational change, translocating sodium across the membrane.

The mechanism whereby an enveloped virus leaves a host cell is called
Levart [38]

Answer:

Release or egress

Explanation:

Virus can reproduce only within a host cell, this cycle of infection begins with the <em>attachment</em>, where the virus attaches to a specific receptor site on the host cell, after this comes the<em> entry,</em> in the case of enveloped virus, the envelope can fuse directly with the cell membrane to enter the cell, they can also enter through endocytosis. After entering the cell the virus initiates a <em>replication  and assembly </em>mechanism depending on its genome, finally, the last stage of viral replication is the <em>release or egress </em>of the new virions produced in the host organism, some viruses can be released when the host cell dies, but some can leave infected cells by budding through the membrane without directly killing the cell.

I hope you find this information useful and interesting! Good luck!
