Answer:
Cytokinesis
Explanation:
Cytokinesis happens after mitosis. It is the final division to create two new cells. In this phase, the cytoplasm divides and two complete daughter cells are created. These two new cells have genetic information that is identical to the parent cell from which they originated.
The
molecules which move large molecules into and out of the cell are known as
membrane transport proteins-transporters.
<span>Their
function is to move all the molecules that are not capable to pass via passive
diffusion. So, transporters are involved in the movement of ions, small
molecules, or macromolecules, such as another protein, across a membrane.
Transporters are integral transmembrane proteins and can be categorized as channels
or carriers. These proteins assist in the movement of molecules by facilitated
diffusion or active transport.</span>

A protein kinase that is specific to the amino acids serine and threonine is known as a mitogen-activated protein kinase (MAPK or MAP kinase; also known as a serine/threonine-specific protein kinase).
<h3>Mitogen-activated protein kinase :</h3>
A small number of cell surface receptors can ultimately generate a large intracellular response due to activation of kinase cascades.
In order to trigger an appropriate physiological response, such as cellular proliferation, differentiation, development, inflammatory reactions, and death in mammalian cells, MAPK pathways relay, amplify, and integrate information from a variety of stimuli.
Tyrosine phosphorylation, specifically numerous tyrosines on each RTK in the dimer, is how cross-linking triggers the tyrosine kinase activity in these RTKs. The term "cross-phosphorylation" refers to this action.
The activation of a MAPKKKK or MAPKKK by stimulation of plasma membrane receptors is the initial stage of signal transduction. The MAPKKK then phosphorylates two serine or threonine residues in the S/T-X5-S/T (X is any amino acid) motif of its activation loop, activating a downstream MAPKK.
