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>
Answer:
Positive feedback loops enhance or amplify changes; this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes; this tends to hold a system to some equilibrium state making it more stable.
Some examples of positive feedback are contractions in child birth and the ripening of fruit; negative feedback examples include the regulation of blood glucose levels and osmoregulation.
