Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Larger molecules and clumps of material can also be actively transported across the cell membrane by processes known as ____

A	endocytosis
B	endocytosis and exocytosis
C	exocytosis
D	protein pump action

Explanation:

Detailed explanation-1: -Cells use exocytosis to secrete molecules too large to pass through the cell membrane by any other mechanism.

Detailed explanation-2: -Large molecules, microorganisms and waste products are some of the substances moved through the cell membrane via exocytosis and endocytosis.

Detailed explanation-3: -Active transport is a kind of cellular transport in which substances like amino acids, glucose and ions are transported across cell membranes to a region that already has a high concentration of such substances.

Detailed explanation-4: -Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with th e cell membr ane. The membrane folds over the substance and it becomes completely enclosed by the membrane. At this point a membrane-bound sac, or vesicle, pinches off and moves the substance into the cytosol.
