What is it called when part of a cell membrane closes around a molecule to allow the molecule to enter the cell?

It is called endocytosis

Endocytosis is a cellular process and a form of active transport in which food or other substances are transported into the cell through the cell membrane. In this process, the substance to be transported is enclosed by a part of the cell membrane which later buds off in the cell to produce a vesicle that contains the engulfed substance. Endocytosis includes; (i) pinocytosis; process of engulfing of liquid substances through the cell membrane and (ii) phagocytosis; process of engulfing of solid substances through the cell membrane.

post-impressionism is a predominantly french art movement that developed roughly between 1886 and 1905, from the last impressionist exhibition to the birth of fauvism. post-impressionism emerged as a reaction against impressionists' concern for the naturalistic depiction of light and color.

hope this have a good day

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
