You modify the gene for an integral membrane protein so that the cytoplasmic portions of the protein are deleted. when the gene is inserted in cells, what happens to the mobility of this protein in the membrane?

youre right there are

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.
