Viruses are complicated assembles of molecules, including proteins, nucleic, acids, lipids, and carbohydrates, but viruses on there own cant do nothing until the enter a living cell to infect. without cell viruses would not be a able to multiply thats why viruses are not liveing things

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.
