A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules.
NettetBy inhibiting the enzyme involved in the production of dihydrofolic acid, sulfonamides block bacterial biosynthesis of folic acid and, subsequently, pyrimidines and purines required for nucleic acid synthesis. This mechanism of action provides bacteriostatic inhibition of growth against a wide spectrum of gram-positive and gram-negative pathogens. Nettet15. mar. 2024 · Since the wall is a semi-permeable membrane, it allows certain substances to pass through, such as proteins. This allows the wall to regulate diffusion in the cell and control what enters or leaves. Additionally, the semi-permeable membrane helps communication among cells by allowing signaling molecules to pass through the …
