Identify the correct mode of transport from the following de

Identify the correct mode of transport from the following descriptions. facilitated diffusion (passive transport) The method by which a non- polar molecules such oxygen enters cells: The transport of glucose from the lumen of small intestines into epithelial cells alongside the transport of Na+. In this case glucose moves against a concentration gradient (from low concentration to high concentration) and sodium moves down its concentration gradient, i.e., from the compartment with high concentration to one with low concentration. simple diffusion active transport secondary active transport (indirect active transport) exocytosis The uptake of cholesterol in the form of low density lipoproteins (LDL) through binding to receptors on the cell surface. receptor mediated leukocytosis. phagocytosis Transport of a polar molecule such as glucose from the bloodstream into cells by protein transporters. The process does not require input of energy and proceeds from compartment with high concentration (bloodstream) to one with low concentration (intracellular compartment). The release of hormones such as insulin by cells into the bloodstream. The transport of protons (H+) from the cytoplasm of cells lining the stomach, which has neutral pH (pH 7), to the stomach lumen which has a low pH (pH The process uses ATP as an energy source. This is the process through which white blood cells or amoeba engulf of bacteria and other large particles.
