If a cell is non-selectively engulfing samples of extracellular fluid, for example to absorb nutrients, it will likely utilize ________.

Question

Quizplus · Accepted Answer

Non-selective engulfing of extracellular fluid is referred to as pinocytosis. This process involves the ingestion of small vesicles, which are formed from the plasma membrane. Pinocytosis does not require specific receptors and is an indiscriminate process. Phagocytosis, on the other hand, involves the ingestion of larger particles and typically requires specific receptors. Exocytosis is the process by which cells secrete substances out of the cell. Receptor-mediated endocytosis involves the specific uptake of molecules that bind to receptors on the cell surface.
