pathophysiology Questions And Answers

How do cells become specialized - through the process of differentiation or maturation what are the eight specialized cellular functions - movement, conductivity, metabolic absorption, secretion, excretion, respiration, reproduction, communication The eukaryotic cell consist of three components - the plasma membrane the cytoplasm and the intracellular organselles where is the nucleus found - center of the cell what is the largest bound membrane bound orgenell - the nucleus what are the chief functions of the nucleus - cell division and control of genetic information What is cytoplasm? - the material or protoplasm within a living cell, excluding the nucleus. what are organelles are suspended ? - in cytoplasm and biologic membrane Golgi apparatuses - a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport. what is the endoplasmic reticulum? - a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis. function of golgi apparatuses - processes and packages protiens secretory vesicles that break away from the gogli complex and migrate to a variety of intracellular extra cellular destinations what is the function of the endoplasmic reticulum? - specializes in the sythesis and transport of protein and lipid components of most of the organelles. importantly the er is responsible for protein folding and sensing cell stress what is the endoplasmic reticulum - site of cellular protein synthesis what is the golgi complex - a network of smooth membranes and vesicles located near the nucleus Lysosomes function - sacs that contain digestive enzymes that help break down macromolecules amino acids carbohydrates fatty acids
