PATHOPHYSIOLOGY 8TH EDITION MCCANCE TEST BANK QUESTIONS AND ANSWERS

How do cells become specialized - correct ans--through the process of differentiation or maturation what are the eight specialized cellular functions - correct ans--movement, conductivity, metabolic absorption, secretion, excretion, respiration, reproduction, communication The eukaryotic cell consist of three components - correct ans--the plasma membrane the cytoplasm and the intracellular organselles where is the nucleus found - correct ans--center of the cell what is the largest bound membrane bound orgenell - correct ans--the nucleus what are the chief functions of the nucleus - correct ans--cell division and control of genetic information What is cytoplasm? - correct ans--the material or protoplasm within a living cell, excluding the nucleus. what are organelles are suspended ? - correct ans--in cytoplasm and biologic membrane Golgi apparatuses - correct ans--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? - correct ans--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 - correct ans--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? - correct ans--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 - correct ans--site of cellular protein synthesis what is the golgi complex - correct ans--a network of smooth membranes and vesicles located near the nucleus Lysosomes function - correct ans--sacs that contain digestive enzymes that help break down macromolecules amino acids carbohydrates fatty acids what is the function of the golgi complex - correct ans--responsible for processing packaging proteins into secretory vesicles that break away from the golgi complex and migrate to a variety of intracellular and extracellular destinations. including plasma membrane Autophagy - correct ans--A process in which lysosomes decompose damaged organelles to reuse their organic monomers what does autography play a crucial role in - correct ans--health and disease what is peroxisomes - correct ans--are similar to lysomes but contain several oxidative enzymes such as catalase and urate oxidase what are the function if mitochondria - correct ans--cellular respiration and energy production What are vaults and what do they do? - correct ans--cytoplasmic organelles also called ribonucleoprotiens they are thought to function as cellular trunks carrying mRNA from nucleas to the ribosomal sites of protein synthesis - correct ans--
