PATHOPHYSIOLOGY 8TH EDITION MCCANCE TEST BANK Chapter 1: Cellular Biology MULTIPLE CHOICE 1. Which statement best describes the cellular function of metabolic absorption? a. Cells can produce proteins. c. Cells can take in and use nutrients. b. Cells can secrete digestive enzymes. d. Cells can synthesize fats. ANS: C In metabolic absorption, all cells take in and use nutrients and other substances from their surroundings. The remaining options are not inclusive in their descriptions of cellular ...

Essential Membrane Functions correct answer: act as barrier regulate import and export of molecules compartmentalization of processes increases efficiency membrane properties correct answer: composed of lipid bilayer impermeable to polar molecules asymmetric membrane fluidity correct answer: lipids and proteins rotate or move within bilayer; allows cell movement, growth, division, secretion, cell junction formation, and self-heal if punctured comformational changes mediate fluid...

functions of the membrane correct answer: -the structure of the membrane is key for its function -act as a barrier regulating import and export of molecules -help with compartmentalization of the cell, creating particular environments for certain processes so multiple specialized processes could occur at once -modulates cell-cell recognition with their glycoproteins and glycolipids located on the outer leaflet facing the cytosol -signaling across the membrane by proteins and lipids p...

How does membrane formation occur? correct answer: decrease in ionic bond with water What are the main functions of the cell membrane? correct answer: - barrier regulating the import and export of essential molecules - Compartmentalization of specialized processes increases cellular efficiency. - modulates cell-cell recognition due to the presence of glycoproteins and glycolipids. - Signalling across the membrane is mediated by proteins and lipids. What is the fluid mosaic model? corr...

Bio 1201 exam 2 Gregg latest update graded A+ transport proteins are responsible for controlling passage across the membrane fluid mosaic model The membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids fatty acid tails nonpolar, hydrophobic fatty acid heads hydrophilic, polar periphial proteins bound to the surface of the membrane integral proteins penetrate the hydrophobic core (ones that span the membrane are transmembrane protiens How ...

BIOL1P91 Final Exam Prep test Questions With Verified Answers What are the 4 functions of the cell membrane 1. seperating internal and external environment 2. regulating traffic in the cell 3. Holding contents of the cell in place 4. creates interface for cellular activity What is the structure of the cell membrane - phospholipid bilayer - integral and peripheral membrane proteins - carbohydrate bonded to proteins - fluid mosaic model - asymmetrical leaflets fluid mosaic model of...

PATHOPHYSIOLOGY 8TH EDITION MCCANCE TEST BANK NURSINGTB.COM The lysosomal membrane acts as a protective shield between the powerful digestive enzymes within the lysosome and the cytoplasm, preventing their leakage into the cytoplasmic matrix. Disruption of the membrane by various treatments or cellular injury leads to a release of the lysosomal enzymes, which can then react with their specific substrates, causing cellular self-digestion. The other options do not correctly describe this pr...

why do specimens need to be thin when observing them under a light microscope? - to allow light to pass through identify and explain the starch test - add iodine dissolved in potassium iodide solution to the sample - positive test = blue-black - negative test = orange-brown why is the structure of the plasma membrane often referred to as the fluid mosaic model? - - the continuous bilayer is 'fluid' as the phospholipid molecules are constantly moving - protein molecules are scattered thr...

BIOL 133 Exam 1- Chapters 1-6 Part 1 of 1 - 1. Molecules move from a high to low concentration in 2. What is the pathway in which a protein moves through the endomembrane system? 3. The cell theory states 4. If two solutions are different, the one will the higher concentration of solutes is 5. What biological macromolecule provides the initial instructions for the primary sequence of proteins? 6. When the solute concentration in solution 1 is lower than the solute concentration in sol...
