In the fluid mosaic model: plasma membrane proteins orient their hydrophilic sides toward the internal bilayer. phospholipids often flip-flop between the inner and outer layers. the mosaic refers to proteins attached to the underlying cytoskeleton. the fluid refers to the phospholipid bilayer. the mosaic refers to the symmetry of the internal membrane proteins and sterols.
Put the following structures in order according to the pathway of a secreted protein: a. plasma membrane b. Golgi bodies c. endoplasmic reticulum d. post-Golgi vesicles
Which of the following methods of transport is being used to transfer the substance into the cell in the accompanying graph? a. diffusion down a concentration gradient b. osmosis c. facilitated diffusion d. active transport e. vesicular transport f. It is impossible to tell with the information provided.
Distinguish between the following pairs of terms: a. diffusion; osmosis b. passive transport; active transport c. endocytosis; exocytosis
Describe the general functions of the following in a eukaryotic cell: the plasma membrane, cytoplasm, DNA, ribosomes, organelles, and cytoskeleton.
What controls the passage of molecules into and out of the nucleus? a. endoplasmic reticulum, an extension of the nucleus b. nuclear pores, which consists of membrane proteins c. nucleoli, in which ribosome subunits are made d. dynamically assembled microtubules e. tight junctions
Visit this link (http://openstaxcollege.org/l/diffusion) to see diffusion and how it is propelled by the kinetic energy of molecules in solution. How does temperature affect diffusion rate, and why?
What kind of transport mechanism in cells involves ligands binding to specific receptor proteins on the surface of the plasma membrane that triggers vesicle formation? A facilitated diffusion B pinocytosis receptor-mediated endocytosis simple diffusion
Which of the following is FALSE regarding membrane transport? O A cell can add proteins into its membrane through the process of exocytosis O lons like Na+ or K+ do not enter a cell via simple diffusion O Hydrophobic molecules usually enter a cell via protein channels O lon channels must be integral proteins
In which situation would passive transport not use a transport protein for entry into a cell? water flowing into a heypertonic environment an ion flowing into a nerve cell to create an electrical potential glucose being absorbed from the blood oxygen moving into a cell after oxygen deprivation
In facilitated diffusion and active transport, how do transport proteins affect the rate of movement of molecules across the phospholipid selectively permeable membrane? A Transport proteins decrease the rate of movement of molecules. B Transport proteins stop the rate of movement of molecules. © Transport proteins increase the rate of movement of molecules. Transport proteins ensures all molecules may pass the membrane simultaneously.
Some nutrients and other types of particles can be taken into a cell when the cell's plasma membrane encloses the particles and pinches off, forming a free-floating vesicle inside the cell. A lysosome containing digestive enzymes then fuses with the vesicle. Which term best classifies the uptake of such particles by the cell? Simple diffusion OEndocytosis O Exocytosis Facilitated diffusion
