Below are the questions for the exam with the choices of answers:
Question #1
A the diffusion of a substance across a biological membrane without the expenditure of energy
B This model states that the membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids
C binding of specific solutes to receptors triggers vesicle formation
Question #2
A saturated fatty acids, unsaturated fatty acid and cholesterol
B also called cell drinking, molecules dissolved in droplets are taken up when extracellular fluid is “gulped” into tiny vesicles
C binding of specific solutes to receptors triggers vesicle formation
Question #3
A also called cell drinking, molecules dissolved in droplets are taken up when extracellular fluid is “gulped” into tiny vesicles
B Proteins are bound to the surface of the membrane
C transport vesicles migrate to the membrane, fuse with it, and release their contents outside the cell
Question #4
A Membranes have distinct inside and outside faces
B A coupled active transport by a membrane protein. It occurs when active transport of a solute indirectly drives transport of other substances
C transport vesicles migrate to the membrane, fuse with it, and release their contents outside the cell
Question #5
A A coupled active transport by a membrane protein. It occurs when active transport of a solute indirectly drives transport of other substance
B a transport protein that generates voltage across a membrane
C This is the tendency for molecules to spread out evenly into the available spaces
Question #6
A a transport protein that generates voltage across a membrane
B The voltage across a membrane
C the diffusion of a substance across a biological membrane without the expenditure of energy
Question #7
A The voltage across a membrane
B This is the ability of a surounding solution to cause a cell to gain or lose water
C This transport requires energy, usually in the form of ATP hydrolysis, to move substance against their concentration gradients
Question #8
A the control of solute concentartion and water balance, is a necessary adaptation for life in such environments
B This transport requires energy, usually in the form of ATP hydrolysis, to move substance against their concentration gradients
C These ion channels open or close in response to a stimulus
Question #9
A These ion channels open or close in response to a stimulus
B the membrane pulss away form cell wall, causing the plant to wilt
C This is type of passive transport aided by channel proteins and carrier proteins
Question #10
A The voltage across a membrane
B the membrane pulls away from cell wall, causing the plant to wilt
C This is type of passive transport aided by chanel proteins and carrier proteins
Question #11
A the control of solute concentrations and water balance, is a necessary adaptation for life in such environments
B These ion channels open or close in response to a stimulus
C the membrane pulss away form cell wall, causing the plant to wilt
Question #12
A This is the ability of a surrounding solution to cause a cell to gain or lose water
B This transport requires energy, usually in the form of ATP hydrolysis, to move substance against their concentration gradients
C the control of solute concentartion and water balance, is a necessary adaptation for life in such environments
Question #13
A the diffusion of a substance across a biological membrane without the expenditure of energy
B The voltage across a membrane
C This is the ability of a surounding solution to cause a cell to gain or lose water
Question #14
