Practice AP Biology Structure and Function of Plasma Membranes in the app →The accepted model of plasma membrane structure proposed by Singer and Nicolson is called the:The main fabric of the plasma membrane is built from:A phospholipid molecule is built on a backbone of:Plasma membranes are described as selectively permeable, which means they:When a cell sits in a hypotonic solution, water:When a cell sits in a hypertonic solution, water:The three terms used to compare a cell's osmolarity with its surroundings are hypotonic, hypertonic and:The first widely accepted model of membrane structure, from 1935, was proposed by:Compared with a plasma membrane, a human red blood cell is roughly:Myelin, which insulates peripheral nerve axons, is unusual because it contains only:The mitochondrial inner membrane is protein-rich, at:The transmembrane segment of a single-pass integral membrane protein is typically:Carbohydrates on the outer membrane surface matter to the immune system because they:The state in which a substance has spread out so there is no net movement is called:All else being equal, heavier molecules diffuse:Raising the temperature of a system makes diffusion:A large spherical cell is at risk because:Channel proteins move molecules at what rate relative to carrier proteins?Glucose appears in the urine when blood glucose is very high because:A double bond between adjacent carbons in a fatty acid tail creates a bend of about:Red blood cells are preferred for osmolarity studies because they:A cloudy suspension of cells can have a lower osmolarity than a clear solution because osmolarity counts:A very fine needle can pierce a plasma membrane without bursting the cell because the membrane:HIV is hard to vaccinate against partly because its surface recognition sites:
