1. What is a selectively permeable membrane? 2. What is a semi-permeable membrane? Membranes: The cytoplasmic surface of all living cells is bounded by a living membrane known as the plasma membrane or plasmalemma. It is an elastic, porous, selectively permeable living mem...
How does the concentration of a solute on the two sides of a membrane affect passive transport? 1. What is a selectively permeable membrane? 2. What is a semi-permeable membrane? Explain the T cell-mediated immune response. Also, these cells specialize in n...
A semipermeable membrane is a continuous sheet or film of a suitable material (natural or synthetic) which contains very small pores.
What is a Semipermeable Membrane? Discussion Comments By scifreak — On Apr 20, 2011 Since cells are selectively permeable, does that mean they can be selective and allow prescribed medications into the blood stream? For example, I take high blood pressure medicine. Is the reason it works is...
Step-by-Step Text Solution:1. Definition of Osmosis: Osmosis is defined as the movement of solvent (usually water) from an area of lower solute concentration to an area of higher solute concentration through a
The membrane does not merely keep harmful substances from reaching the interior. It is selectively permeable, allowing vital substances in but barring others, like the bouncer at a trendy nightclub. It also selectively allows the ejection of waste products. Some proteins embedded in the membrane act...
Is turgor a pressure? Turgor pressure isthe hydrostatic pressure in excess of ambient atmospheric pressurewhich can build up in living, walled cells. Turgor is generated through osmotically driven inflow of water into cells across a selectively permeable membrane; this membrane is typically the plasma...
ait occurs whenever water molecules diffuse from a region of higher concentration through a selectively permeable membrane,such as a cell membrane. 它发生,每当水分子从更高的浓度的区域散开通过一个有选择性地有渗透性的膜,例如细胞膜。[translate] ...
Two solutions of differing glucose concentrations are placed in a container separated by a selectively permeable membrane that restricts large molecules like glucose but allows the free diffusion of water. What will be the glucose concentration in the con ...
it is the diffusion of solutes across a selectively permeable membrane. a selectively permeable membrane is one that allows only specific ions and molecules to pass through, while it obstructs the movement of others. osmosis: it is the movement of solvent molecules from the region of lower ...
