BSC 215 Study Guide - Quiz Guide: Fibrocartilage, Uterus, Brownian Motion
Document Summary
Active: the movement of molecules from an area of low concentration to high concentration and uses energy from atp. Exocytosis: the process by which materials are exported out of the cell. Endocytosis: the process by which materials move into the cell. Passive: the diffusion of molecules from an area of high concentration to an area of low concentration across a cell membrane that uses no cellular energy. Osmosis: the movement of a solvent from a higher water concentration to a lower water concentration until there is equilibrium. Filtration: the movement of solvents across the cell membrane due to pressure. The brownian movement: phenomenon that states all molecules are in constant random motion because of their inherent kinetic energy. Diffusion: process in which there is the greater movement of molecules from a region of high concentration to a region of lower concentration.
