Diffusion occurs from areas of high concentration to low concentration of a specific molecule, ion, or atom. For example, if equal amounts of sodium and potassium ions are separated by a semipermeable barrier, the potassium ions will flow through the barrier to the area of low potassium concent...
Diffusion is the movement of a molecule down a concentration gradient, from an area of its high concentration to an area of its low concentration. This process is passive, i.e. it requires no input of additional energy; the concentration gradient alone is enough to drive the process. Types ...
Simple diffusion is the movement of molecules across a cell membrane from an area of high concentration to an area of low concentration. This process does not require the assistance of any membrane proteins. However, the rate of simple diffusion can be affected by the composition of the cell ...
Switch to new thesaurus Noun 1. diffusion - (physics) the process in which there is movement of a substance from an area of high concentration of that substance to an area of lower concentration natural philosophy, physics - the science of matter and energy and their interactions; "his favo...
Step-by-Step Solution:1. Understanding Simple Diffusion: - Simple diffusion is the movement of particles from an area of high concentration to an area of low concentration, which is also known as downhill tr
2. Movement Along Concentration Gradient: In both processes, substances move along the concentration gradient, meaning they move from areas of high concentration to areas of low concentration. This is often referred to as "downhill transport." 3. Characteristics of Simple Diffusion: - Simple diff...
The 2 methods were compared with respect to their sensitivity, reaction range, reaction time, resolving power and susceptibility to concentration and temperature artifacts. The following observations were made: 1. The potential sensitivity of the double diffusion method is somewhat greater than that of...
What is the difference between simple and facilitated diffusion? A) Facilitated diffusion requires energy whereas simple diffusion does not. B) Simple diffusion moves a solute from an area of high concentration to low concentration whereas facilitated di What is facilitated diffusion and why is it im...
The effect of diffusion boundary layers in an in vitro membrane permeation system on the membrane diffusivity of drugs was investigated based on the three-layer model. A simple method for evaluating the intrinsic diffusivity through the membrane was developed and the intrinsic diffusivity of progesteron...
Simple diffusion of molecules occurs: a) from an area of lesser concentration to an area of greater concentration. b) until those molecules are more highly concentrated on one side of the plasma membrane. c) only in molecules that are in a gaseous stat...
