7.3 Cell Transport

What makes atoms and molecules wiggle; something that all molecules and matter have

the movement of particles from an area of high concentration to an area of low concentration

during diffusion what is the movement of the particles apart of the process?

con = concentration

what does it mean when a system reaches equilibrium?

• when particles are moving equally in all directions and spread out as much as possible

• the movement of particles from an area of high concentration to an area of low concentration

• when particles are moving not equally (in all directions) in all directions and condensed in as much as possible

• the energy that all matter has; that make atoms and molcules wiggle

when particles are moving equally in all directions and spread out as much as possible.

What is passive transport? What are traits of passive transport?

• only uses kinetic energy

• moves substances across the membrane until equilibrium, is reached

• uses ATP to move substance through membrane

• moves substances across the membrane until ostomies is reached

what refers to moving things around cells, their surroundings, or in and out of membranes

something is able to cross membrane

something cannot cross membrane

what are cell membrane for permeability?
