passive movement Flashcards
what is movement that doesn’t require energy
passive transport
what happens in the process of diffusion
is the process where molecules move passively from a high concentration area to a low concentration area
where does diffusion occur
in liquids and gases
when does diffusion occur
diffusion occurs when a cell reaches an equilibrium
what happens when you increase a concentration gradient
when the concentration gradient increases the difference in particle concentration between two regions will also increase
how do larger molecules pass through differently to small molecules
they use facilitated diffusion this is where carrier proteins and channel proteins are used
how is the diffusion of water across molecules different
diffuse differently through the use of a rapid diffusion through a permeable cell membrane from a low solute to a high solute concentration
