what are the types of passive transport?
what movement of particles is diffusion?
movement from an area of high concentration to an area of low concentration
movement from an area of low concentration to an area of high concentration
Passive transport means energy is required
Whats the difference between diffusion and facilitated diffusion?
theres no difference
facilitated diffusion uses carrier proteins
facilitated diffusion requires energy
diffusion is through a semi-permeable membrane and facilitated diffusion is through a permeable membrane
Active transport is the movement of particles from an area of low concentration to an area of high concentration
what factors affect diffusion
concentration gradient, (difference between the two regions)
what is osmosis?
a passive movement of water through a semi-permeable membrane
a process of diffusion where energy is required to move water through a semi-permeable membrane
passive transport is when the particles are moved down the concentration gradient
