Active and Passive Transport

passive transport  Active transport necessitates energy to move substances against their concentration gradient, whereas passive transport requires no cellular In Active transport the molecules are moved across the cell membrane, pumping the molecules against the concentration gradient using ATP In Passive

There are four different types of Passive membrane transport, these are: Diffusion, Osmosis, Facilitated diffusion and Filtration Diffusion is 5 Active transport requires carrier proteins In passive transport carrier proteins are not involved However, in facilitated diffusion

Passive Transport Some materials, like water and oxygen, can enter and leave cells without the cell needing to expend any energy This is passive transport Brute-force simulations of protein transport reveal telegraph-like behavior, where prolonged diffusion on one side of the
