View Biology Active And Passive Transport Worksheet Background. Active and passive transport are systems that are meant for transporting molecules through the cell membrane. A type of passive transport which uses special proteins to aid the movement of materials is called facilitated diffusion.
Movement of materials in and out of the cell. Let's begin our journey into passive and active transport of substances across cell membranes. Active and passive transport are biological processes that move oxygen, water and nutrients into cells and remove waste products.
The particles move against the concentration gradient, using energy released during respiration.
Active transport in the largest biology dictionary online. Usually, molecules are traveling against a concentration gradient. Active transport requires cellular energy to achieve this movement. Active and passive transport are systems that are meant for transporting molecules through the cell membrane.
