What are active transport and passive transport?
Active transport is defined as the movement of molecules across the cell membrane by using cellular energy. Passive transport is the movement of molecules across the membrane without the use of ATP. This process requires energy in the form of ATP. No cellular energy is required in this process.
What is active and passive transport Class 9?
Active transport requires energy for the movement of molecules whereas passive transport does not require energy for the movement of molecules. In active transport, the molecules move against the concentration gradient whereas in passive transport, the molecules move along the concentration gradient.
What do you mean by active and passive transport Class 9?
In Active transport the molecules are moved across the cell membrane, pumping the molecules against the concentration gradient using ATP (energy). In Passive transport, the molecules are moved within and across the cell membrane and thus transporting it through the concentration gradient, without using ATP (energy).
What are the differences between active and passive transport?
Active transport utilizes energy while on the other hand passive transport does not require any energy.
What are the different types of active and passive transport?
Osmosis. In the process of osmosis,the water,and other molecules or substance are transport through the selectively permeable cell membrane.
What are the functions of active and passive transport?
Passive transport allows molecules to pass the cell membrane through a concentration gradient
How to compare and contrast active and passive transport?
Simple Diffusion: Solutes move from a region of higher concentration to lower concentration.
