Active transport requires energy, but passive transport does not

|
Active transport results in equilibrium, but passive transport does not
|
|
|
Passive transport requires a protein channel, but active transport does not
|
|
|
Passive transport results in a concentration gradient, but active transport does not
|
Detailed explanation-1: -Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
Detailed explanation-2: -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).
Detailed explanation-3: -Answer and Explanation: The three types of passive transport are simple diffusion, osmosis, and facilitated diffusion. Simple diffusion. During simple diffusion, a substance such as oxygen moves from an area of high concentration to an area of low concentration.
Detailed explanation-4: -Active transport involves the movement of molecules from lower concentration to higher concentration with the use of energy. Passive transport involves the movement of molecules from higher concentration to lower concentration and no amount of energy is required.
Detailed explanation-5: -Active transport helps in the transport of large cells, proteins, ions, complex sugars, etc. Passive transport helps in transporting soluble molecules such as carbon dioxide, oxygen, water, lipids, sex hormones, etc.
