Answer 1

Answer:

Active transport requires energy from the cell. It occurs when substances move from areas of lower to higher concentration or when very large molecules are transported. Types of active transport include ion pumps, such as the sodium-potassium pump, and vesicle transport, which includes endocytosis and exocytosis.

Answer:

Sometimes molecule need the help of special transport protiens to move across the cell membrane. Some molecules even need an imput of energy to help get them across the cell membrane. The movement of molecules across a membrane without the input of energy is known as passive transport.
