Question 2. What is meant by active transport and passive transport across the cell membrane. Give one example for each.
Answer:

Active transport:

• Movement of substances against the chemical or electrical or electrochemical gradient is called active transport.
• It requires energy which is obtained by breakdown of ATP.
• Active transport It includes:
  • Primary active transport process
    • Transport of sodium and potassium
    • Transport of calcium ions
    • Transport of hydrogen ions
  • Secondary active transport process
    • Co transport
    • Counter transport
  • Carrier type processes – carrier are transport proteins
  • Vesicular transport processes – this involves endocytosis and exocytosis.

Passive transport:

• The movement of substances across the cell in this process occurs without the expenditure of energy.
• Example
  • Simple diffusion of lipid soluble substances
  • Diffusion through protein channels.
