Question

Which cell activity does not require the supply of ATP?
1. Passive transport
2. Cell division
3. Active transport
4. Protein synthesis

Answer 1

Correct Answer - Option 1 : Passive transport

The correct answer is Passive transport.

• Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level.
• Passive transport does not require the supply of ATP.
• Simple diffusion also does not require energy.
• ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups.
• In addition to providing energy, the breakdown of ATP through hydrolysis serves a broad range of cell functions, including signaling and DNA/RNA synthesis.
• ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.

• Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells.
• Mitochondria are known as the 'Powerhouse of the cell'.
• During glycolysis, 2 ATP is derived in the process.
• Glycolysis is an anaerobic process.
