Question
Cell requires constant reflux of ____.
- Fuel
- Oil
- Food
- Energy
Hint:
The requirement of ATP by a cell.
The correct answer is: Energy
- A cell undergoes several catabolic and anabolic reactions for its survival
- Anabolic reactions generate a complex compound from simple units
- Catabolic reactions break down a complex compound into simpler units
- Both anabolic and catabolic reactions require energy to perform the reactions
- For example, consider a catabolic reaction like glycolysis. Here, ATP is used to break down glucose into pyruvate.
- Similarly, consider an anabolic reaction like glycogenesis where glycogen is produced from glucose using ATP.
