Question

Cell requires constant reflux of ____.

  1. Fuel 
  2. Oil 
  3. Food 
  4. Energy 

hintHint:

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.
