D Correct answer
Explanation

Proteins are an important component and are the building block of each cell and perform various functions like:

  • Proteins act as the transporter, it transports the minerals and nutrients across the cell membrane, transport oxygen molecule and is responsible for the connection of the two cells.
  • All the enzymes are proteins and they catalyze various reactions and increases the speed of the reaction.
  • Receptors are the proteins that receive some chemical signals and respond according to them. They change their physiology according to the chemical reaction and signals.
  • ATP is the main source of energy, proteins and fats are the nutrients that sometimes help in the production of a small amount of energy.
So, the correct option is 'Main energy source'.
