Question

Total energy present in a biological system is called:

• A. kinetic energy
• B. activation energy
• C. entropy
• D. enthalpy

Answer 1

The correct option is D enthalpy

Enthalpy of a system is equal to the total heat content of a system or it is equal to the internal energy of the system plus the product of pressure and volume.

Hence the total energy in a biological system will be enthalpy.
