The living system works in _ condition.
Correct answer: B. Isothermal
- A. Isochoric
- B. Isothermal
- C. Adiabatic
- D. Isobaric
Explanation
The living system works in isothermal conditions i.e the temperature of the body remains constant due to thermoregulatory mechanisms. This is important for enzyme activity as enzymes can work best at only a specific temperature, the optimum temperature. For humans, the optimum temperature for enzymes is 37°C.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
