Question

Low temperature reduces the

A. activity of microorganisms by reducing the chemical reaction and action of enzymes.
B. cheapest form of radiation for food preservation.
C. concentrations of an antibiotic, thus resistant strains finally develop.
D. hazard is reported and possible control measures are identified.​

Answer 1

Low temperature reduces the

A. activity of microorganisms by reducing the chemical reaction and action of enzymes.

B. cheapest form of radiation for food preservation.

C. concentrations of an antibiotic, thus resistant strains finally develop.

D. hazard is reported and possible control measures are identified.

Answer 2

Explanation:

Decrease in temperature cause an exponential reduction of the reaction rate, and the magnitude of which depends on the value of the activation energy. Consequently, most biological systems display a reaction rate 23 times lower when the temperature is decreased by 10°C (Q10 value).
