Formation of heat shock proteins in plants results in___________?
Correct answer: B. Embracing the enzymes and other proteins and prevent their denaturation.
- A. Elevation of temperature in cold conditions.
- B. Embracing the enzymes and other proteins and prevent their denaturation.
- C. Change the chemical nature of other proteins thus making them heat resistant.
- D. Help in evaporative cooling.
Explanation
Heat shock proteins act as molecular chaperones during heat stress by binding to vulnerable proteins, helping them retain their functional shape and preventing denaturation or aggregation. They do not raise the temperature in cold conditions. Students may choose option c because heat shock proteins are associated with heat tolerance, but they protect proteins rather than chemically changing them into heat-resistant proteins.

About Thermoregulation
Thermoregulation maintains body temperature through negative feedback controlled mainly by the hypothalamus. It covers vasodilation and vasoconstriction, sweating, shivering, changes in metabolic heat production and behavioural responses, while distinguishing heat loss by radiation, conduction, convection and evaporation from temperature regulation itself.
