Question

The significance of temperature to living organisms is appreciable because it affects

• A. Kinetics of the enzymes
• B. Basal metabolism and activity
• C. Physiological functions of the organism
• D. All of the above

Answer 1

The correct option is D All of the above

Significance of temperature in living world

• Enzyme kinetics
• Basal metabolism and activity
• Physiological processes etc.

Role of temperature: Enzyme kinetics

• Temperature plays an important role in the working of the enzymes.
• This is because the functionality of enzymes is determined by its structure.
• Fluctuation from the optimal temperature range causes disruption in the structural foldings of the enzyme.
• This in turn affects its functions.

Role of temperature: Basal metabolism and activity

• Basal metabolism and activity of our body is determined by the functioning of the enzymes indirectly.
• Since, activity and turnover of enzymes is regulated by the temperature, hence, temperature has a key role determining the metabolic reactions happening in our body.

Role of temperature: Physiology

• Physiological processes are regulated by the complex interplay of enzymes.
• Temperature has a vital role in the functionalities of enzymes.
• Hence, physiology is greatly influenced by the temperature.

Final answer:
(d) All of the above
