Enzymes that require an optimum temperature lower than 37°C for their proper function are present in:
Correct answer: B. Testes
- A. Mouth
- B. Testes
- C. Large intestine
- D. Stomach
Explanation
Enzymes in the testes require a temperature lower than 37 °C for proper function. The testes are located in the scrotum, outside the body, where the temperature is slightly cooler than the core body temperature. This cooler environment is essential for spermatogenesis, as sperm production and enzyme activity are temperature-sensitive. The lower temperature helps maintain the quality and viability of sperm cells.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
