Which of the followings statement is correct?
Correct answer: A. All enzymes in human body work at same temperature but different pH
- A. All enzymes in human body work at same temperature but different pH
- B. All enzymes in human body work at different temperature but same pH
- C. All enzymes in human body work at same temperature and same pH
- D. All enzymes in human body work at different temperature and different pH
Explanation
All enzymes in human body work at optimum temperature of 37°C with exception of testes. The pH for all enzymes is different such as pepsin works best at pH 2 while salivary amylase works best at pH 6.80.

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.
