They are inhibitors of key enzymes in the nervous system:
Correct answer: E. Pesticides DDT and parathione
- A. Calcium and Potassium
- B. Substrate and activators
- C. Hexokinase and glucose
- D. Magnesium and manganese
- E. Pesticides DDT and parathione
Explanation
The correct answer is E Pesticides DDT and parathione. Pesticides such as DDT (dichlorodiphenyltrichloroethane) and parathion are known to be inhibitors of key enzymes in the nervous system. DDT was commonly used as an insecticide, while parathion is an organophosphate insecticide. Both of these pesticides can affect the activity of enzymes in the nervous system, leading to adverse effects on the functioning of nerve 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.
