The activity of enzyme is increased in the presence of certain substances known as co-enzymes or acticators. T or F

Answer

**Step-by-Step Solution:**

1. **Understanding Enzymes**: Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are primarily made up of proteins and are highly specific in their action.

2. **Role of Enzyme Activators**: Enzyme activators are substances that can bind to enzymes and enhance their activity. These activators can increase the efficiency of the enzyme, allowing it to catalyze reactions more effectively.

3. **Coenzymes**: Coenzymes are a specific type of enzyme activator. They are organic molecules that assist enzymes in their catalytic activity. For example, vitamins often serve as coenzymes.

4. **Conclusion**: Since enzyme activators, including coenzymes, do indeed increase the activity of enzymes, the statement in the question is true.

5. **Final Answer**: Therefore, the answer to the question is True.
