Yes, that is true. What is your question?
Statement D. Is not true.
1)Enzyme is a protein. The main material of an enzyme is protein
2)It is easily influenced, by environmental change. Environmental factors include temperature, pH, and inhibitor.
3)It acts as catalyst The enzyme functions in accelerating chemical reaction, but the enzyme itself does not change after the reaction ends.
If we dont have enzymes then we would become malnourished as our body wouldnt be able to absorb the nutrients. Enzymes work in digestion to break down the food we eat
