Answer:
The Correct Answer is A) Enzymes.
Explanation:
Enzymes are biological molecules, usually proteins, that significantly accelerate the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.
Examples of enzymes are:
- Lipases – a group of enzymes that help digest fats in the gut.
- Amylase – helps change starches into sugars.
- Maltase – also found in saliva; breaks the sugar maltose into glucose.
- Trypsin – found in the small intestine, breaks proteins down into amino acids
