To calculate protein we can use protein calculator online and fill our details like age, gender, height, weight, our activity level with the help of this we can find our daily protein intake diet.

Functions of enzymes are

Digestive system - enzyme helps the body break larger complex molecules into smaller molecules, such as glucose so that the body can use them as fuel.

DNA replication - Each cell in your body contains DNA. Each time a cell divides, that DNA needs to be copied. Enzymes help in this process by unwinding the DNA coils and copying the information.

Liver enzymes - the liver breaks down toxins in the body. To do this, it uses a range of enzymes.
