a) isolation
b) production
c) deletion
d) both a and b
Which of the following enzyme affects the texture and freshness of bread dough?
a) amylase
b) protease
c) lipase
d) nuclease
Explanation:Amylase is an enzyme, or special protein, that helps you digest carbohydrates. Most of the amylase in your body is made by your pancreas and salivary glands. A small amount of amylase in your blood and urine is normal.
A protease (also called a peptidase or proteinase) is an enzyme that catalyzes (increases reaction rate or "speeds up") proteolysis, breaking down proteins into smaller polypeptides or single amino acids, and spurring the formation of new protein products.
Lipase is a type of protein made by your pancreas, an organ located near your stomach. Lipase helps your body digest fats. It's normal to have a small amount of lipase in your blood. But, a high level of lipase can mean you have pancreatitis, an inflammation of the pancreas, or another type of pancreas disease.
Nuclease, any enzyme that cleaves nucleic acids. Nucleases, which belong to the class of enzymes called hydrolases, are usually specific in action, ribonucleases acting only upon ribonucleic acids (RNA) and deoxyribonucleases acting only upon deoxyribonucleic acids (DNA).
