Acids and bases are important in living things because most enzymes can do their job only at a certain level of acidity. Cells secrete acids and bases to maintain the proper pH for enzymes to work. For example, every time you digest food, acids and bases are at work in your digestive system.
The answer is A) emulsified by bile salts
<span>In order for the fat to be digested, the fat globules must be emulsified first by bile salts in the stomach.
