(d) Bile
(e) Salivary amylase
(f) HCL
Answers
Answer:
bile juice is secreted by liver. it doesn't contain any enzymes. it contains bile salts.it turns the acidic medium to alkaline medium for complete digestion in small intestine. it breaks down large fat molecules into small fat molecules. this process is known as emulsification of fats.
salivay amylase is the enzyme present in saliva which is secreted by salivary glands.it breaks down starch to give sugar.or maltose.
hydrochloric acid creates an acidic medium which which facilitates the action of the enzyme pepsin (protein digesting enzyme).it kills the bacteria present in food.
Bile is a fluid that is yellowish-green in color, which is released from the liver and held in the gallbladder until it is needed. It is mostly composed of bile acids, also referred to as bile salts, and bilirubin, which is a byproduct from the breaking down of red blood cells and cholesterol. Water, sodium, potassium and metals are also found in bile, but in much smaller amounts. Now you are probably wondering, what is the purpose of this fluid and how does it help you enjoy some things that you like?
