Answer:
The digestion of carbohydrates begins in the mouth and ends in the small intestine.
Explanation:
The absorption of carbohydrates, depending on whether they are simple or complex, will begin their digestion in the mouth by the action of saliva in food, where starches are initially separated; Once this food bolus reaches the stomach, the hydrochloric acid acts, to end later in the small intestine. Amylase, a component of pancreatic juice, ends the digestive process of carbohydrates by transforming starches into maltose, which are then transformed into monisacarides (glucose, galactose, fructose), which is the way they are absorbed by the body. In the liver they are again transformed into glucose.

Answer:
(B). inhibiting HMG-CoA reductase.
Explanation:
Lovastatin is a drug, which is used to reduce risk for cardiovascular diseases and to reduce level of cholesterol in blood.
It works by inhibiting HMG-CoA reductase (3-hydroxy-3-methylglutaryl-coenzyme A reductase) enzyme, required for the formation of mevalonate from HMG-CoA.
Mevalonate is building block for the biosynthesis of cholesterol. Hence, lovastatin inhibits cholesterol production by inhibiting synthesis of mevalonate.
Thus, the correct answer is option (B).
