Voltage-gated sodium channels represent the chemical (or molecular<span>) level of structural organization in muscle sarcolemma.
Chemical level of structural organization is the first and the simplest level within the structural hierarchy. It includes the smallest unit of any of elements-atom, which combine to form molecules and macromolecules which also combine to form organelles, the functioning units of a cell. Sodium channels are membrane proteins which means that they are macromolecules.</span>

Answer: One consequence of neutralizing the pH in the intestine is that ENZYMES THAT CATALYZE THE HYDROLYSIS OF CARBOHYDRATES ARE ACTIVE.
Explanation: During digestion, partially digested food particles are transported from the stomach to the first part of the small intestines, that is, the duodenum. The food particles that are coming from the stomach are acidic due to the secretion of hydrochloric acid in the stomach. This acidity has to be removed when the food particles get into the duodenum, this is because the enzymes that are needed to break down carbohydrates in the duodenum can not work in acidic medium. Thus, in order for the pancreatic amlayse enzyme to become active and to complete the break down of carbohydrate in the duodenum, the secretin hormone has to stimulate the release of bicarbonate that will neutralize the acidic partially digested food particles from the stomach.
