What is the function of the epiglottis?

• stops food from entering your trachea

• adds salivary amylase to break down proteins

• adds bile to the small intestine

• stops food from entering your nasal cavity

Circle the location pepsin is secreted from

What structure allows the chyme to pass through?

• esophageal sphincter

• pyloric sphincter

• glottis

• epiglottis

What activates pepsin and what does pepsin do?

• HCl activates it in the small intestine. It breaks down complex carbohydrates into disaccharides

• HCl activates it in the stomach. It breaks down complex carbohydrates into glucose

• HCl activates it in the small intestine. It breaks down proteins into amino acids.

• HCl activates it in the stomach. It breaks down proteins into polypeptides.

Indicate the locations where physical digestion occurs?

What is the function of the microvolli of the small intestine?

• aid in complete digestion of proteins

• increase physical digestion of all macromolecules

• speed up chemical reactions

• increase absorption of monomers
