A patient has a blocked bile duct. Which nutrient's digestion will be most affected?

Accepted Answer

Fats

Question 5

Which equation best represents the enzymatic breakdown of triglycerides by pancreatic lipase?

Accepted Answer

$	ext{Triglyceride} + 	ext{Lipase} ightarrow 	ext{Monoglyceride} + 2 	ext{Fatty acids}$

Question 6

Which accessory organ is incorrectly matched with its digestive secretion?

Accepted Answer

Gall bladder – amylase

Question 7

During digestion, which process is described by the equation $	ext{Starch} + 	ext{Amylase} ightarrow 	ext{Maltose}$?

Accepted Answer

Carbohydrate digestion in the small intestine

Question 8

A person has a genetic disorder that prevents the pancreas from releasing proteases. Which macronutrient will be least digested?

Accepted Answer

Proteins

Question 9

Which of the following best explains why bile is necessary for efficient fat digestion?

Accepted Answer

Question 10

If the pancreas fails to secrete amylase, which process will be directly impaired?

Accepted Answer

Question 13

A patient is unable to digest fats efficiently. Which accessory organ is most likely malfunctioning?

Accepted Answer

Gall bladder

Question 14

Which of the following best describes the role of the liver in digestion?

Accepted Answer

Produces bile to aid in fat digestion

Question 15

Which chemical reaction occurs during protein digestion in the small intestine?

Accepted Answer

$	ext{Protein} + 	ext{Protease} ightarrow 	ext{Amino acids}$

Question 16

Accepted Answer

The liver produces bile, which is stored in the gall bladder

Question 17

Which organ is a major source of digestive enzymes in the small intestine?

Accepted Answer

Pancreas

Question 18

Which process is described by the following: 'Bile allows fats to spread out in the liquid of the chyme so that lipase can act upon it.'?

Accepted Answer

Emulsification

Question 19

Which of the following is a correct sequence for the digestion of fats in the small intestine?

Accepted Answer

Bile emulsifies fats $\rightarrow$ Pancreatic lipase digests fats

Question 20
