Question

question 17 (2.5 points) what is the purpose of bile in the digestive process? a) encourages peristalsis b) emulsifies fats c) converts starches into glucose d) stores vitamins question 18 (2.5 points) external respiration involves the use of oxygen to release energy stored in nutrient molecules such as glucose true false

Explanation:

Bile is produced by the liver and released into the small - intestine. Its main function is to break down large fat globules into smaller droplets, a process called emulsification, which increases the surface area for fat - digesting enzymes to act. Peristalsis is the muscular movement of the digestive tract and is not related to bile. Starch conversion to glucose is done by enzymes like amylase. Bile is not involved in vitamin storage. For external respiration, it is the exchange of gases (oxygen and carbon - dioxide) between the body and the environment, not the use of oxygen to release energy from nutrients. The use of oxygen to release energy from nutrients like glucose is cellular respiration.

Answer:

Question 17: B. Emulsifies fats
Question 18: False
