15 Questions
Which of the following is NOT a function of the digestive system?
C) Synthesis of hormones
What role do bile salts play in digestion?
C) Emulsifying fats into smaller droplets
Which of the following is an example of chemical digestion?
D) Enzymes breaking down proteins into amino acids
List two similarities between mechanical and chemical digestion.
Similarities:
Both processes are essential for breaking down food into absorbable forms. Both occur in the digestive system and involve physical or chemical changes to food.
List two differences between chemical and mechanical digestion
Mechanical digestion involves the physical breakdown of food into smaller pieces, while chemical digestion involves breaking down complex molecules into simpler molecules using enzymes. Mechanical digestion occurs primarily in the mouth and stomach, whereas chemical digestion occurs throughout the digestive system, especially in the stomach and small intestine.
People who have had their gall bladder removed are unable to control the release of bile into the small intestine. Predict a consequence of this.
A consequence of this could be difficulty in digesting and absorbing fats, leading to digestive discomfort and possible nutrient deficiencies. This is because bile, which emulsifies fats, is no longer stored and released in a controlled manner, leading to less efficient fat digestion.
The process in which carbohydrate, protein, and fat molecules are broken down into products small enough to be absorbed into the blood and into the cells is called ________.
digestion
Mechanical digestion increases the ________ of food to allow more effective chemical digestion.
surface area
During chemical digestion, carbohydrates are split into ________, proteins are split into ________, and lipids are split into ________.
Answer: monosaccharides, amino acids, fatty acids and glycerol
Enzymes are biological catalysts that increase the rate of a reaction without being ________.
consumed
The ________ releases bile into the small intestine to aid in the emulsification of fats.
gall bladder
define mechanical digestion
The physical breakdown of food into smaller pieces to increase surface area for chemical digestion.
define chemical digestion
The process by which enzymes break down large, complex molecules into smaller, simpler molecules that can be absorbed by the body.
define bile
A digestive fluid produced by the liver and stored in the gall bladder that helps to emulsify fats in the small intestine.
define Enzymes
Biological catalysts that speed up chemical reactions in the body without being consumed in the process.
