Bio- Lesson 1

Question 1

Digestion

Answer 1

The mechanical and chemical breakdown of food particles into smaller absorbable monomers

Question 2

Monomers

Answer 2

A food particle that is small enough to pass through the membrane of the digestive tract

Question 3

Mechanical Digestion (MD)

Answer 3

The breakdown of food through physical means such as: Mastication, Peristalsis, Churning and emulsification.
MD also mixes food with the digestive juices and enzymes

Question 4

Chemical Digestion (CD)

Answer 4

The breakdown of food through a series of catabolic reactions tat are catalyzed by enzymes and digestive juices

Question 5

Metabolism

Answer 5

The sum of all the chemical reactions of the body

Question 6

Catabolism

Answer 6

Reactions in which large molecules are broken down into smaller molocules

Question 7

Anabolism

Answer 7

Reactions in which smaller particles are linked together to form larger molecules

Question 8

Digestive tract (alimentary canal)

Answer 8

The tract that is “a tube within a tube” and includes: Pharynx, esophagus, stomach small intestine, and large intestine. Human digestion is extracellular, which means it happens outside your cells.

Question 9

absorption

Answer 9

The food monomers diffuse through the digestive tract into either the blood or lymph
