Which macronutrient is a quick source of energy?

What are carbohydrates?


This is not digestible, so it doesn't provide energy but it does help your digestive system stay healthy.

What is fiber?


The start of chemical digestion when this breaks down starches in the mouth.

What is saliva?


This is when each process can happen.

When is any time (CR) & during the day/with light (P)?

Tiny finger shaped structures that cover the inner surface of the small intestine
What are villi?

This macronutrient creates three major products within the human body:

enzymes, antibodies, & muscle fibers

What are proteins?

Energy released by nutrients is measured in units of these
What are calories?
Organs like the pancreas & liver help digestion by creating...

What are enzymes?


The place where cellular respiration & photosynthesis happen.

Where is mitochondria (CR) & chloroplasts (P)?

Involuntary waves of muscle contraction that push food through the digestive system
What is peristalsis?

The types of fats are...

What are unsaturated, saturated, & trans fats.


These are two rules to follow to avoid foodbourne illnesses.

What is: wash your hands to avoid spreading bacteria from one food to another (or from your hands to your mouth while eating) & refrigerate foods within two hours of cooking (to keep bacteria found in foods from multiplying).


This object begins the process of mechanical digestion in the mouth

What are teeth?


This is the type of cell that can undergo each process.

What is plant & animal cells (CR) & only plant cells (P)?

What are complex carbs?


These are good food sources for each macronutrient.

What is nuts/vegetable oils for lipids, chicken and fish for protein, fruit for carbohydrates.


This breaks down food & kills many bacteria that are swallowed with food.

What is hydrochloric acid?


This is the reactant that makes cellular respiration much more efficient.

What is oxygen (O2)?


These are the 3 ways energy intake & energy expenditure affect body weight.

What is:

energy intake>energy expenditure = weight gain.

energy intake<energy expenditure = weight loss.

energy intake=energy expenditure = same weight.


Nutrients not made by living things

What are minerals?


This is the difference between a food allergy & an intolerance.

What is a food allergy causes the body to have an immune response because the body believes it is a harmful substance (when it really isn't) a food intolerance is when a person can't properly digest a food.


These are four ways that bacteria help complete digestion.

What are:

producing vitamins, controlling the growth of harmful bacteria, breaking down things the digestive can't on its own (plant matter), & breaking down toxins in the large intestine.


These are the products of each reaction.

What is ATP, CO2, & H2O (CR) and glucose (C6H12O6) & O2 (P)?


These are the three common causes of foodbourne illness.

What are viruses, bacteria, & parasites?
