Digestive Pathway
Where digestion begins
Mouth
Does digestion occur in the esophagus?
No
These elements make up carbohydrates.
carbon, hydrogen, and oxygen?
This chemical tests for starch.
Iodine
Most feces are made of this.
Fiber and water
Food moves through this tube after leaving the mouth.
Esophagus
The main job of the esophagus.
Transporting food from mouth to stomach
The smallest, simplest carbohydrate studied.
Glucose
This solution tests for glucose (simple sugars).
Benedicts
What would Benedict’s solution show in feces for M'Kenna (what color)
It would show up orange because there is glucose present.
This organ mixes food with acids and enzymes
stomach
This process breaks large molecules into smaller ones.
Digestion
A complex carbohydrate made of many glucose units.
Starch
The lab tool that models a membrane. (small intestine)
Dialysis Tubing
How you can tell from the graph that nutrients were absorbed.
Levels decrease
Most nutrient absorption happens here.
Small Intestine
This type of digestion uses enzymes.
Chemical
The largest complex carbohydrate studied in class.
Starch
Iodine turns this color when starch is present.
Black or deep purple
Why glucose “disappears” in the small intestine.
What is it is absorbed into the bloodstream through the intestinal walls?
This organ absorbs water and forms feces.
Large Intestine
This type of digestion involves mechanical breakdown.
physical
This type of carbohydrate must be broken down before absorption.
Complex Carb
Benedicts starts off as what color and shows up as what color when glucose is present?
Blue to orange/brown
What enzyme breaks down carbs in spit
Amylase
