40 Question Teacher Guide Digestion Flashcards
Which macrocolecule stores the most energy
Carbohydrates
Which macromoleucle type is most easily burned by the body
Carbohydrates
Name the reaction type for the breakdown of any food/ macrocolcule
Hydrolysis
Where does chemical digestion begin
In the mouth using salivary amylase
Where does chemical digestion end
Small intestine
Which organs use enzymes to digest all macromolecules
Pancreas, stomach, mouth, small intestine
Which types of digestion occor in the stomach
Chemical: Gastric juices HCL and pepsin breaking down protein
Physical: Stomach ruage churning food
Three reasons why the stomach does not digest itself
Gastric juices will not be secreted until there food present
Mucus lining
Pepsins will be inactive until food is prsent
How is the small intestine adapted to its function
Breaks down everything to its simplest form
What is the significants of the lactal
Takes fat by diffusing through the small intestine cells. Which is taken into the lymph vessiles take it to the chest area
What does the large intestine do
Absorbs water
Gets rid of waste
Stores waste
Has bacteria that systhesis with B-12 and K
What type of action is responsible for movement in the digestive system
Persalisis
Where does high nutrient blood go from the small inestine
Goes to the liver
What is the significance of the esophagus
Used to get the bolis into the digestive system
What triggers gastric secrections to stop
Phyloric spincter
What substance enters the stomach
Bolis
What is the substance that enters the small intestine
Chyme
What promotes bowel movements
Buildup of waste in the large intestine (colon)
What are the drawbacks of using antacids
Diharia and lots of constipation
How does the liver assist in digestion
Creates bile and bile salts which emulsify fats (break them down)
Is the liver mechanical or chemical digestion
Chemical since it breaks down fats
Why are protein digesting enzymes often released in inactive form
They can harm the stomach or denature if they are overworked. They need HCL to to be activated.
State two ways to increase the rate of enzyme reactions
Tempeture or pH
Pepsinogen is activated by what substance in the stomach
HCL acid
Why dont carbohydrates and lipases work in the stomach
Pepsin and HCL acid do not digest them. There is no other enzyme which does in the stomach.
Three protein digesting enzymes
Gastric juices
Trypisn
Chrymotrypisn
What chemically digests fats
Lipases and bile salts
What enzyme digests starch
Salivary amylase
Pancreatic amylase
All the enzymes are
Salivary amylase
Gastric juices
Pancreatic amylase
Lipases
Trypisn Chymotrpisn
Three types of carbohydrates
Simple sugars
Monosaccarides
Disaccarides
Polysaccarides
Fats break down into
Glycerol and three fatty acids
Proteins break down into
Amino acids
Enzymes are not killed by high heat but instead
Denatured by an inaccurate pH
What does a catalyist do
Speeds up reactions just like enzymes
The building of macromolecules are
Dehydration synthesis
Food going down the wrong tube
Can be a spincter or esophgus problem
Heartburn is a result of what and where
In the chest by eating too much or consuming unhealthy/ improper food
What guards the enterence and exit of each digestive organ
Spincter
What organizims live in the large intestine and produce vitamine B-12 and K
Bacteria
If this organ was removed it would limit abosorbtion of nutirents
Small intestine
