17
Q

What is the substance that enters the small intestine

A

Chyme

18
Q

What promotes bowel movements

A

Buildup of waste in the large intestine (colon)

19
Q

What are the drawbacks of using antacids

A

Diharia and lots of constipation

20
Q

How does the liver assist in digestion

A

Creates bile and bile salts which emulsify fats (break them down)

21
Q

Is the liver mechanical or chemical digestion

A

Chemical since it breaks down fats

22
Q

Why are protein digesting enzymes often released in inactive form

A

They can harm the stomach or denature if they are overworked. They need HCL to to be activated.

23
Q

State two ways to increase the rate of enzyme reactions

A

Tempeture or pH

24
Q

Pepsinogen is activated by what substance in the stomach

A

HCL acid

25
Q

Why dont carbohydrates and lipases work in the stomach

A

Pepsin and HCL acid do not digest them. There is no other enzyme which does in the stomach.

26
Q

Three protein digesting enzymes

A

Gastric juices
Trypisn
Chrymotrypisn

27
Q

What chemically digests fats

A

Lipases and bile salts

28
Q

What enzyme digests starch

A

Salivary amylase
Pancreatic amylase

29
Q

All the enzymes are

A

Salivary amylase
Gastric juices
Pancreatic amylase
Lipases
Trypisn Chymotrpisn

30
Q

Three types of carbohydrates

A

Simple sugars
Monosaccarides
Disaccarides
Polysaccarides

31
Q

Fats break down into

A

Glycerol and three fatty acids

32
Q

Proteins break down into

A

Amino acids

33
Q

Enzymes are not killed by high heat but instead

A

Denatured by an inaccurate pH

34
Q

What does a catalyist do

A

Speeds up reactions just like enzymes

35
Q

The building of macromolecules are

A

Dehydration synthesis

36
Q

Food going down the wrong tube

A

Can be a spincter or esophgus problem

37
Q

Heartburn is a result of what and where

A

In the chest by eating too much or consuming unhealthy/ improper food

38
Q

What guards the enterence and exit of each digestive organ

A

Spincter

39
Q

What organizims live in the large intestine and produce vitamine B-12 and K

A

Bacteria

40
Q

If this organ was removed it would limit abosorbtion of nutirents
