21
Q

What is metabolism?

A

the chemical transformation within cells of all living organisms

22

25
Q

What is insulin resistance?

A

26
Q

What is fiber?

A

Exclusively a plant nutrient. No universally accepted definition. Creates bulk in stool

27
Q

What is digestion?

A

The process of breaking down food by mechanical and chemical action into useable substances

28
Q

What is absorption, and which part of the digestive system does this occur?

A

Where nutrients pass from the intestines into the blood or lymph. The Jejunum.

29
Q

What is bile’s three functions in the digestion process?

A

Alkalinizes chyme (from an acid state), emulsifies fats, lubricates intestines

30
Q

What is the liver’s main role?

A

Filters out toxins and nutrients after absorption and before transport to cells for use

31
Q

Anabolism

A

Building up

32
Q

Catabolism

A

Breaking down

33
Q

How are enzymes typically names?

A

After the substances they break down using “ase” (ie:L Lactose, lactase)

34
Q

What are the 2 functions of the gallbladder?

A

concentrate and store bile, release bile into the duodenum to aid in digestion

35
Q

What is the function of the esophagus?

A

To propel food using a cylindrical muscle action (called peristalsis)

36
Q
