Nutrition 1020 Exam 3 Weber State
QUESTIONS WITH ANSWERS
Mechanical digestion - CORRECT ANSWERS ✔✔The
breaking down of big food parts into smaller ones,
involving muscles and nerves. Chewing(mastication)
Chemical digestion - CORRECT ANSWERS ✔✔The
breaking down of big food parts into smaller ones,
involving acid, enzymes, and hormones. Saliva and
amylase(breaks down carbs).
What is an Enzyme? - CORRECT ANSWERS ✔✔Protein that
catalyze metabolic reactions, and are necessary for most
biochemical reactions to occur.
Examples of enzymes - CORRECT ANSWERS
✔✔amylase:carbohydrates
protease:proteins
lipase: Lipids/Fats
What is a Hormone? - CORRECT ANSWERS ✔✔Chemicals
produced by cells, and secreted, then affect the behavior

, Examples of hormones and purpose? - CORRECT
ANSWERS ✔✔Secretin: released from duodenal cells and
sends signals to the pancreas to secrete digestive
enzymes to the stomach to produce pepsin, a protease
enzyme, and to the liver to produce bile.
Cholecystokinin: released form duodenal cells and sends
signals to the pancreas to secrete digestive enzymes to
the gallbladder to release bile.
Peristalsis - CORRECT ANSWERS ✔✔a muscular wave
action that occurs throughout the intestinal tract.
Stomach - CORRECT ANSWERS ✔✔muscular organ and
storage reservoir. It mechanically digests food by mixing
and churning. Chemically digests food with acid and some
enzymes(pepsin). The food then becomes chyme
Small Intestine Order - CORRECT ANSWERS
✔✔Duodenum
Jejunum
Ileum
The 3 accessory Organs and functions - CORRECT
