Metabolic syndrome puts a person at risk for which chronic diseases? -
ANSWER heart disease, diabetes, and stroke
what is salivary amylase? - ANSWER -enzyme that begins starch digestion in
the mouth
-breaks down starch into many smaller units
describe the process of carbohydrate digestion - ANSWER 1. Mouth: some
starch is broken down to maltose by salivary amylase
2. Stomach: salivary amylase is inactivated by strong acid in the stomach. no
further digestion occurs in the stomach
3. Pancreas: enzymes (amylase) from pancreas break down starch into
maltose in the small intestine
4. Small intestine: enzymes in the wall of the small intestine break down the
disaccharides sucrose, lactose, and maltose into mono saccharides glucose,
fructose, and galactose
5. Absorption of glucose, fructose and galactose into blood to be taken to
the liver via a portal vein
6. Large intestine: viscous fiber is fermented into various acids and gases by
bacteria in the large intestine
, 7. Rectum and anus: nonfermentable fiber escapes digestion and is excreted
in feces but little other dietary carbohydrate remains
where is glycogen stored? - ANSWER liver and muscles
what is a polysaccharide? - ANSWER numerous single sugar units bonded
together to form a chain. also called complex carbohydrates or starch
what is high-fructose corn syrup? - ANSWER corn syrup that has been
manufactured to contain between 42% and 90% fructose. most commonly
found in soft drinks, candies, jams, jellies and many other fruit products and
desserts
why does the body need glucose? - ANSWER it is an important source of
energy for human cells
what causes type 1 diabetes? - ANSWER when the pancreas doesn't produce
enough insulin so the blood glucose level becomes too high
what is sucrose? - ANSWER glucose + fructose
-found in sugarcane, sugar beets, honey, and maple sugar
