nutrition and metabolism Flashcards
what is a calorie (c)?
amount of energy needed to raise 1 gram of water 1 degree c (1gram/1mL)
how many c are in a C?
kilocalories in a calorie=1,000
what is glycogenesis?
the storing of sugar in the form of glycogen for the body to use later
what is the enzyme that catalyzes the phosphorylation of glucose
hexokinase
how does glycogen synthesis store glycogen?
through dehydration synthesis
what is glycogenolysis stimulated by?
glucagon and epimotrin
what does glycogen phoshorilase use to use the energy?
hydrolisis
what enzyme takes the phosphate off to use throughout the body?
glucose phosphatase
what is lipogenesis?
the metabolic formation of fat
(PGAL creates glycerol, acetyl CoA can create fatty acids)
what is glycoheogenesis?
formation of sugar from non-carbs
what is PGAL and fatty acids broken down into?
ketone bodies or acetyl CoA groups
what is gluconeogenesis?
The process of making glucose from its own breakdown products or from the breakdown products of proteins. (amine group)
what happens at the liver in the storage of protein?
glutonic acid is deaminated to ammonia (nh3) then converted into urea (costs ATP)
