Integration of Metabolism Flashcards
Which of the following dietary nutrients would most rapidly reverse a state of ketosis in a starving person?
a. Fat
b. Protein
c. Amino acids
d. Carbohydrate
d.Carbohydrate
How soon would death occur from starvation if the body was unable to shift to a state of ketosis?
Within 3 weeks
Which of the following is used to supply some of the fuel needed by the brain only after the body has been fasting for a while?
a. Ketones
b. Glycerol
c. Fatty acids
d. Amino acids
Ketones
Elizabeth has been fasting for 4 days in observance of her religious beliefs. You note that her breath smells “fruity.” This is most likely due to
her body’s shift to a state of ketosis
How are ketones formed?
Condensation of acetyl CoA molecules
All of the following are general features of starvation in people except
a. a decrease in metabolic rate.
b. a decrease in mental alertness.
c. a decrease in immune function.
d. a decrease in body temperature.
b. a decrease in mental alertness.
Absorptive State
Four house after a meal. Time eating, digesting, and absorbing nutrients. Causes and increase of glucose, triglycerides, and amino acids in the blood.
Postabsorptive state
Time between meals. Body relies on stored nutrients in order to maintain homeostasis.
When the muscle releases alanine during the postabsorptive state, what is its function?
Its converted to glucose through the ornithine cycle
In the postabsorptive state, which of these does not occur in the liver:
a. glucose release
b. de novo gluconeogenesis
c. alanine release
d. fatty acid oxidation
c. alanine release
In the postabsorptive state, which of these does not occur in the adipose tissue:
a. lipolysis
b. fatty acid release
c. glycerol release
d. TG synthesis
d. TG synthesis
What is produced to carry TAG in the fasted/postabsorptive state
VLDL
Which hormone specifically hydrolyses TAG stored within adipose tissue
hormone sensitive lipase
What is FA bound to in the blood to prevent coalescing
albumin
