(Answered) 202 Questions and Correct
Answers, 100% Correct. Updated
2024/2025.
fructose can be turned into
glucose
sucrose is
fructose + glucose
lactose is
glucose + galactose
galactose can be turned into
glucose
excess nutrients are stored as
fats
neurons only use what carb
glucose
muscle energy sources
FA + glc (like FA more)
other organs energy sources
glc over fat
do you need ATP to move glucose into a cell
yes
glycogen is mostly stored in
the liver, but some in the muscle
does muscle have the enzyme to turn g6p into glucose?
no, must produce lactate and release it into blood for liver to do rev. glyc
metabolism: look at the pathway on your notes
,glcn:glc1p:glc6p:frc-6p:glc-3p x2: pyr x2
can you use AAs for energy and where
yes - make pyruvate from AA and rev. glyc to glc = gluconeogenesis
can also just go through tca
is there lots of energy in fat?
yes
in an absorptive state, glucose does what in muscle
stored as glcn
in an absorptive state, glucose does what in tissues
turned into energy
in an absorptive state, glucose does what in th eliver
stored as glcn, or made into triglycerides and then stored in fat
in an absorptive state, triglycerides are stored where
adipose tissue (FA)
in an absorptive state, AA do what in the muscle
build proteins
in an absorptive state, aa do what in the liver
turned into energy
in a post absorptive state, what happens in the liver
move glcn to glucose and release so brain has glucose
in post-abs state, muscle does what
glcn to lactate/pyruvate to liver for gluconeogenesis (to brain)
in post-abs state, FA move into?
the muscle and other tiisues for energy
in post-abs state, glycerol moves into?
, liver to be turned into glucose
in post-abs state, muscle's proteins will
degrade and be moved into liver
what are the receptors on mit and nucleus for regarding thyroid hormone
T3
enzyme that converts t4 into t3
deiodinase
why do we even have t4
long half life
no thyroid?
decrease bmr
tsh is released from
anterior pituitary
what releases tsh
trh
thyroid hormone mechanism of action
bind receptor, remove hsp90, bind TRE region w/ zinc fingers, cause protein synthesis for enzymes
involved in glycolysis
where else does t3 act in the cell
mitochondria (enz for resp)
Thyroid hormone stimulates the synthesis of
GH, NGF, and PRL
thyroid hormone permissive effects
GH, NGF, epi
TH does what at night
decreases (why you feel cold)
TH increases with what activities
meals, exercise
diets do what to metabolism
