integration of metabolism Flashcards
what can the brain metabolise?
.Glucose
.Keytone bodies
what can’t the brain metabolise?
fatty acids
define hypoglycemia
low glucose
define hyperglycemia
high sugar
what can the heart utilise for energy?
glucose
fatty acids
ketone bodies
what role does the liver play
lipoprotein metabolism storage organ (glycogen)
where are fatty acids stored
adipose tissues
During vigorous contractions, the muscle utilises energy from…
glucose
fatty acid oxidation
In order for pyruvate to be converted into acetyl coA, what much pyurvate undergo?
reduction
decarboxylation
what is gluconeogenisis
synthesis of glucose from pyruvate
which enzymes catalyse irreversible pathways that must be by passed for gluconeogenesis
Hexokinase, pyruvate kinase, phosphofructokinase
true or false: Fatty acids cannot be converted into glucose by gluconeogenesis
true
true or false: Fatty acids cant be converted into keytone bodies used by tissues such as brain and heart
false
During moderate exercise, how are increased demands of skeletal muscle for ATP met?
.Increased demands of glucose transported on the surface of muscle cells
. increased rate of gluconeogenesis induced by adrenalin
during STRENUOUS exercise, how are increased demands of skeletal muscle for ATP met?
.Glyconeogenesis in the liver
.conversion of pyrvate into lactate in the liver by lactate dsehydrogenase
