Enzymes Flashcards
phosphorylates glucose to G6P so it cant leave the cell
hexokinase
breaks down glycogen into G1P so its usable
glycogen phorphorylase
-rate limiting enzyme
-as ADP increases its enzyme activity increases to sleep up glycolysis bc we need more ATP
-when lots of ATP available enzyme levels go down
(Regulated/inhibited by atp and adp conc)
phosphofructokinase (PFK)
facilitates pyruvate fermentation –> lactate in absence of O2
- NADH–NAD + H oxdizided in process
lactic acid —> H + lactate
lactate dehydrogenase
facilitates reaction : PCr + ADP –> ATP + Cr
(regulated by :
creatine kinase
regulated by substrate concentration
facilitates rxn in inner mito membrane:
pyruvate + NAD –> acetyl CoA + CO2 + NADH
pyruvate dehydrogenase
facilitates acetyl coA + oxaloacetate –> citrate
citrate synthase
more citrate sythase = more mitos in muscle
It catalyzes electron transfer from cytochrome c to molecular oxygen, conserving the released energy as a charge and proton gradient across the membrane in which it is located
cytochrome oxidase
moves fatty acyl coA from muscle cytosol –> mito matrix
carnitine palmitoyl transferase
the beta oxidation enzyme
result: 1 nadh (2.5 atp), 1 fadh (1.5 atp), 1 acetyl coA (10 atp)
beta HAD
facilitates ADP + Pi –ATP
atp synthase
break down tgs into 3 FAs and 1 glycerol
enzyme that regulate lypolysis: (in adipose and muscle)
hormone sensitive lipase (HSL)
ATP–> camp
Adenylate cyclase
