Pathways Intro Flashcards
glycogenolysis pathway & type
Catabolic:
glycogen -> glucose
(breakdown stored glycogen)
glycolysis pathway & type
Catabolic:
glucose -> pyruvate
pentose phosphate shunt pathway & type
Catabolic:
glucose converted to other sugars, especially ribose 5 phosphate
lipolysis pathway & type
Catabolic:
TAGs -> 3 FA + glycerol
Beta oxidation of fats pathway & type
Catabolic:
FAs -> acetyl CoA
glycogenesis pathway & type
anabolic:
glucose -> glycogen
gluconeogenesis pathway & type
anabolic:
non-CHO (alanine or lactate, some other AAs) -> glucose
Cholesterol synthesis pathway & type
anabolic:
acetyl CoA -> cholesterol
(acetyl CoA usually from glucose)
Fatty acid synthesis pathway & type
anabolic:
glucose -> palmitate
Kreb’s cycle pathway & type
Cellular respiration:
oxidation of fuels & production of reduced nucleotides, CO2 and GTP
what can enter the Kreb’s cycle?
CHO, FAs, and AAs
electron transport chain pathway & type
cellular respiration:
transduction of electrons from reduced nucleotides and production of ATP by proton motive force
What is the fate of pyruvate in muscle with oxygen?
mitochondria (Kreb’s & makes ATP in cytochrome chain)
what is the fate of pyruvate in muscle without oxygen?
lactic acid (Cori cycle) –> liver
what is the fate of pyruvate in muscle with transamination?
transports NH2 via alanine (enzyme: ALT/SGPT) from muscle breakdown –> liver, excreted as urea
