Glycolysis Flashcards
What are the two processes that make up metabolism?
catabolism
anabolism
d: metabolism
the chemical processes that occur within a living organism in order to maintain life
d: anabolism
the synthesis of complex molecules in living organisms from simpler ones together with the storage of energy; constructive metabolism
d: catabolism
the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy; destructive metabolism.
is anabolism oxidative/reductive and exergonic/endergonic?
reductive and endergonic
What carbohydrate is our primary energy source?
glucose
What is oxidation of glucose through aerobic glycolysis used for?
pyruvate
What is glucose produced by fermentation of anaerobic glycolysis used for?
lactate
What is oxidation through the pentose phosphate pathway used for?
ribose-5-phosphate
what is excess glucose produced used for?
storage
why cant glucose be stored as glucose?
as metabolises too fast so cant be stored
How does glucose get into the cell?
via facilitated diffusion via GLUTs
what are the 2 major cellular needs of glucose?
production of ATP
provision of building blocks for synthetic reactions
What are the 3 control points in glycolysis?
hexokinase
phosphofructokinase
pyruvate Kinase
what enzyme controls the rate of substrate movement?
phosphofructokinase
