Card preview (22)
where does glycolysis occur
in cytoplasm of all cells
whats unique about glycolysis
does not require oxygen
what actually happens like end goal of glycolysis
one glucose is converted into two pyruvate mols (3C each)
what are the 3 like ‘titles’ for the steps of glycolysis
phosphorylation of glucose splitting oxidation
what happens in step 1 - phosphorylation of glucose
glucose - glucose phosphate 2 ATP used to add 2 phosphate groups forms hexose biphosphate (6C)
what happens in step 2 - splitting
6 C splits into two triose phosphate (TP)
what happens in step 3 - oxidation
each tp oxidised to pyruvate 2 NAD reduced to NADH 4 ATP produced by substrate level phosphorylation
what is the end products of glycolysis
2 NET ATP 2 NADH 2 pyruvate
how many net ATP at end of glycolysis
2
how many NADH at end of glycolysis
2
how many pyruvate produced in glycolysis
2
where does glycolysis occur
cytoplasm
is oxygen required (glycolysis)
no
why does glycolysis not happen in the matrix of the mitochondria
all needed enzymes required are located in the cytoplasm
what does glucose phosphorylation mean
addition of phosphate group
which molecule gets reduced in glycolysis
NAD
name process of removing hydrogen atoms
dehydrogenation
which enzyme catalyses dehydrogenation
dehydrogenase
how many ATP is produced during glycolysis
4
which sort of phosphorylation is involved in glycolysis
substrate level phosphorylation
how many ATP molecules are used
2
name the final product of glycolysis and what happens next to it
pyruvate diffuses into mitochondria
