used correct answers In the *first five steps of glycolysis*, is ATP used or generated?
glucose-6-phosphat...
phosphorylation reactions correct answers What type of reactions does a *kinase* catalyze?
fructose-2,6,-biphosphate (F2,6P) ; phosphofructokinase(-2) correct answers What is the most
important *activator of glycolysis* in mammals?
Which enzyme does it speed up?
dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate (GAP) correct answers In
*step 4 of glycolysis*, fructose-1,6-bisphsphate (FBP) is cleaved into what two molecules?
,triose phosphate isomerase enzyme catalyzes the conversion of dihydroxyacetone phosphate
(DHAP) to glyceraldehyde-3-phosphate (GAP), and vice versa correct answers What occurs
during *step 5 of glycolysis*?
used; two correct answers In *steps 1-5 of glycolysis*, is ATP used or produced?
How many ATPs?
glyeraldehyde-3-phosphate (GAP) correct answers Identify this molecule
1,3-biphosphoglycerate (1,3-BPG) correct answers Identify this molecule
3-phosphoglycerate correct answers Identify this molecule
2-phosphoglycerate correct answers Identify this molecule
phosphoenolpyruvate (PEP) correct answers Identify this molecule
pyruvate correct answers Identify this molecule
glyceraldehyde-3-phosphate (GAP) to 1,3-biphosphoglycerate (1,3-BPG); step 6 correct answers
The conversion between which two species is involved in converting NAD+ to NADH during
*glycolysis*?
Which numbered step is this?
steps 7 and 10 correct answers In which steps of *glycolysis* are molecules of ATP produced?
produced; four correct answers In *steps 6-10 of glycolysis*, is ATP used or produced?
How many ATPs?
two correct answers In the overall process of *glycolysis*, how many ATP molecules are
formed?
steps 1, 3, and 10; largely negative (-) deltaG correct answers Which steps of *glycolysis* are
considered irreversible?
Why is this so?
lactate; NAD+ need of continued glycolysis is unsustained, pyruvate is temporarily converted to
lactate *to create more NAD+* correct answers During exercise, pyruvate can be converted to
[?].
Why does this occur?
ethanol; to create more NAD+ under anaerobic conditions (without oxygen) correct answers In
fermentation, pyruvate can be converted to [?].
