Glycolysis Flashcards
Step one
Glucose
Glucose process
Phosphorylation (ADP+ Pi =ATP)
step two
Glucose -6- phosphate
Glucose 6 phosphate
Issomerization
Step three
Fructose 6 phosphate
Fructose 6 phosphate
Phosphorylation
What is phosphorylation?
attaching the phosphate group to the ADP to make ATP
What’s the equation?
C6H12O6 —> C02 +H2O
What is isomerization?
rearranging the atoms
Substrate level phosphorylation, direct or not?
direct
oxidative phosphorylation, direct or not?
Indirect. energy from rxn is used elsewhere
Glycosis needs oxygen?
no, anaerobic
Pyruvate oxidation needs oxygen?
yes, aerobic
How much ATP is needed to start glycolysis
2, makes four, net 2
What is pyruvate?
Gives energy to cells during Krebs cycle
What does fructose 1,6 biphosphate turn into? (Two things)
DAHP and G3P
DAHP does what?
turns into G3P, making two of these total
What is the end goal of gycolysis?
2 pyruvate molecules
what happens to pyruvate?
3C pyruvate turns into 2C acetyl-CoA
Glycolysis makes how many ATPs total?
6, 2 direct 4 indirect
How many ATPs does pyruvate oxidation make?
6
how is pyruvate related to acetyl-CoA?
acetyl-CoA is pyruvate that’s been oxidized.
G3P then…
goes through a redox and makes two PEP
What is redox
The moving of electrons
What is chemiosmosis?
a pump shooting protons into the matrix and makes ATP as it falls back down through ATP synthase tunnel
step one pyruvate oxidation
goes into the mitochondria via doorway
step two pyruvate oxidation
CO2 removed
step three pyruvate oxidation
oxidation (removal of oxygen
step four of pyruvate oxidation
Coenzyme A bonds to the thing making Acetyl-CoA
