Glycosis Flashcards
where is glycolysis taking place in the cell
In the cytoplasm
beyond the first step in glycosis where are we in the cell
mitochondira
which is higher in the cytoplasm NAD, NADH
NAD
Which is higeher in the mitochondria NAD, NADH
NADH
One molecule of glucose requires how many moleculeS TO BREAK DOWN
2 NAD+
2ADP
2 Pi
Result of breakdown of glucose
2 pyruvate
2 NADH
2H+
2 ATP
2 H2O
which is absolutely requirwe to drive the metabolic pathway
NAD+
What happens if we do not have NAD+ in a metabolic pathway
it is not going to do normal.
what enzyme is responsible for converting pyruvate to L-lactate
lactate dehydrogenase
what happens if someone has a mutation of lactate dehydrogenase
glycolysis will come to an halt but there are alternate source for energy
what do decarboxylase do
remove a CO2 molecule
what enzyme converts pyruvate to acetaldehyde
pyruvate decarboxylase
acetaldehyde using alcohol dehydrogenase converts to
ethanol
why is arsenic toxic
it is a competitive inhibitor, because as more of arsenic is broken down, it enters into the glycolytic pathway and reaction comes to a halt. It is a gradual death
in animals, where is excess lactase taken to
the liver whihc converts back to glucose when needed
how does dietary starch and glycogen breakdown to glucose and dextrin
alpha-amylase through hydrolysis
glucose is converted to glucose-6-phosphate through
hexokinase
what cleaves dextrins to glucose
dextrinases
what takes up glucose to enter glycolysis
GLUT Transporters
carbohydrate stay around in pur body for how long
for about 24 hours before they are broken down
phosphorylase is converts stored starch and glycogen to
glucose-1-phosphate
the process of converting stored starch and glycogen to glusoce-1-phosphate is called
phosphorlysis
glucose-1phosphate is converted to glucose-6-phospahte through
phosphoglucomutase
phosphoglucomutase works analogously with
phosphoglycerate mutase by moving the Phosphate group from 3’C to 2’C
