Pathways Flashcards
What is the first step of glycolysis
Glucose becomes Glucose 6 phosphate
what enzyme catalyzes the first step of glycolysis ?
hexokinase
What happens to ATP during first step of glycolysis
ATP to ADP
What is the second step of glycolysis ?
Glucose 6 phosphate convers to fructose 6 phosphate
What enzyme is responsible for the 2nd step of glycolysis ?
phophohexyl isomerase
What is the 3rd step of glycolysis
fructose 6-phosphate to
becomes fructose 1,6-bisphosphate
What enzyme is responsible for the 3rd step of glycolysis ?
Phosphfrutokinase PFK1
What is unique about the 3rd step of glycolisis ?
irreversible
What is the fourth step of glycolysis
Fructose 1,6-bisphosphate becomes glyceraldehyde 3-phosphate and dihydroxyacetone phosphate
What is unique about step 4 of glycosis
final prepatory phase of glycolysis
What is step 5 of glycolysis ?
glyceraldehyde 3-phosphate is oxidized and becomes 1,3-bisphosphoglycerate
What enzyme is responsible for step 5 of glycolysis ?
Glyceraldehyde 3-phosphate dehydrogenase
What is the firt step of gluconeogenesis
pyruvate is converted to oxaloacetate
What enzyme is responsible for the 1st stewp of gluconeogenesis ?
pyrubate carboxlase
Which 2 organs are resonsible for gluconeogenesis
liver and kidneys
What is the first step of the oxidative pentose phosphate pathway
Glucose-6-phosphate is oxidized to form lactone.
What is step 6 of glycolysis ?
1,3 bisphosphpylglycerate becomes 3 phospylglycerate
What enzyme is responsible for step 6 of glycolysis
phophyglycerate kinease
What is step 7 of glycolysis
3 phosphoglycerate becomes 2 phosphoglycerate
What enzyme is responsible for step 7
phosphoglycerate mutase
What is step 8 of glycolysis ?
2 phophylglcerate becomes phophylenolpyruvate
What enzyme is used in step 8 of glycolysis
enolase
What is step 9 of glycolysis
phopylenol pyruvate becomes pyruvate
enzyme for tep 9 of glycolysis
pyruvate kinase
What occurs to electron carrier in 1st step
NADP+ is reduced in NADPH
What are the intermediates of citric acid cycle ?
citrate, iso-citrate, alpha-ketoglutarate, succinate, fumarate, malate, and oxaloacetate)
Does glycolysis require oxygen ?
No
What is the 2nd step of oxidative phase of pentose phosphate
6 phosphylglucerate becomes ribulose 5 phosphate
What happens in non oxidative phase
ribulose 5 phosphate becomes ribose 5 phosphate
what is the next step of gluconeogenesis ?
oxaloacetate is converted to phophyenolpyruvate
What enyme is responsible for step 2 of gluconeogenesis ?
phophylenolpryruvate carboxalase
