New cards

Isoenzymes

Allow the function of an enzyme to work under various conditions / stages

2
New cards

3 irreversible enzymes of glycolysis

Hexokinase

Phosphofructokinase

Pyruvate kinase

3
New cards

What does the negative delta G of glycolysis mean

Irreversible

4
New cards

Role of glycolytic pathway

Degrade glucose to generate ATP

5
New cards

What does phosphorylation do to the charge of glucose

Confers a negative charge so it can no longer cross the membrane

6
New cards

What is hexokinase initiated by

G-6-P

7
New cards

What is reaction 3 of glycolysis

ATP driven phosphorylation of fructose-6-phosphate

8
New cards

What is PFK-1 inhibited by

ATP

9
New cards

In stage 3 glycolysis, what converts between ADP, ATP, AMP

Adenylyl kinase

10
New cards

Reaction 10 of glycolysis

Pyruvate kinase mediates transfer of a phosphoryl from phosphoenolpyruvate to ADP to make ATP and pyruvate

11
New cards

What ion stimulates step 10 glycolysis

K+

12
New cards

What ion is needed for step 10 glycolysis

Mg2+
