Glycolysis

Question 1

Steps of glycolysis

Answer 1

1. Priming reactions
2. Cleavage
3. Oxidation
4. ATP formation

Question 2

Priming reactions

Answer 2

• Two high energy phosphates from 2 ATP molecules are added to 6 carbon molecule glucose
• produces 6 carbon molecule with 2 phosphates

Question 3

What does glycolysis begin with?

Answer 3

The addition of energy`

Question 4

Cleavage

Answer 4

• 6 carbon molecule with 2 phosphates is split in 2

- forms 2 3-carbon sugar phosphates

Question 5

Oxidation

Answer 5

• additional inorganic phosphate incorporated into each 3 carbon phosphate
• oxidation reaction converts the 2 sugar phosphates into intermediates that can transfer a phosphate to ADP to from ATP
• oxidation reactions also yield NADH

Question 6

ATP formation

Answer 6

• oxidation reaction converts the 2 sugar phosphates into intermediates that can transfer a phosphate to ADP to from ATP
• net energy yield of 2 ATP and 2 NADH

Question 7

What is the net yield of glycolysis

Answer 7

2 ATP

2 NADH

Question 8

substrate level phosphorylation

Answer 8

enzyme transfers inorganic phosphate from to ADP to for ATP

ex: PEP gives phosphate to ADP to make pyruvate and ATP
