Glycolysis

Question 1

Where does glycolysis occur

Answer 1

Cytoplasm

Question 2

What does glycolysis mean

Answer 2

Break down of glucose a 6 carbon molecule into two three carbon pyruvate

Question 3

First step of glycolysis

Answer 3

Phosphorylation - Glucose gains two phosphate groups donated from two ATP’s to become hexose biphosphate and 2 ADP.

Question 4

What occurs next in phosphorylation

Answer 4

Hexose bisphosphate splits into two to become triose phosphate (x2) and another 2 phosphates, from the cytoplasm, are added onto the triose phosphates, becomeing triose bisphosphates (x2)

Question 5

What happens in the final stage of glycolysis (oxidation)

Answer 5

Triose bisphosphate is converted into pyruvate (x2). 2 ADP comes to collect the phosphate groups that were originally bound to the triose phosphate. 2 ADP for one pyruvate, 2 ADP for the other. NAD also steals a H atom from the triose bisphosphate to become reduced NAD which occurs at both pyruvate stages. By the end we get pyruvate which gets transported to mitochondria for aerobic respiration

Question 6

What is substrate level phosphorylation

Answer 6

ATP production without use of electron transport chain and ATP synthase

Question 7

What are the products of glycolysis

Answer 7

2 pyruvate
2 ATP
2 Red. NAD
