Glycolysis

Question 1

Name the four stages of Respiration

Answer 1

Glycolysis
Links Reaction
Krebs Cycle
Electron Transport Chain

Question 2

What conditions does Glycolysis occur in?

Answer 2

Anaerobic

Question 3

What is the overall yield of glycolysis?

Answer 3

2 ATP
2 Reduced NAD
2 Pyruvate

Question 4

Describe the 4 stages of glycolysis

Answer 4

Glucose is phosphorylated to phosphorylated glucose by hydrolysis of ATP to ADP and PI which lowers the activation energy for enzyme-controlled reactions.

Phosphorylated glucose splits into 2x Triose Phosphate

Triose Phosphate is oxidised
H transferred to 2 NAD (overall)
Production of 2 ATP (overall)

Convert Triose phosphate to Pyruvate

Question 5

When Phosphorus is added, glucose becomes ______

How many ATP are required for this?

Answer 5

phosphorylated

2 ATP required

Question 6

What does phosphorylated glucose spilt into?

Answer 6

Triose Phosphate

Question 7

What does triose phosphate turn into via the removal of 2H and 2Pi?

Answer 7

Pyruvate

Question 8

Glycolysis occurs in all organisms- what is this evidence of ?

Answer 8

Evolution

Question 9

How many carbons does Pyruvate have?

Answer 9

3

Question 10

Where does Glycolysis occur?

Answer 10

In the cytoplasm
