Question 8

What is the result of Glycolysis?

Answer 8

2 ATP, 2 NADH and 2 Pyruvate

Question 9

How many % of free energy that can be released by glucose gets released in glycolysis?

Answer 9

5,2%

Question 10

How many stages are there in glycolysis and what happens in them in short?

Answer 10

There are two stages to Glycolysis

Stage 1:
- Preparation stage (reaction 1 to 5) Glucose is phosphorylated and converted to fructose which is again phosphorylated and cleavated into two molecules of glyceraldehyde-3-phosphate. For this to occur there is an investment of two molecules of ATP.

Stage 2:
- Finishing stage (reactions 6 - 10) The two molecules of glyceraldehyde-3-phosphate are converted to pyruvate and 4 ATP and 2 NADH are created.

Question 11

What are the three steps of glycolysis?

Answer 11

• Hexokinase
• Phosphofructokinase
• Pyruvate kinase

Question 12

Where does the gluconeogenesis occur?

Answer 12

It occurs mainly the liver and to a limited extent in the kidney and small intestine under some conditions

Question 13

What is the result of gluconeogenesis?

Answer 13

Glucose, 2 NAD+, 4 ADP, 2 GDP and 6 Pi
