Worked Solution & Example Answer:Describe the process of glycolysis - AQA - A-Level Biology - Question 1 - 2021 - Paper 2
Step 1
Describe the process of glycolysis.
Answer
- Phosphorylation of glucose using ATP, leading to the formation of glucose-6-phosphate.
- Oxidation of triose phosphate to form pyruvate, involving the conversion of glyceraldehyde-3-phosphate.
- There is a net gain of ATP due to the production of four ATP molecules against the two used, yielding a net gain of two ATP.
- NAD is reduced to form NADH, capturing the electrons generated during the oxidation steps.
