Worked Solution & Example Answer:The list shows some of the substances produced during the respiration of glucose in the presence of oxygen - Scottish Highers Human Biology - Question 8 - 2018
Step 1
Which of the following sequences shows the order in which these substances are produced?
Answer
The correct order of production during the respiration of glucose in the presence of oxygen is as follows:
- Pyruvate (produced from glycolysis)
- Acetyl group (produced from the decarboxylation of pyruvate)
- Citrate (formed as acetyl CoA combines with oxaloacetate in the Krebs cycle)
- ATP (produced through substrate-level phosphorylation and oxidative phosphorylation)
Therefore, the correct sequence is represented by option A: 4, 2, 1, 3.
