Worked Solution & Example Answer:The diagram shows a capillary inside liver tissue - OCR Gateway - GCSE Biology - Question 5 - 2021 - Paper 1
Step 1
What does the arrow represent?
Answer
The arrow in the diagram indicates the movement of gases through the capillary. Given the context of liver cell activity and gas exchange, the most logical interpretation is that the arrow represents oxygen diffusing into a liver cell. This is essential for cellular respiration, which requires oxygen to produce energy. Therefore, the correct answer is C: Oxygen diffusing into a liver cell.
