Worked Solution & Example Answer:Short-term starvation affects the levels of blood glucose, liver glycogen, the hormones insulin and glucagon - OCR Gateway - GCSE Biology - Question 15 - 2020 - Paper 1
Step 1
Which line on the graph represents the level of glucagon in the blood during short-term starvation?
Answer
During short-term starvation, the level of glucagon in the blood increases.
Based on the graph provided, line A represents this increase in glucagon. It is essential to note that glucagon's primary role is to promote the release of glucose from liver glycogen into the bloodstream when blood glucose levels are low.
As the duration of starvation extends, the body's need for glucose rises, leading to higher glucagon levels, which line A clearly illustrates.
