Suggest how each of these factors would affect the concentration of glucose in the blood;

1. Time since last meal
2. Types of food eaten during the last meaql
3. Amount of recent exercise

1. Time since last meal: The longer it has been since the last meal, the lower the concentration of glucose in the blood as it is used up by the body for energy. However, if it has been a very long time since eating, blood glucose levels may drop too low.

2. Types of food eaten during the last meal: Foods high in sugar and carbohydrates will cause blood glucose levels to rise quickly, while foods high in protein and fiber will cause a more gradual increase. Eating a large amount of high-sugar foods can lead to a spike in blood glucose levels, while a balanced meal will help maintain stable levels.

3. Amount of recent exercise: Exercise can lower blood glucose levels by increasing the muscles' uptake of glucose for energy. However, intense exercise can also cause a temporary increase in blood glucose levels due to the release of stress hormones. Regular exercise can help regulate blood glucose levels over time.
