Insulin and the control of blood sugar level
I can describe the role of the hormone insulin in controlling blood sugar level.
Insulin and the control of blood sugar level
I can describe the role of the hormone insulin in controlling blood sugar level.
Lesson details
Key learning points
- If conditions in the body change too much this can be dangerous to our health (e.g. enzymes).
- Homeostasis is the regulation of internal conditions for optimum enzyme activity.
- Glucose travels in the blood plasma and is delivered to cells for aerobic respiration.
- The hormone insulin helps to keep human blood sugar level constant.
- The pancreas secretes insulin when blood sugar level is too high; it causes liver cells to convert glucose to glycogen.
Common misconception
Not linking the idea that glucose concentration is important for cellular respiration, even during times of rest.
There are a selection of slides in LC2 that specifically link glucose and respiration and discuss the idea of respiration occurring during rest.
Keywords
Homeostasis - homeostasis is the regulation of the internal conditions to maintain optimum conditions for enzyme action and all cell functions
Respiration - a chemical reaction in living organisms that releases energy from glucose
Insulin - a hormone secreted by the pancreas when blood glucose is too high, lowering blood glucose levels
Glucose - a sugar that travels in the blood and is supplied to cells for respiration
Glycogen - a stored form of glucose found in liver and muscle cells
