Study Notes
- When food is digested, complex carbohydrates are broken down into glucose, the simplest form of sugar, which is quickly absorbed into the bloodstream to provide energy for cells in the brain and nervous system.
- Glucose levels in the blood can be measured with a simple blood test, with a normal concentration being around five millimoles per liter.
- Consuming a liter of fruit juice with 100 grams of glucose can raise blood sugar levels to around 8 millimoles per liter within 15 minutes.
- Physical activity, such as cycling, can help lower blood sugar levels by using up glucose as an energy source for the muscles.
- The liver and pancreas play key roles in regulating blood sugar levels: the pancreas releases insulin to store excess glucose as glycogen in the liver, while glucagon is released when blood sugar levels are too low to convert stored glycogen back into glucose.
