Controlling Blood Glucose Levels
It's important to keep blood glucose levels within a small range (for humans, between 6-8 mmol/dm3).
Too little glucose
- Glucose is important for respiration - the process that releases the energy needed by every living cell.
- Organisms can't produce enough energy if they don't have enough glucose.
Too much glucose
- This can have a negative impact on osmosis (movement of water between cells) by affecting concentration gradients.
