Blood Glucose
Science: KS3, topic 1.6.35
Controlling Blood Glucose Levels
It is important for an organism to keep its blood glucose levels within a small range.
Too little glucose
- Glucose is important for respiration.
- Respiration releases the energy needed by every living cell.
- If there is not enough glucose, an organism cannot produce enough energy.
Too much glucose
- If blood glucose levels are too high, this can have a negative impact on osmosis (movement of water between cells) by affecting concentration gradients.
