Lesson details
Key learning points
- If conditions in the body change too much this can be dangerous to our health.
- Changes in body temperature affect the rate of chemical reactions and can impact enzyme activity.
- Changes in body temperature can lead to hypo- or hyperthermia and death.
- Changes in water balance in the body can lead to dehydration and death.
- Use of antagonistic effects to maintain a constant environment.
Common misconception
It is common for pupils to misunderstand the links between increased or decreased body temperature and the impact on enzyme function.
Explanations of the effect of temperature on enzyme activity, the link between body temperature and enzyme function, and conditions such as hyper- and hypo-thermia are made and explored in this lesson.
Keywords
Enzyme - a protein which acts as a biological catalyst
Internal body temperature - the optimal internal temperature of our body, which is about 37°C
Homeostasis - the regulation of the internal conditions to maintain optimum conditions for enzyme action and all cell functions
Antagonistic - effectors and effects that work against each other
Equipment
Optional: Bunsen burner, tripod, gauze, heat proof mat, thermometer, beaker, ice cubes.
