Constant Internal Environment Flashcards
What does metabolic efficiency rely on?
- Temperature
- pH
- water and salt concentration
- absence of toxins
Nick
What does very low temperatures do to cells?
Very low temperatures could freeze the water in the cells
Nick
What does very high temperature do to the cells?
Very high temperatures causes enzymes and other proteins to denature
Nick
What is the importance of temperature and pH
Keenan & Brooke
They can only function within a narrow range or temperature & pH
What’s the problem of the build up of carbon dioxide?
It may be toxic to cells and affect enzymes either directly or indirectly
Nick
What is the fluid that surrounds each cell?
It is surrounded by intercellular or interstitial fluid
Nick
How can toxins directly impact enzymes?
By blocking the active sight of enzymes.

How can toxins indirectly impact enzymes?
By altering the optimal conditions for enzyme functioning. e.g. co2 alters pH of fluid)
