3 Questions
What is homeostasis in mammals?
The maintenance of stable internal environment within restricted limits.
What are the examples of homeostasis mentioned in the text?
Core temperature, blood pH, blood glucose concentration, and blood water potential.
What happens when blood glucose concentration is too high?
Dehydration occurs.
Study Notes
- Homeostasis in mammals is the maintenance of stable internal environment within restricted limits.
- Examples of homeostasis include core temperature, blood pH, blood glucose concentration, and blood water potential.
- Enzymes have an optimum temperature and pH.
- Maintenance of a stable core temperature and blood pH is important for enzyme activity.
- Physiological control systems normally involve negative feedback.
- Too high or too low blood pH can cause enzymes to denature and fewer enzyme-substrate complexes.
- Too low blood glucose concentration can result in less ATP produced and cell death.
- Too high blood glucose concentration can cause dehydration.
- Water potential of blood decreases when blood glucose concentration is too high.
- Kidneys can't absorb all glucose causing more water to be lost in urine.
Test your knowledge on the importance of homeostasis in maintaining a stable internal environment in mammals. Learn about the examples of homeostasis, the role of enzymes, and the negative feedback involved in physiological control systems. Discover the consequences of imbalances in core temperature, blood pH, blood glucose concentration, and blood water potential.
