Study Notes
Enzyme Activity and pH
- Enzyme activity is affected by extreme pH values, where it decreases or becomes inactive at values that are too high or too low.
- Maintaining the appropriate pH is important for enzyme function as it allows the enzyme to maintain its native shape and perform its biological function.
Temperature and Enzyme Activity
- Temperature affects enzyme activity, with optimal temperatures allowing for maximum activity.
- Temperatures above the optimal range can lead to denaturation of the enzyme, resulting in a loss of function.
- Maintaining the appropriate temperature is important for enzyme function as it allows the enzyme to maintain its native shape and perform its biological function.
Importance of Temperature and pH for Enzyme Function
- Maintaining the appropriate temperature and pH is important for enzyme function as it allows the enzyme to maintain its native shape and perform its biological function.
- Temperature and pH influence enzyme activity and play a critical role in maintaining homeostasis.
Consequences of Enzyme Dysfunction
- Enzyme dysfunction due to extreme temperature or pH levels can lead to a range of consequences, including changes in physiological processes.
- Extreme pH levels can affect enzyme function, leading to decreased or lost activity.
Role of Enzymes in Homeostasis and Digestion
- Enzymes play a critical role in maintaining homeostasis by regulating various physiological processes.
- Enzymes are involved in the digestive system, with specific enzymes such as pepsin in the stomach and pancreatic enzymes in the small intestine having optimal pH ranges.
Optimal pH Ranges for Specific Enzymes
- Pepsin, an enzyme in the stomach, has an optimal pH range of 1.5-2.5.
- Pancreatic enzymes in the small intestine have an optimal pH range of 7.5-8.5.
