Like most proteins, they are synthesized by the ribosomes in the cell. They react with a specific substrate in order to increase the rate of a chemical reaction within the cell. Without enzymes, reactions would be significantly slower and we would not be able to do the most basic functions, such as breathing or digesting food. Amylase is an type of enzyme.

Anion conductance of frog muscle membranes:Once the product is released from the active site, the enzyme returns to its original shape (Raven ). The three factors that can affect the activity of an enzyme include temperature, pH, and concentration.
The temperature effects enzyme activity. As the temperature increases, enzyme stability decreases. Chronic toxicity, the development of adverse effects as a result of long term exposure to a contaminant or other stressor, is an important aspect of aquatic toxicology.
Adverse effects associated with chronic toxicity can be directly lethal but are more commonly sublethal, including changes in growth, reproduction, or behavior. The environmental impact of mining includes erosion in the environment, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, and surface water by chemicals from mining processes.
Besides creating environmental damage, the contamination resulting from leakage of chemicals also affects the health of the local population.
percent of NH 3 is very dependent on pH You will note that NH 3 is much more dependent on pH than temperature. Within the pH range shown, an increase of one pH unit will increase the NH 3 concentration about fold.. The USEPA publishes water quality criteria for aquatic organisms.
