Effecting the Reaction Rate in Enzymes in Plants and Animals Problem- How do variables temperature and surface area affect the rate of reaction occurring in the enzyme? Information- Enzymes are proteins that act as biological catalysts. They speed up chemical reactions that take place in cells. Enzymes can be found in both liver and potato. They provide a site where reactants can be brought together to react. These reactants are called substrates that fin into the enzyme. The changing of heat‚

In this enzyme lab‚ (insert creative name)‚ the enzyme catalase was observed under varying conditions in order to interpret what prohibits and inhibits the functioning of certain enzymes in chemical reactions. Enzymes aid in chemical reactions by speeding up the time it takes for the reaction to occur‚ without getting “used up” throughout the process. Catalase‚ the specific enzyme used in this lab‚ is a protein abundant in the liver and red blood cells. It enhances the breakdown of hydrogen peroxide

Biomes Comparison Essay Ecologists group earth’s diverse environments into biomes. A biome is a complex of terrestrial communities that develops a large area and is characterized by certain soil climate conditions and particular assemblages of plants and animals. Not all species live in every biome they vary in their adaptations to different conditions. An adaptation is an inherited characteristic that increases an organism’s ability to survive and reproduce. These sorts of variations in plants
