Standard 1.3 Explain the role of enzymes as catalysts that lower the activation energy of biochemical reactions. Identify factors, such as pH and temperature, that have an effect on enzymes.
Vocabulary:
Enzyme
Substrate
Active Site
Product
Activation Energy
pH
Acid
Base
Temperature
HINTS:
ENZYMES are proteins that speed-up chemical reactions in organisms
The enzymes react with a substrate to form a product
Enzymes lower the ACTIVATION ENERGY of the chemical reaction. It makes a slow reaction move faster.
The pH Scale
The pH scale goes from 0 to 14 with 7 in the middle.
7 is neutral
below 7 is an acid
above 7 is a base
7 is neutral
below 7 is an acid
above 7 is a base
