Transcript of Enzyme Presentation
Enzymes- a substance produced by a living organism that acts as a
to bring about a specific biochemical reaction.
"-a substance or layer that underlies something, or on which some process occurs, in particular.
"-a substance that takes part in and undergoes change during a reaction.
"- Something "manufactured" by an enzyme from its substrate.
"-a region on an enzyme that binds to a protein or other substance during a reaction.
"-a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
What They Do
Enzymes function to speed up reactions by lowering the activation energy required to start the reaction.
Can We Stop Them
What if enzymes just kept going and converted every molecule in the world? They would never stop. They would become monsters!" There are many factors that can regulate enzyme activity, including temperature, activators, pH levels, and inhibitors, which we will cover in the next section.
Steps to An Enzymes Process Of Work Part 1
Steps to An Enzymes Process Of Work Part 2
3. A process called catalysis happens. Catalysis is when the substrate is changed. It could be broken down or combined with another molecule to make something new.
4. The enzyme lets go. This is a big deal. When the enzyme lets go, it returns to normal, ready to work on another molecule of substrate. The first molecule is no longer the same. It is now called the product
Why Are They Useful
Enzymes are important because they initiate and regulate biological activity. Enzymes are biological catalysts which means that they speed up chemical reactions inside and outside
An enzyme and a substrate are in the same area. The substrate is the biological molecule that the enzyme will work on.
2. The enzyme grabs on to the substrate at a special area called the active site. Enzymes are very, very specific and don't just grab on to any molecule. The active site is a specially shaped area of the enzyme that fits around the substrate. The active site is like the grasping handle of the robot on the assembly line. It can only pick up one part.
