What are enzymes and their functions?
Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
What two things determine the specific function of an enzyme?
Temperature, pH, concentration of enzymes, concentration of the substrate and concentration of any enzyme inhibitors.
How does the structure of an enzyme help with its function?
How does the structure of an enzyme affect its function? Each enzyme has an area called an active site, this is where a substrate bonds and reacts with the enzyme. The binding of the correct molecule/substrate causes the enzyme to become active and perform its function.
What type of enzymes break down carbohydrates?
Figure 15.16. Digestion of carbohydrates is performed by several enzymes. Starch and glycogen are broken down into glucose by amylase and maltase. Sucrose (table sugar) and lactose (milk sugar) are broken down by sucrase and lactase, respectively.
What happens to enzymes at high temperatures quizlet?
What happens to an enzyme if the temperature get too high? The reaction stops, because the rise in temperatures makes the enzyme’s molecules vibrate more. If the temperature goes above a certain level, this virbration breaks some of the bonds that hold the enzyme in shape.
At what point is an enzyme denatured due to pH quizlet?
If the pH is too high or too low, the enzyme becomes denatured and the reaction rate slows down because the substrate no longer fits the active site.
Which of the following best describes the effect of high temperature on enzymes?
Describe the effects of changes in environmental temperature on enzyme efficiency during catalysis. In lower temperatures, the enzyme will be less active and slow down the reaction. In extremely high temperatures, the enzyme’s hydrogen bonds, ionic bonds, and weak interactions cause the protein molecule to denature.
Which of the following best describes where each enzyme functions?
Which of the following best describes the function of enzymes? Enzymes lower the activation energy level of a chemical reaction, thus making it so the reaction will proceed. lowering the activation energy of a reaction.
