Define free energy and describe how it applies to chemical reactions. Explain how an enzyme affects the energy of a reaction, but not the free energy.
Free energy is the available energy in the substance to do the chemical work that’s part of chemical reactions. Enzymes work by decreasing the activation energy. The free energy of the product is the same as it if it was without the enzyme therefore it does not affect the free energy of the reaction.
What happens to an enzyme after it has catalyzed a reaction?
They can refresh, reset, and restart, ready to be used in the next one.
Describe feedback inhibition, competitive inhibition, and noncompetitive inhibition.
Feedback inhibition is when the product in the pathway stops the enzyme/the production of a substance. There are two main ways in which enzymes are inhibited. Either through …show more content…

At what temperature is the rate of reaction the highest? Lowest? Explain.
The temperature at 34 C is the highest rate of reaction. And the lowest is 4 C and 51 C at 1 ml after 30 seconds.
Why might the enzyme activity decrease at very high temperatures?
Reaction rate increases as temperature increases but then declines at a maximum level even with further increased temperature. This might be due to the enzymes being denatured once it reaches a maximum level.
Why might a high fever be dangerous to humans?
High fevers can be very dangerous because once at a certain level, brain enzymes can be denatured and can be life threatening due to damage it can have on your brain.
What is the optimal temperature for enzymes in the human body?
The optimal temperature for enzymes in the human body is said to be around 37 C which agrees with our results.
Part B: The Effect of pH on Enzyme Activity
Graph the volume of oxygen produced against the pH of the solution.
At what pH is the rate of reaction the highest? Lowest?
