1.What changes occur to chemical bonds during a chemical reaction?

The chemical bonds will be altered or rearranged in chemical reaction. The bond that exist prior of the reaction could be separated or new bond will be formed. The rearrangement of the bond will change the properties of the molecule.


2.How does the change in energy of a chemical reaction predict whether or not the reaction will occur?

Chemical reaction happens when some subtrate molecule/atom collide. To start a chemical reaction there will be a certain amount of energy needed called activation energy. If the energy is not reaching activation energy, the reaction will not occur.


3.Explain the role of enzymes and how they affect the chemical reactions of living things.

Enzyme help chemical reaction by lowering the activation energy of the reaction, make the reaction faster and easier. Living things need to do some chemical reaction to produce and utilize energy. Enzyme could help those reaction, make the organism to produce and utilize energy faster. This will help the living things to fulfill their energy needs.


4.Explain why a key that fits into a lock is a useful model for the function of enzymes.

Key and lock model state that the enzyme is like a key that could only work with a certain type of lock. This because the enzyme has a specific active site in their three dimensional structure that could hold a substrate, and help the chemical reaction. Enzyme only work with substrate that could be hold by their active site, same as "lock" could only work with specific "key".


5.Explain how consuming an acid-neutralizing antacid might affect protein digestion.Apply the concept of activation energy to support your explanation.

Protein digestion happens in the stomach by pepsin enzyme. The ideal condition of the enzyme to work is in acid pH. Using antacid will cause the pH to become neutral. This will alter the enzyme structure, make the enzyme didn't work. If the enzyme didn't work, the activation energy will be much higher and protein digestion will be slower.


6.Predict which temperature ----(20degrees Celsius ,39 degrees celsius, or 50 degree Celsius) --- you would expect a human enzyme to function best.Plan a simple investigation to test your hypothesis.

Human is a warm blooded mammals that keep their body temperature around 37 degrees celsius. The ideal condition of human enzyme activity would be around that temperature. From the option, 39 degrees would be the most appropriate as it was the closest to 37 degrees.

You can investigate this by taking some enzyme and examine their speed in container with different temperature.
