Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.

Part B. Use the data collected by industry scientists (in Part A) to complete the following
graphing activity. – This activity involves drawing two graphs.
1. You would like to visualize the effect of lotion type on the total average redness after 30 minutes of sun
exposure. Construct a bar graph to visualize your results. Use appropriate scale, label the axes with
names and units of measurement, and give the graph a "good" title.

Part A. Use your understanding of the scientific process to answer the following questions.
Sun Kissed is a popular sunscreen that has been successfully used to prevent burns for many years.
Recently, industry scientists developed a new chemical that may be more effective at preventing burns.
The sunscreen with the new active ingredient is called Sun X. Industry scientists gathered 100 test
subjects and applied three different lotions to three different square inch patches of skin on each
subject's arm. The three different lotions applied to each test subject were: Sun X, Sun Kissed, and
the lotion alone with no active ingredient. (The same amount of lotion was applied to each area of
skin tested.) After waiting 20 minutes for the lotion to soak into the skin, the test subject's arms were
exposed to direct sunlight. The amount of redness was measured (in units/square inch) every five
minutes for a total of 30 minutes.
Below is the data collected from the experiment:
