An enzyme was isolated from digestive juices taken from the small intestine. an experiment was set up to test the ability of the
Sergio039 [100]
1. Our results showed that test tube B contained end products of protein digestion, meaning that the isolated enzyme has the ability to break down protein. The end products of protein digestion include small polypeptides, dipeptides, and amino acids. In general, test tube B will contain the building blocks of proteins, which are the amino acids.

2. The two test tubes were placed in a hot water bath at 37oC. This is because the enzyme studied is a human enzyme and it works best at the human body temperature, which is approximately 37oC.
Enzymes are biological catalysts, which means that they accelerate chemical reactions. As a result, an enzyme's activity is greatly affected by temperature. Every enzyme, depending on each function and origin, has a specific range of ideal temperature conditions. If the temperature rises above the maximum accepted, then the enzyme denatures and loses its structure.

3. If the enzyme studied was added in a tube containing starch instead of proteins, then nothing would happen. This is because the enzymes are highly specialized and have very specific actions. It has been proved that this enzyme's activity involves the digestion of proteins.
Starch is a polysaccharide produced by plants, this means that starch is a carbohydrate. Given that starch is not a protein, it will not be digested by the enzyme. An enzyme digesting proteins, will not have any effect on carbohydrates.

4. The smaller molecules which are the result of the digestion happening in the digestive system are absorbed by the human body. More specifically, the products of protein digestion are absorbed by the intestine and then transported into the bloodstream. From the blood, they are then absorbed by other tissues.
After they are absorbed, they are used to build muscles or other compounds which can produce energy.

Prokaryotic organisms have a single origin of replication, whereas eukaryotic organisms have many origins where replication occu
vaieri [72.5K]

Answer:

Explained

Explanation:

Prokaryotic cells are generally smaller in size than the eukaryotic cells and thus the DNA in the prokaryotic cells are much smaller than the DNA in the eukaryotic cells therefore, the later organisms have many origins where replication occurs simultaneously. Moreover, Prokaryotic cells lack neucleus and whereas eukaryotic cells have neucleus in them which is bounded by the membrane.

Design an experiment where you would determine how quickly lactaid works to break down milk sugar at different temperatures
choli [55]
1. Gather 11 cups and then fill each cup with 5 ounces of whole milk, next is take the first cup to add a known quantity of lactaid. As a control, take another cup and do not add any lactaid. After 1minute, pour a known quantity of Benedicts into cups of milk. Record the color (blue is the least amount of glucose progressing to green, then yellow, orange, red, and brick red/brown). Take another cup of milk and then add the lactaid and wait 5minutes next is add the Benedicks. Record the color, repeat steps 7-10 adding 5minutes each time until there are no cups left (15 minutes, 20, 25,30,35,40,45).
For the last is Graph the data and form conclusions.
