Mama L [17]

By predicting how the sodium-potassium pump becomes integrated into outer cell membrane. The prediction that is false is the mRNA coding into sodium pump is translated into the pump on two ribosomes.

<h3>What is sodium-potassium pump?</h3>

The sodium-potassium pump is an enzyme (an electrogenic transmembrane ATPase) present in the membrane of all animal cells. It is also known as sodium-potassium adenosine triphosphatase, Na+/K+-ATPase, or sodium-potassium ATPase. It serves a number of purposes in cell physiology.

The enzyme Na+/K+-ATPase is activated (i.e. it uses energy from ATP). Three sodium ions are exported and two potassium ions are imported for each ATP molecule used by the pump. As a result, each pump cycle results in the net export of one positive charge.

There are four distinct sodium pump isoforms or subtypes in mammals. Each has distinct qualities and patterns of tissue expression. The P-type ATPase family includes this enzyme.

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.
