Pepsin is released by the Chief Cells in the stomach in response to the ingestion of food. It cleaves(breaks up) proteins into smaller groups of amino acids called peptides which can be further broken down by other enzymes later in the GI tract and then absorbed into the body. Specifically it cleaves the bond at the N-terminus of most aromatic amino acids.
What else can I help you with?
Where does pepsin work in the digestive system?
Pepsin works in the stomach in the digestive system.
What substance must be present in the stomach for pepsin to work best?
Pepsin works best in an acidic environment, so the substance that must be present in the stomach for pepsin to work best is hydrochloric acid. This acid helps to activate pepsinogen into its active form, pepsin, which is responsible for breaking down proteins in the stomach.
Where does pepsin work in the body and what is its role in the digestive process?
Pepsin works in the stomach and plays a key role in breaking down proteins into smaller molecules during the digestive process.
Is pepsin a protein?
Yes, pepsin is a protein.
Is pepsin present in the stomach?
Yes, pepsin is present in the stomach.
What organic compound does pepsin work to catalyze?
what organic compound does pepsin catalyze
Where does pepsin work in the digestive system?
Pepsin works in the stomach in the digestive system.
What substance must be present in the stomach for pepsin to work best?
Pepsin works best in an acidic environment, so the substance that must be present in the stomach for pepsin to work best is hydrochloric acid. This acid helps to activate pepsinogen into its active form, pepsin, which is responsible for breaking down proteins in the stomach.
What type of environment does pepsin work best?
pepsin would work best at 98.6 degrees Fahrenheit (37 C) because it is the average normal body temperature.
Why does protein digestion require the presence of both pepsin and HCl?
Protein digestion requires the presence of both pepsin and HCl because pepsin needs an acidic environment to be able to "work" or do its job. Pepsin needs an environment with a pH around 2, which is roughly the pH of HCl. Therefore, HCl aids pepsin in protien digestions by creating an optimal environment for pepsin to work and digest proteins.
Will pepsin work at 10 degrees C?
10o Celsius = 50o Fahrenheit, which may be a little low for the optimum efficiency of the pepsin enzyme.
How do pepsin hydrochloric acid work together to digest food in the stomach?
Contrary to popular belief, the acid is not directly responsible for the digestion of nutrients in the stomach. The hydrochloric acid is there to provide suitable acidic conditions for pepsin to work efficiently. The pepsin breaks down proteins into smaller amino acids.
Can pepsin work under the acidic conditions present in the stomach?
Yes, pepsin can work under acidic conditions in the stomach because it is optimally active at a low pH. The acidic environment in the stomach helps activate pepsinogen, the precursor to pepsin, and maintains the pH range suitable for pepsin to function in breaking down proteins into smaller peptides.
Why is HCl used to start the pepsin reaction?
To denature the protein. Pepsin can work pnly if the secondary structure of the protein is broken up.
What enzyme work on proteins?
There are several types. Protease,tripsin,pepsin aresome
Witch acid is used to digest food in the stomach?
Pepsin, which digests protein in the stomach, requires an acidic environment in order to work properly. Hydrochloric acid is stored in the stomach so that pepsin has a good environment to work in.
What food does pepsin begin to breakdown?
Pepsin begins the digetion of Protein. Pepsin is found in the stomach.
