What else can I help you with?
Did pepsin act in absence of HCL?
Pepsin is inactive in the absence of HCl because the acidic environment is necessary to convert pepsinogen into its active form, pepsin. HCl is needed to denature proteins and activate pepsin through a process called autocatalysis.
What is the pH of pepsin?
The pH of pepsin is around 1.5 to 2.5. Pepsin works optimally at this acidic pH environment in the stomach, breaking down proteins into 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.
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.
What is the pH of Pepsin in NaOH?
The pH of pepsin in NaOH would depend on the concentration of NaOH added. Pepsin is an enzyme that functions best at acidic pH levels, around pH 2.0. Adding NaOH, a base, would increase the pH, potentially inactivating the pepsin enzyme as it moves away from its optimal pH range for activity.
Where in the body is pepsin produced?
it is found in the stomach of diffrent animals
When was the discovery of pepsin?
Pepsin was discovered in 1836 by the German physiologist Theodor Schwann. He identified it as a digestive enzyme present in the gastric juice of animals, playing a crucial role in breaking down proteins in the stomach. Pepsin's discovery contributed significantly to the understanding of digestive processes.
What food does pepsin begin to breakdown?
Pepsin begins the digetion of Protein. Pepsin is found in the stomach.
Which enzyme works best in alkaline conditions?
Pepsin in the stomach
Where is pepsin produced What is the effect of pepsin on protein?
Pepsin is produced in the stomach. Pepsin is an enzyme that digests (hydrolyses) proteins into smaller polypeptide molecules.
Is pepsin a protein?
Yes, pepsin is a protein.
Is pepsin a carbohydrate?
No, pepsin is a protein digestive enzyme.
In an experiment of Pepsin and BAPNA is pepsin the substrate?
No, pepsin is not the substrate in the experiment with BAPNA. BAPNA is the synthetic substrate used in this experiment to test the activity of the enzyme pepsin by measuring the rate of substrate cleavage. Pepsin acts on BAPNA as the enzyme, not the substrate.
What enzyme contained in gastric juice?
Protease (pepsin) plus hydrochloric acid
What are the differences between pepsin and pepsinogen?
pepsinogen makes pepsin
Which is not found in the mouth pepsin or ptyalin?
Pepsin is not found in mouth!
Is pepsin present in the stomach?
Yes, pepsin is present in the stomach.
