What else can I help you with?
When the enzyme reaction is complete can pepsin be resued?
yes
Is effect of pepsin on proteins a chemical reaction?
Yes, it is. Proteins in the presence of pepsin are converted into peptide chains (polypeptides). The reaction is : Proetins→ (In the presence of pepsin-to be written over the arrow) Polypeptides.
How is rate of pepsin catalyzed reaction affected by using less pepsin?
Well using less pepsin means you have less of the enzyme. Now if you keep the substrate / enzyme ratio constant there won't be anything changing. If you however decrease the pepsin amount, there will be less active sites for the same amount of substrate to bind. ---> slower reaction
What is the rate of the pepsin-catalyzed reaction at pH 8 with the rate of the lipase-catalyzed reaction at pH 8?
The rate of the pepsin-catalyzed reaction at pH 8 is generally low because pepsin is most active in the acidic environment of the stomach, typically around pH 1.5 to 3.5. In contrast, lipase operates optimally at a higher pH, around pH 7 to 8, making it more effective under those conditions. Therefore, at pH 8, the lipase-catalyzed reaction would likely proceed at a significantly higher rate than the pepsin-catalyzed reaction.
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.
Is pepsin and lipase a chemical reaction?
No, pepsin and lipase are enzymes. Enzymes are biological molecules that catalyze chemical reactions in living organisms. Pepsin helps break down proteins into peptides, while lipase aids in the breakdown of fats into fatty acids and glycerol.
What would happen if pepsin was mixed with glucose?
Pepsin is an enzyme that primarily breaks down proteins into smaller peptides in the acidic environment of the stomach. If pepsin were mixed with glucose, there would be no significant reaction, as glucose is a simple sugar and not a protein. Pepsin does not act on carbohydrates, so the glucose would remain unchanged in this mixture. Therefore, the interaction between pepsin and glucose would not produce any meaningful biochemical effect.
What is the rate of reaction of the enzyme pepsin on egg white?
The rate of reaction of the enzyme pepsin on egg white is influenced by several factors, including temperature, pH, and the concentration of substrates. Pepsin is most active in the highly acidic environment of the stomach, typically around pH 1.5 to 2.0, where it effectively breaks down proteins in egg white into smaller peptides. The reaction rate increases with substrate concentration up to a certain point, after which it plateaus as the enzyme becomes saturated. Overall, pepsin is efficient at digesting egg white proteins, demonstrating significant activity under optimal conditions.
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.
