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.
Why is an acidic environment in the stomach beneficial?
In order for the body to be able to limit digestive proteins' functionality to the stomach, digestive proteins are made so that they can only function in extremely acidic environments. Stomach acidity is the body's way of satisfying this requirement.
What happens to solid egg white when pepsin and NaOH added?
Hey, I'm still a student, so I cannot guarantee that my answer is entirely correct, however, this is what my answer was on a similar question in a matsec paper: > Since pepsin is an enzyme, which works best in acidic environment, such as the one provided i the stomach, no change/ reaction would be observed, because NaOH is an alkaline solution. Therefore, pepsin would not be able to work in an environment with such great pH difference to its optimum. I hope that helped somehow although my answer is probably very late :P Good luck, Angelina
What happens if pepsin is added to NaOH?
If pepsin, an enzyme that breaks down proteins, is added to sodium hydroxide (NaOH), a strong base, the high pH of the NaOH will denature and inactivate the pepsin enzyme. Denaturation is the process where the protein loses its shape and function due to changes in pH, temperature, or other conditions. This would prevent pepsin from being able to digest proteins in the presence of NaOH.
Does V. cholerae die in acid?
Because V. cholerae is sensitive to acid, most cholera-causing bacteria die in the acidic environment of the stomach
What will most likely happen to an enzyme if it is placed in an environment that is too acidic or too basic?
If an enzyme is placed in an environment that is too acidic or too basic, its structure can be denatured, which means its active site will change shape and it will no longer be able to catalyze reactions effectively. This will decrease or even stop its enzymatic activity.
Can sperm swim in an alkaline environment?
Sperm can swim in any environment as long as there mets are required. they only last 4-7 days after ejaculation.
How would the digestion of food be affected if your stomach did not produce hydrochloric acid?
A person's inability to produce hydrochloric acid in the stomach is called achlorhydria. This condition affects the enzyme pepsin, which helps to break down proteins. Pepsin requires a low pH to be activated.
Can recessive allele able to persist if the environment does not favor it?
The recessive allele can only persist in a favorable environment. The proper environment is for two recessive alleles to exist together. Then they would function properly as if the two were a dominant allele.
How does acid rain effect protein shape?
The pH of the environment will change (it'll become more acidic) So the protein won't be able to interact the same therefore the shape will be changed
Is brown sugar acidic?
no! or y else would we be able to eat it????? BBQ sauce usually contains tomato in it which is acidic.
What is acidic salt?
if the salt contains a ionize able hydrogen atom the this salt will b termed as an acidic salt..... as acid contains ionize able hydrogen atoms.... examples are.. NAHSO4
