Actually the pH of the stomach very acid relative to pH 7 (between pH 1-4). An acidic stomach is optimal for the breaking of hydrogen bonds that makes up the complex compounds in the food we ingest, like proteins. The acidity of the stomach is generated by the excretion of hydrochloric acid (HCl) which combines with pepsinogen to create pepsin into the stomach, which is a strong acid.
What else can I help you with?
Which organ secrets enzymes that are active at a low pH?
The stomach secretes protease enzymes that work best at a pH of around 2.
What PH would work for enzymes produced in the stomach?
It's about 7.5, which means that it is slightly basic. The stomach is acidic, so not only does the basic pH of the small intestine allow the enzymes to function, but it also counteracts with the acidity of the stomach.
At what pH do enzymes work best?
Enzymes work best at a pH that is specific to each enzyme, known as its optimal pH. This optimal pH is typically around neutral, or pH 7, for many enzymes found in the human body. However, some enzymes may work best in acidic or basic conditions depending on their specific function.
When do enzymes work best in biological processes?
Enzymes work best in biological processes when they are at their optimal temperature and pH levels.
Can enzymes function at any pH?
No. They function best at the pH corresponding to their usual/intended environment. For example, pepsin, present in the stomach, which is highly acidic, functions best at acidic pH, while trypsin, secreted into the duodenum together with basic bicarbonate, functions best at moderately basic pH. This is true also within subcellular compartments: the optimal pH of lysosomal enzymes is acidic, matching the acidic proteolytic environment inside the lysosome. That said, most enzymes present in the cytosol (~neutral) and blood (~neutral) function best around neutral pH.
Can enzymes work over a broad range of PH levels?
Enzymes have an optimal pH at which they work most efficiently, but some enzymes can function over a range of pH levels beyond their optimal pH. However, extreme pH levels can denature enzymes, leading to loss of their function.
What would the reaction be in the enzymes if the PH of the stomach was doubled?
The enzymes would become denatured because the PH would be too acid/alkaline (depending which way you double) for them to work properly. Denatured basically means that they would be worn down by the acid, and become mishapen.
All enzymes act best at a pH close neutral?
This is not true. Different enzymes thrive in completely different pH conditions. Consider the protease pepsin, which works in the stomach. It breaks down proteins in acidities as low as pH 2. In the duodenum, lipase works best in slightly alkaline conditions.
Do all enzymes work best at neutral pH?
No, the optimum pH for an enzyme depends on the environment in which it normally works. Your stomach is an acidic environment which contains an enzyme called pepsin. This not only works better in acid environments but actually denatures (that is, totally stops working) if the pH rises above 5.0.
Does digestive enzymes will still function in the small intestin?
The small intestine is the site of work of some digestive enzymes that are secreted there. It is not an ideal site for the continued work of enzymes from the stomach, as the pH is not hospitable for the work of those gastric enzymes.
What is the acid secreated by the stomach?
Hydochloric acid is produced in the stomach to a) kill pathogens in our food b) gives optimum pH for enzymes to work in
How would adding baking soda to the contents of the stomach affect the activity of the enzymes?
Adding baking soda to the contents of the stomach would increase the pH, making it more basic. This change in pH would likely affect the activity of stomach enzymes, which function optimally at an acidic pH. Consequently, the enzymes may not work as effectively, potentially leading to decreased digestion of food.
