Where are enzymes active in the body at pH 4 and 5?
Enzymes are active in the stomach, which has an acidic pH between 1.5 and 3.5. At this pH, pepsin is an enzyme that digests proteins. Enzymes in the body typically have optimal pH ranges where they are most active.
Does pepsin affect pH?
Pepsin doesn't affect the pH but it is active in an acidic environment.
Lipase optimum pH?
The optimum pH for lipase activity varies depending on the source of the enzyme. Typically, lipases from human pancreatic juice have an optimum pH of around 8, while microbial lipases from organisms like bacteria or fungi may have different optima ranging from acidic to alkaline conditions. It is important to consider the specific source of the lipase when determining the optimal pH for its activity.
What is active alkalinity?
Active alkalinity refers to the amount of alkalinity that is available in water to resist changes in pH. It is a measure of the water's buffering capacity against acidic substances that can change the pH level. Active alkalinity is important for maintaining stable pH levels in aquatic environments, such as aquariums or natural bodies of water.
What effect do temperature and pH have on enzyme controlled reactions?
enzyme require an optimum temperature and ph level to be active. temperature at which most enzymes are active is around 35-40 degree celcius. above this temperature the enzyme loses it globular structure and thus the substrate will not be able to bind with it. some enzymes are active in alkali ph while others are active in acidic temperature. but most of the enzymes are active in neutral ph and this helps to maintain its globular structure.
What type of bacteria is most likely to go through fermentation?
Assume you are growing bacteria on a lipid medium that started at pH 7. The action of bacterial lipases should cause the pH of the medium to increase or decrease? Why?

Can the active site of an enzyme be damaged at very high pH levels?
The active site of an enzyme can very much be influenced and damaged by a very high pH level. An enzyme is a protein, and because of that it is very sensitive to pH levels. High pH can denature a protein, and thus "damage" the active site.
Does pepsin affect pH?
Pepsin doesn't affect the pH but it is active in an acidic environment.
Lipase optimum pH?

What digests triglycerides?
Lipases

An enzyme that works best in an acidic environment would function best at a pH of what?
An enzyme that works best in an acidic environment would function best at a pH below 7, typically around pH 4 to 6. At this pH range, the enzyme's active site is more stable and optimal for catalyzing reactions.
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 effect do temperature and pH have on enzyme controlled reactions?
enzyme require an optimum temperature and ph level to be active. temperature at which most enzymes are active is around 35-40 degree celcius. above this temperature the enzyme loses it globular structure and thus the substrate will not be able to bind with it. some enzymes are active in alkali ph while others are active in acidic temperature. but most of the enzymes are active in neutral ph and this helps to maintain its globular structure.
Changing the pH in an enzyme will?
Changing the pH in the environment that an enzyme works in can change how active it will be. Most will be active in a narrow range. Pepsin, a stomach enzyme, will only work at very acid pHs and will become inactive at higher pH than 2.
Is pH 9 more acidic than pH 4?
No, pH 9 is actually more basic (alkaline) than pH 4. The pH scale is logarithmic, so each unit is 10 times more acidic or basic than the unit next to it. pH 4 is more acidic than pH 9.
