No, amylase in the mouth does not work best in a very acidic environment. Salivary amylase functions optimally at a neutral to slightly alkaline pH, around 6.7 to 7.0. In highly acidic conditions, such as those found in the stomach, amylase becomes less effective and can be inactivated. Thus, the environment of the mouth is more suitable for its activity compared to that of the stomach.
It works best in an alkaline environment. I can't think of why just yetthough! I'll come back to you on that one, I'll have to do some research! :D
Salivary amylase functions best in a neutral to slightly acidic environment, with an optimal pH range between 6.7 to 7.4. This enzyme works to break down starches into simpler sugars in the mouth before the food reaches the stomach.
Because of enzyme specificity, enzymes require certain temperatures and pH's to work. Now I don't think there is a temperature change, but there is most certainly a pH change as the mouth has a near neutral pH while the stomach has a more acidic pH of about 2-3.
Two examples of enzymes are pepsin and amylase. Pepsin, which is involved in protein digestion, functions optimally in the acidic environment of the stomach, with a pH around 1.5 to 2.5. Amylase, on the other hand, facilitates the breakdown of starches into sugars and works best in a neutral to slightly alkaline environment, with an optimal pH around 6.7 to 7.0, as found in the mouth and small intestine.
Amylase works best in a slightly alkaline environment, with an optimum pH range of 6.7 to 7.0. It can also function in slightly acidic conditions, but its activity decreases as pH deviates from the optimum range.
That they work best in the right pH and temperature they were made to work in. Amylase works best in the mouth's pH of about 7, while pepsin works best at a much lower and acidic pH.
Salivary amylase is an enzyme found in saliva that begins the breakdown of carbohydrates in food by breaking down starch into smaller sugars like maltose. It works best in a slightly acidic environment (pH 6.7-7.4). The enzyme continues to work in the mouth and is eventually inactivated by the acidic environment of the stomach.
Amylase works best at a slightly acidic to neutral pH range of around 6.5 to 7.5. Optimal pH can vary depending on the specific type of amylase and the organism it comes from.
The optimum pH of salivary amylase is 6.8 (slightly acidic).
Pepsin and amylase function optimally at different pH levels due to their distinct roles in digestion and the environments in which they operate. Pepsin, which breaks down proteins, is activated in the highly acidic environment of the stomach (pH 1.5 to 3.5). In contrast, amylase, responsible for carbohydrate digestion, works best in the more neutral pH range of the mouth and small intestine (around pH 6.7 to 7.0). This difference in optimal pH reflects the unique biochemical environments and substrates each enzyme encounters during digestion.
No, pepsin works best in an acidic environment. It is an enzyme produced in the stomach, where the pH is around 1.5-2, which is highly acidic. In this acidic environment, pepsin can efficiently break down proteins into peptides.
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.
