It is sort of like asking "why do I have to drive under a certain speed on a certain road or highway." It is the way it is. The road may not be strong enough for a faster speed or you have to watch for traffic in a small town or those are just the rules.
Cells have a pH they prefer. The proteins inside cells also have preferential pH environments. One type of protein inside a cell that has a preferred pH is an enzyme. Enzymes are proteins that help speed up chemical reactions; they change substrates into products. They have a 3-D structure known as a conformation and are composed of amino acids.
Enzymes also have preferred environments. If an environment is too acidic (low pH) or alkaline (high pH), an enzyme won't function or will become denatured, a state where an enzyme loses its conformation and becomes a rubbish pile of amino acids.
The same with the starch. It breaks down faster at a pH of 5.
What else can I help you with?
How PH effect on amylase breaking down starch to form maltose?
Amylase works most efficiently at a neutral pH (around pH 7). Extreme pH levels (high or low) can denature the enzyme, reducing its activity and ability to break down starch into maltose effectively. Therefore, the pH level can impact the rate and degree of starch breakdown by amylase.
What is the pH for pepsin?
The optimal pH for pepsin, an enzyme found in the stomach that helps in protein digestion, is around 2.0. This low pH is necessary for pepsin to be active and function effectively in breaking down proteins into smaller peptides.
What is the pH optimum of alpha amylase?
The optimum pH is neutral, 7.
What is the optimum PH of lactase catalyzed reaction?
The optimum pH of lactase is pH = 6.5.
What is the optimum pH for stomach protease?
The optimum pH for stomach protease, specifically pepsin, is around 1.5 to 2. It functions best in the highly acidic environment of the stomach, which helps to break down proteins efficiently for digestion.
Can you digest starch?
Pepsin does not digest. It breaks down proteins into amino acids. Pepsin cannot break down starch. This is probably because the pH of starch is higher than the optimum pH of Pepsin.
How PH effect on amylase breaking down starch to form maltose?
Amylase works most efficiently at a neutral pH (around pH 7). Extreme pH levels (high or low) can denature the enzyme, reducing its activity and ability to break down starch into maltose effectively. Therefore, the pH level can impact the rate and degree of starch breakdown by amylase.
What is the optimum pH for catalase activity?
The optimum pH for catalase activity is around pH 7, which is neutral. Catalase works best at this pH level to break down hydrogen peroxide into water and oxygen.
What is the optimum pH of elastases?
The optimum pH for most elastases is around 8.0 to 9.0. Elastases are enzymes that break down elastin in the extracellular matrix of tissues, and they function best within this pH range. Deviation from this pH range can significantly impact the enzyme activity.
What is the optimum pH range for the hydrolysis of carbohydrates in the human mouth?

Does the optimum pH of salivary amylase differ from plant amylase?
Yes, the optimum pH for salivary amylase is around pH 6.7, while the optimum pH for plant amylase can vary depending on the specific enzyme and plant species. Plant amylase enzymes may have an optimum pH range that can span from slightly acidic to neutral conditions.
What is the pH for pepsin?
The optimal pH for pepsin, an enzyme found in the stomach that helps in protein digestion, is around 2.0. This low pH is necessary for pepsin to be active and function effectively in breaking down proteins into smaller peptides.
What is the pH optimum of alpha amylase?
The optimum pH is neutral, 7.
What is the optimum PH of lactase catalyzed reaction?
The optimum pH of lactase is pH = 6.5.
What effect would a higher pH have on the temperatures optimum for invertase?
The temperature optimum can be affected by pH if the pH chosen for a particular experiment deviates from the pH optimum for invertase
How can you determine the optimum pH of an enzyme?
To determine the optimum pH of an enzyme, you can conduct experiments at different pH levels and measure the enzyme activity. The pH at which the enzyme shows the highest activity is considered its optimum pH.
Why does amylase work best at pH around 7?
Amylase, an enzyme that breaks down starch into simpler sugars, works best at a neutral pH around 7 because its active site is most stable at this pH. Enzymes are sensitive to changes in pH, and deviations from the optimal pH can disrupt the enzyme's structure and function. At a pH of 7, amylase can efficiently catalyze the hydrolysis of starch into maltose and glucose.
