Which enzyme shows the greatest change in its rate of action with the least change in pH?
The enzyme with lowest pH optimum is pepsin. Pepsin works in the stomach in an acidic environment and aids in digestion.
Why microorganisms differ in their pH requirements and explain?
This all goes back to ecology. Some fit into each level of pH. They have found a space (niche) to grow and thrive in.
Why is it so important for cells to buffer solutions against rapid changes in pH?
Basically, it's because the fluids you take in all have different pH's. Naturally, this will change the pH values of your body. This is, obviously, not healthy for your body, so cells buffer the acidic or basic fluids you take in in order to keep you healthy.
Does the pH of the medium change during sterilization?
yes. The PH will changer We have to adjust the pH after sterilization by filtration
A substance with a pH of 11 is what times more what than a substance with a pH of 8?
A pH of 11 is 1000x more alkaline than a pH of 8. The pH scale is a logarithmic scale. This means that in a pH scale, a change of one whole number represents a tenfold change in the pH. So a pH of 8 is 10x more alkaline than a pH of 7.
How can microorganisms change the pH of their own environment?
yes, a simple example is the microrganisums in our mouth, they break down bits of food and produce acid as a by product.
Do microorganisms differ in pH requirement for growth?
No, all microorganisms will not grow optimally at a neutral pH. Several types of fungi, for example, grow better in an acidic environment.
What is the purpose of buffer?
Buffer Resist and Maintains the PH of the solution if there change in the environment of the solution.
Why do microorganisms differ in their pH requirements for growth?
Microorganisms also prefer a certain pH level in the substance or environment in which they grow--that is, they prefer to have particular acidic qualities in their surroundings. Most microorganisms, including most human pathogens, are neutriphils, organisms that prefer a neutral pH level. Some like high pH levels, but most often, if conditions are too acidic, then the organism's enzymes break down.
What is a change in the structure of a protein due to changes in the environment like temperature or pH.?
denature
What is pH in foods?
pH is activity of hydrogen ions in food.if it is low then food will be acidic in nature and shelf life of food increase because microorganisms cant grow in acidic environment it is high then food will be alkaline and shelf life of food will be decreased.
What Four factors which affect the growth of microorganisms?
Four factors which affect the growth of microorganisms are: temperature food source for microorganisms (ie. sugar, protein, fat) the amount of microorganisms introduced to the food source ph of the food source
Which enzyme shows the greatest change in its rate of action with the least change in pH?
The enzyme with lowest pH optimum is pepsin. Pepsin works in the stomach in an acidic environment and aids in digestion.
What is the pH of the environment needed for plants?
pH 7
How does the pH of a substance affect our environment?
The pH of a substance thrown in the environment can lead to a degradation of soils and waters.
What is the pH of saurkraut?
the decrease of the pH in sauerkraut is due to the succession of lactic and acetic acid microorganisms that grow on the brine solution making it acidic.
Does the pH of compost ingredients affect the populations of microorganisms during composting?
yes, it should be 5.5
