Answer 2

Hy myra,
pH is a very vast topic..
Definition toh u must be knowing
I'll brief the role of pH in biotechnology,
Well,
pH is one of the most important parameters of cell-culture and fermentation processing in the biotech industry.
The statement says that we do cell cultures to identify various electrolytes, nutrients, minerals, glucose levels, vitamins in blood.
The pH activity of these substances also help in determining the values in cell culture.
Also, each enzyme has certain pH at which it can act. pH also has an important role in enzyme activity. Each enzyme has certain amount of pH at which it will act. Role of enzymes and pH is considered very important in the medical literature.
Besides enzymes, our whole digestive system works on pH mechanism, saliva has acidic pH, which if falls below, 5.5, dental caries will occur. 5.5 is known as the critical pH of saliva in dental biochemistry.
In stomach too, acidic pH is there.
Intestine has an alkaline pH.
In cell injuries, pH of the cell may increase or decrease depending on the type of injury.
Hope it helps.
Thanks.
