Buffer solution is able to retain almost constant pH when small amount of acid/base is added. Quantitative measure of this resistance to pH changes is called buffer capacity.
Buffer capacity can be defined in many ways. You may find it defined as "maximum amount of either strong acid or strong base that can be added before a significant change in the pH will occur". This definition - instead of explaining anything - raises a question "what is a significant change?" - sometimes even change of 1...

In the cell have the chemical components which maintain the pH. So it always in optimum pH. The chemical components of solution is mineral salts in the form of phosphate salt solution.
The phosphate buffer system operates in the internal fluid of all cells. This buffer system consists of dihydrogen phosphate ions (H2PO4-) as hydrogen-ion donor (acid) and hydrogen phosphate ions (HPO42-) as hydrogen-ion acceptor (base). These two ions are in equilibrium with each other as indicated by the chemical...
Enzymes are structured protein compounds which function as a catalyst and is known as bio-catalyst. Enzymes act as catalysts that catalyze chemical reactions that occur in biological systems.
In performing its role as a bio-catalyst in the body, how the enzyme is influenced by several factors, one of which is the degree of acidity or better known as the pH, this is because the enzyme is only willing and able to work at certain pH conditions. A pH conditions where the enzyme can work with the highest...
A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. It has the property that the pH of the solution changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. Many life forms thrive only in a relatively small pH range; an example of a buffer solution is blo...
The central dogma of molecular biology was first articulated by Francis Crick in 1958 and re-stated in a Nature paper published in 1970:
The central dogma of molecular biology deals with the detailed residue-by-residue transfer of sequential information.. It states that information cannot be transferred back from protein to either protein or nucleic acid.
In other words, 'once information gets into protein, it can't flow back to nucleic acid.'
The dogma is a framework for understanding the transfer...

Crawling around me...
Sleepless eyes...
Your hands, they haunt me...
finger tipping down my spine.
Heaven forbid, well aware of your sins.
In the wake I'll be just like the rest.
Tell the sun don't fall, so we'll never forget.
Heaven forbid, well aware of your sins.
In the wake I'll be just like the rest.
Past praying for.
Always kept quiet...
Clenching my teeth.
Find me fighting the floor.
Raise me from my bones once more.
You're way past praying for.
I wouldn't want to wake you from yourself.
...doesn't...
