If the Na+ voltage-gated channels in a muscle cell open, the Na (sodium) ions rush inside the muscle cell and makes the cell more positive as Na ions carry positive charge on it. Due to the entry of positively charged ions inside the cell, the cell becomes less negative and more positive. This is called depolarization of cell.
Heat always flows from a WARMER object to a COOLER one.
If not for the repair enzymes, an error in the DNA replication process could possibly cause a fatal error to the cell and the human
<span>There are three primary systems in the body that act as a buffer, in order to help maintain pH stability.
The first is known as the phosphate buffer, which neutralizes excess hydroxide ions as they enter cellular fluid.
The second is called the protein buffer, and maintains acidity in the body. The hemoglobin in blood, which binds to acids in the bloodstream, is one such example of this system.
The third system is called the carbonic acid bicarbonate buffer, which neutralizes the acids generated by various metabolic processes, such as digestion and respiration.</span>
