How is stomach acid neutralized in the small intestine
Bingel [31]
"It converts the inactive enzyme pepsinogen into the active enzyme pepsin, which is responsible for digesting proteins in your stomach. HCL also helps digest other foods in your stomach.

True or false? cell death normally does not occur unless there has been an injury to the cell.
Evgen [1.6K]

The statement 'cell death normally does not occur unless there has been an injury to the cell' is false.

A cell can be described as the basic building block of life. All living organisms are known to be made of cells.

There are various reasons that a cell might die. A cell might die when its function is over. A cell might also die for the formation of other structures in the body. For example, the formation of an outer layer of the skin requires dead cells. A cell might kill itself if it has no use or finds that it has been invaded by an antigen.

Hence, the statement that cell death occurs only due to injury is false as cell death can occur due to various other reasons.
