In humans, the maintenance of a balanced ph is achieved through a compound called a(n) a. acid b. alkali c. buffer d. electrolyte

Most organisms, including humans, need to maintain a certain pH within a fairly, narrow range in order to sustain life. This is achieved through a compound called buffer that can resist changes in pH, which is key to maintaining stable hydrogen ions. For instance, human blood needs to keep its pH at around 7.4 so human can survive.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
