What are the general functions of a mitochondria

Other than being "the powerhouse of a cell", a mitochondria is responsible for ATP synthesis and cellular respiration, which occurs in the mitochondrial matrix. Various ATP molecules would be used in phosphoryllation which catalyzes enzyme and cell activities. In our  cells, it has an even bigger effect, through chemiosmosis or also known as oxidative phophoryllation, where various ATPs are formed after glycolysis

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
