Quizplus · Accepted Answer

Niacin (vitamin B3) and riboflavin (vitamin B2) are directly necessary for the process of cell respiration. They both play a role in the production of ATP, which is the energy currency of the cell. Vitamin C is important for other functions in the body, such as collagen synthesis, while vitamin D primarily plays a role in bone health. Vitamin K is involved in blood clotting and bone health, but not specifically in cell respiration.
