Difficulty: EasyHealth, Nutrition, and Disease

Match each essential vitamin on the left with its primary physiological function in the human body on the right.

  • Vitamin CFacilitates collagen synthesis and connective tissue repair
  • Vitamin DPromotes calcium absorption in the intestines to support bone health
  • Vitamin ARequired for retinal photopigment formation to support healthy vision
  • Vitamin KEssential for the synthesis of prothrombin and blood clotting factors

Answer

Vitamin C matches collagen synthesis and tissue repair; Vitamin D matches calcium absorption for bone health; Vitamin A matches retinal photopigment formation for vision; and Vitamin K matches prothrombin synthesis for blood clotting.
Each nutrient is accurately paired with its primary biochemical role: Vitamin C enables collagen synthesis, Vitamin D stimulates calcium absorption in the gut for bones, Vitamin A forms the retinal pigments necessary for vision, and Vitamin K synthesizes clotting proteins in the liver.

Step-by-Step Solution

1
Review the primary biological function associated with each vitamin.
Vitamin C produces collagen, Vitamin D regulates calcium absorption, Vitamin A forms visual pigments, and Vitamin K enables blood clotting.
Vitamins are organic micronutrients that perform distinct, non-interchangeable physiological roles in human metabolism and cellular maintenance.
2
Align each vitamin with its corresponding physiological description.
All four pairs are matched to their distinct target physiological processes.
Connecting specific micronutrients to their organ-level roles reinforces foundational nutritional concepts.
