Final answer:
In plasma, the four classes of nutrients include carbohydrates, lipids, proteins, and vitamins. These encompass the necessary macronutrients and micronutrients required by the body for various functions, including energy, building, and regulatory processes.
Step-by-step explanation:
The classes of nutrients normally found in plasma include a variety of substances essential for body energy, building materials, and body processes. The plasma, which is the liquid component of blood, contains organic and inorganic nutrients suspended in a fluid that is approximately 90% water.
Carbohydrates, lipids, and proteins are the macronutrients that the body requires in large amounts. In addition, plasma contains vitamins and minerals, which are micronutrients needed in smaller amounts but are essential for various bodily functions. Along with these, plasma also contains electrolytes such as sodium, potassium, and calcium ions; dissolved gases like oxygen and carbon dioxide; and other organic nutrients including glucose and amino acids, all of which contribute to the total volume of plasma.
To answer the student's question, the classes of nutrients found in plasma include: a) Carbohydrates, lipids, proteins, vitamins
