Which of the following statements is/are correct regarding fats? 1. Fats are needed for the formation of cell membrane. 2. Fats help the body to absorb calcium from food. 3. Fats are required to repair damaged tissue. 4. Body cannot release energy in fats as quickly as the energy in carbohydrates. Select the correct answer using the code given below.

Fats are essential components of the cell membrane, primarily in the form of phospholipids and cholesterol, which create semipermeable barriers for cells. Regarding energy, while fats provide more calories per gram than carbohydrates, they are the slowest source of energy to be released and utilized by the body. Carbohydrates are the quickest source of energy because they are smaller molecules that can be broken down and absorbed rapidly. Statement 2 is incorrect because while fats aid in the absorption of fat-soluble vitamins (A, D, E, K), it is Vitamin D that specifically facilitates calcium absorption [1]. Statement 3 is incorrect because the primary role of repairing damaged tissues and building muscle belongs to proteins, not fats. Therefore, only statements 1 and 4 are correct.
