Final answer:
Fat is important as a bodily energy source because it serves as a major energy store for the body, with about 9 calories per gram compared to 4 calories per gram for carbohydrates and protein. The correct option is 4) it is the body's primary source of energy
Step-by-step explanation:
Fats, also known as lipids, play essential roles in your body. The body can make most of the fats it needs from other nutrients, so you don't have to have much fat in your diet. All cells need fat for building cell membranes.
Fats also are found in high concentrations in brain and nerve cells. Certain vitamins (A, D, E, and K) are fat-soluble, which means that your body stores excess amounts of these vitamins in your body fat. Therefore, these vitamins are more abundant in foods that contain fats.
Fats are the major energy store for the body. You get more energy from a gram of fat than from a gram of carbohydrates. Fat has about 9 calories per gram, while carbohydrates and protein have about 4 calories per gram. However, if you store too much fat in your body, it can have a negative effect on your body. You gain weight, and your heart, muscles, and joints must work harder to move the extra weight. The correct option is 4) it is the body's primary source of energy
