Question

triglycerides are the body’s most efficient method for storing energy. in fact, a gram of fat supplies more than double the amount of energy a gram of carbohydrate or protein supplies! energy from stored fats is slowly released to cells between meals. fats fuel processes like breathing and long, slow activities like hiking.

in addition to providing energy, triglycerides help dissolve nonpolar vitamins a, d, e, and k. stored body fat also cushions bones and organs, and it provides insulation to retain body heat.

select the true statements.

• fat-soluble vitamins are dissolved by triglycerides.
• fats are less energy-dense than carbohydrates.
• one gram of carbohydrate provides less than half the amount of energy in one gram of fat.
• fats provide energy for the body during rest.

Explanation:

1. For "Fat - soluble vitamins are dissolved by triglycerides": The text says triglycerides help dissolve nonpolar vitamins A, D, E, and K, and these are fat - soluble vitamins. So this statement is true.
2. For "Fats are less energy - dense than carbohydrates": The text states a gram of fat supplies more than double the energy of a gram of carbohydrate, so fats are more energy - dense. This statement is false.
3. For "One gram of carbohydrate provides less than half the amount of energy in one gram of fat": Since a gram of fat has more than double the energy of a gram of carbohydrate, a gram of carbohydrate has less than half the energy of a gram of fat. This statement is true.
4. For "Fats provide energy for the body during rest": The text says energy from stored fats is released between meals and fuels processes like breathing (which occurs during rest). So this statement is true.

Answer:

• Fat - soluble vitamins are dissolved by triglycerides (True)
• Fats are less energy - dense than carbohydrates (False)
• One gram of carbohydrate provides less than half the amount of energy in one gram of fat (True)
• Fats provide energy for the body during rest (True)

The true statements are: "Fat - soluble vitamins are dissolved by triglycerides", "One gram of carbohydrate provides less than half the amount of energy in one gram of fat", "Fats provide energy for the body during rest".
