Question

triglycerides are the bodys 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.

• 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.
• fat - soluble vitamins are dissolved by triglycerides.

Explanation:

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

Answer:

B. One gram of carbohydrate provides less than half the amount of energy in one gram of fat
C. Fats provide energy for the body during rest
D. Fat - soluble vitamins are dissolved by triglycerides
