How energy is formed from oscillation of dalbo hydrate fat and protein explain answer
Answers
Answer:
Carbohydrates, proteins, and fats supply 90% of the dry weight of the diet and 100% of its energy. All three provide energy (measured in calories), but the amount of energy in 1 gram (1/28 ounce) differs:
4 calories in a gram of carbohydrate or protein
9 calories in a gram of fat
These nutrients also differ in how quickly they supply energy. Carbohydrates are the quickest, and fats are the slowest.
Carbohydrates, proteins, and fats are digested in the intestine, where they are broken down into their basic units:
Carbohydrates into sugars
Proteins into amino acids
Fats into fatty acids and glycerol
The body uses these basic units to build substances it needs for growth, maintenance, and activity (including other carbohydrates, proteins, and fats).
Carbohydrates
Proteins
