The correct answer -
D. erythrocyte
Answer:
63-218 grams per day of proteins
56-97 grams per day of lipids
280-400 grams per day of carbohydrates
Explanation:
The Acceptable Macronutrient Distribution Ranges indicate ranges of carbohydrate, fat, and protein combinely will provide 2500 kilocalories per day.
A kilocalorie is the amount of heat energy which is required to raise the temperature of 1 kg of water by 1 degree Celsius.
So, by combining a diet that contains 63-218 grams of protein, 280-400 gram of carbohydrate and 56-97 grams of lipids(fats) will provide enough energy to the body to perform various tasks of the body.
The food reaches the stomach via the esophagus where it undergoes churning; here various digestive juices secreted by the stomach lining mix with the food rendering it to a semi solid mass of soup like consistency known as 'chyme'. The stomach digests nutrients like salt and sugar while other complex food products are digested in the small intestine where the food passes from the stomach.
In the small intestine the food mixes with vital enzymes secreted by the liver and the pancreas; fats and proteins are mainly digested in the small intestine. The inner lining of the small intestine is covered by projections called as villi that absorb the digested nutrients from the food and convey it to the blood stream.
