Which statement(s) regarding the term "Calorie" (a "large" food energy value, which is C- not the c- calorie that is 1/1000 of a Calorie) is (are) incorrect. *

Check all that are incorrect. [You will need to do some research beyond this video to answer this and some of the other questions.]

1 Calorie is the amount of energy needed to raise 1 kilogram (2.2 pounds) of water 1 degree Celcius.

1 Calorie equals 4,184 Joules

1 /1000 of a Calorie will raise 1 liter of water (1,000 grams) 1 degree Celcius.

1 gram of protein produces about the same amount of energy when digested as 1 gram of carbohydrate.

400 grams of fat produces the same number of Calories of energy as 900 grams of protein when digested.

The same mass of either a fat, a carbohydrate, or a protein will produce the same relative amount of energy when fully digested.

Briefly define: 1) anabolism, 2) catabolism, and 3) metabolism. *

Also, use "anabolic steroids" in a sentence.

How much of the energy from the digestion of food that is consumed goes towards maintaing the body's basic functions: regulating body temperature, breathing, etc. (basal metabolism)? *

90%

70%

35%

20%

10%

Briefly explain whether the energy needed to think of answers to these questions should be included in the basal metabolic energy or should not be because it is above the basal requirement? *

Compare the thinking process to physical exercise.

To maintain a healthy body, every female should consume foods that produce exactly 2,000 calories a day, and every male 2,500 calories a day. *

Briefly explain why you agree or disagree with the statement.
