Question

multiple choice question
one thousand calories is called a calorie (capital c) in dietetics and a ______ in biochemistry.

○ joule
○ dalton
○ liter
○ kilocalorie

Explanation:

To solve this, we analyze each option:

• Joule is a unit of energy, but 1 calorie (small c) is about 4.184 joules, and this isn't the term for 1000 calories in biochemistry.
• Dalton is a unit of mass (for atoms/molecules), irrelevant here.
• Liter is a unit of volume, not energy.
• Kilocalorie: By definition, 1 kilocalorie (kcal) is equal to 1000 calories (small c). In dietetics, a Calorie (capital C) is 1000 small calories, and in biochemistry, this is also called a kilocalorie.

Answer:

D. kilocalorie
