TOPIC 1: NUTRITION FUNDAMENTALS
7 Questions • 12.3% of Exam • Explores basic concepts and definitions related to nutrition and dietary science.
QUESTION 1
True or False: Nutrition is the science that links foods to health and disease.
Correct Answer: True.
Rationale: Nutrition is a field of study that investigates the relationship between dietary components and their impact on
human health and disease, making it a fundamental connection. By analyzing the effects of various foods and nutrients on
the body, nutrition helps identify the causes and prevention of health conditions, thus linking foods to health and disease.
QUESTION 2
Which type of molecule is defined as a substance that does not contain carbon?
Correct Answer: Inorganic.
Rationale: The term "inorganic" refers to chemical compounds that do not contain carbon-hydrogen bonds, which is a key
characteristic of organic molecules. Inorganic molecules can be composed of various elements, such as oxygen, nitrogen,
and metals, making "inorganic" the correct classification for substances that do not contain carbon.
QUESTION 3
Organic
Correct Answer: A compound that contains carbon and hydrogen.
Rationale: The term "organic" in chemistry refers to compounds that contain carbon and hydrogen, as well as possibly other
elements, due to the original definition given by Antoine Lavoisier, who defined organic compounds as those derived from
living organisms. Over time, this definition was expanded to include synthetic compounds that still contain carbon and
hydrogen, but the core concept remains the same, focusing on the presence of these elements.
