D) 35 to 45 percent of total calories
Answer: A
,
Explanation: The recommended daily intake of lipids is 20 to 35 percent of
total calories. Lipids are essential for cell membranes and hormone
production. Saturated fats should be limited.
Question 5
Carbohydrates are classified as:
A) Simple and complex
B) Simple only
C) Complex only
D) Soluble and insoluble
Answer: A
Explanation: Carbohydrates are classified as simple and complex. Simple
carbohydrates include sugars. Complex carbohydrates include starches and
fiber. Complex carbohydrates are preferred.

A) Monosaccharide
B) Disaccharide
C) Polysaccharide
D) Oligosaccharide
Answer: A
Explanation: Glucose is a monosaccharide. It is the most important sugar in
metabolism. It is used by cells for energy production.
Question 7
Sucrose is a:
A) Disaccharide
B) Monosaccharide
C) Polysaccharide
D) Oligosaccharide
Answer: A
,
Explanation: Sucrose is a disaccharide composed of glucose and fructose. It
is common table sugar. It is broken down into glucose and fructose during
digestion.
Question 8
Starch is a:
A) Polysaccharide
B) Monosaccharide
C) Disaccharide
D) Oligosaccharide
Answer: A
Explanation: Starch is a polysaccharide composed of glucose units. It is the
primary energy storage molecule in plants. It is broken down into glucose
during digestion.
