Free Carbohydrates MCQs with Answers

• A. All of the above statements are true
• B. The hydrolysis of maltose yields glucose and fructose
• C. The hydrolysis of sucrose yields only glucose
• D. The hydrolysis of lactose yields glucose and galactose

Explanation: Lactose is a disaccharide of glucose and galactose, so hydrolysis releases these two monosaccharides.

• A. Cortisone
• B. Insulin

• D. Epinephrine

• A. Pentoses
• B. Disaccharides
• C. Hexoses
• D. Polysaccharides

• A. Phosphoglutamase
• B. Branching enzyme
• C. Debranching enzyme

Explanation: Muscle lacks glucose-6-phosphatase, the enzyme needed to convert glucose-6-phosphate into free glucose for release into blood.

• A. Skeletal muscle
• B. Kidney
• C. Liver
• D. Cardiac muscle

Explanation: Skeletal muscle contains the greatest total amount of glycogen because total muscle mass is much larger than liver mass.

• A. Glycogen
• B. Ribosome
• C. Golgi body
• D. Endoplasmic reticulum

• A. Energy

• A. Proteins
• B. Carbohydrates
• C. Fat
