NUTR 121 UNLV Exam 2 | Actual study
set | Questions and Answers
Two classifications of Carbohydrates - ANSW-Simple & Complex
Simple Carbohydrates - ANSW-Monosaccharides (Glucose, Fructose, Galactose) Disaccharides (Sucrose,
Lactose, Maltose)
Main Monosaccharide found in body? - ANSW-Glucose
What is a complex Carbohydrate? - ANSW-Long chains of glucose molecules (>10) (Polysaccharides)
Three forms of complex Carbohydrate? - ANSW-Fiber, Starch, Glycogen
What is Starch? - ANSW-Storage form of glucose in plants
What is the storage form for animals? - ANSW-Glycogen (Stored in muscles and liver)
Sources of Starch - ANSW-Grains (Wheat, rice, corn, oats, and barley) Legumes (Peas, beans, and lentils)
Tubers (potatoes and yams)
What are the body's preferred fuel sources? - ANSW-Carbohydrates (Brain cells, nerve cells, red blood
cells) and Fats
During high-intense workout, what is the primary fuel source? - ANSW-Carbohydrates
During low-intense workout/ rest, what is the primary fuel source? - ANSW-Fats
What does the body as an alternate source b/c of a lack of Carbohydrates? - ANSW-Ketones
What does an excessive amount of Ketones lead to? - ANSW-Ketoacidosis
Why is Ketoacidosis dangerous? - ANSW-Makes the blood very acidic; damages body tissues
What component of foods do we not absorb/digest? - ANSW-Fiber
Health benefits from fiber? - ANSW-Fiber helps prevent cardiovascular disease, lowers chance for Type 2
diabetes, promotes bowel health, (prevents constipation & diverticulosis), reduce risk of colon cancer,
weight management
What disease is associated with low fiber diet? - ANSW-Diverticulosis
Where is salivary amylase found? - ANSW-Mouth (Begins break down of CH through chemical digestion)
Largest amount of digestion occurs in? - ANSW-Small intestine
What hormones regulate blood glucose levels? - ANSW-Insulin and Glucagon
What does insulin do? - ANSW-Helps glucose get into cells (Occurs when: High blood glucose levels)
What does glucagon do? ( - ANSW-Triggers glycogenolysis (liver converts stored glycogen into glucose),
stimulates gluconeogenesis (break down protein to converts to glucose, or fat) (Occurs when: Low blood
glucose levels)
AMDR for Carbohydrates? - ANSW-45%-65%
What does it mean if a food is enriched with nutrients? - ANSW-Foods that were lost during processing
are added back in
What does fortified mean? - ANSW-Adding a food that wasn't originally there
What are the 3 major classes of lipids found in the body? - ANSW-Triglycerides, Phospholipids, Sterols
What is the structure of a triglyceride? - ANSW-Three fatty acids attached to glycerol molecule
