ATI NUTRITION YEAR 2025 REVISED EXAM QUESTIONS AND
ANSWERS GRADED A+ MUST PASS
What is the average minimum amount of carbohydrates needed to fuel the brain? - 130 g/day
Give examples of monosaccharides - Simple carbohydrates.
Glucose and fructose
Give examples of disaccharides - Simple carbohydrates
Sucrose and lactose
Give examples of polysaccharides - Complex carbohydrates
Starch, fiber, glycogen
Why is fiber important for proper bowel elimination? - Adds bulk to feces and stimulates peristalsis to
ease eliminating,
What are Complete proteins? - generally from animal sources, contain all of the essential amino acids
(there are nine essential amino acids).
What are Incomplete proteins? - generally from plants (grains, nuts, legumes, vegetables, fruits), do not
contain all of the essential amino acids
What are Complementary proteins? - food sources that, when eaten together, provide all the essential
amino acids
Proteins have many metabolic functions. List them. - tissue-building and maintenance, balance of
nitrogen
and water, backup energy, support of metabolic processes [nitrogen balance, transportation of
nutrients, other vital substances], support of the immune system
, Undernutrition can lead to protein malnourishment which can lead to what? - kwashiorkor or
marasmus.
Protein provides blank cal/g of energy. - Protein provides 4 cal/g of energy.
Fat is a concentrated form of energy secondary to what? - carbohydrates
Why is fat important? - hormone production,
structural material for cell walls, protective padding for vital organs, insulation to maintain body
temperature, covering for nerve fibers, aid in the absorption of fat-soluble vitamins
What are the different categories of fats? - triglycerides, phospholipids, sterols, saturated fats,
unsaturated fats, polyunsaturated fats, and essential fatty acids
What are triglycerides? - The primary form of fat in food. They combine
with glycerol to supply energy to the body, allow fat-soluble vitamin transport, and form
adipose tissue that protects the body
What are phospholipids? - derived from triglycerides. They are important to cell membrane structure
What is cholesterol necessary for?
What happens if it's consumed in excess? - belongs to the chemical substance group called sterols. It is
necessary for cell
membrane stability and the production of certain hormones and bile salts for digestion.
Ifconsumed in excess, it can build up causing congestion and
increasing the risk for cardiovascular disease.
Essential fatty
