TASC Food and Nutrition Level 3 Practice Questions - TASC Food and Nutrition Level 3 (FDN315118) Exam - TASC Food and Nutrition Level 3 Practice Questions - TASC Food and Nutrition Level 3 (FDN315118) Exam

Question 1

Which organ produces salivary amylase, and what is its primary digestive function in carbohydrate breakdown?

Pancreas; hydrolysing disaccharides into glucose monomers in the stomach Salivary glands; hydrolysing starch polysaccharides into maltose in the mouth Small intestine; emulsifying dietary lipids into micellar units Gallbladder; activating pepsinogen into pepsin for protein hydrolysis

Correct Answer:

Salivary glands; hydrolysing starch polysaccharides into maltose in the mouth

Question 2

How does hydrochloric acid (HCl) in the gastric juice facilitate protein digestion in the human stomach?

It hydrolyses peptide bonds directly without requiring enzymatic catalysis It denatures tertiary protein structures and activates pepsinogen into active pepsin It emulsifies dietary proteins into water-soluble chylomicrons It neutralises acidic chyme entering the duodenum from the pyloric sphincter

Correct Answer:

It denatures tertiary protein structures and activates pepsinogen into active pepsin

Question 3

What is the critical role of bile salts in the digestion and absorption of dietary lipids?

Hydrolysing triglyceride ester bonds into glycerol and free fatty acids Emulsifying large fat globules into microscopic micelles to increase surface area for pancreatic lipase Transporting absorbed triglycerides directly through the hepatic portal vein to the liver Synthesising lipoprotein lipase to degrade chylomicrons in peripheral capillary beds

Correct Answer:

Emulsifying large fat globules into microscopic micelles to increase surface area for pancreatic lipase

Question 4

How do saturated fatty acids differ structurally and physically from monounsaturated fatty acids?

Saturated fatty acids contain double bonds between carbon atoms and remain liquid at room temperature Saturated fatty acids lack double carbon-carbon bonds, maximizing hydrogen bonding and raising melting point Monounsaturated fatty acids contain three or more double bonds and are solid at room temperature Monounsaturated fatty acids are fully saturated with hydrogen atoms along their hydrocarbon chain

Correct Answer:

Saturated fatty acids lack double carbon-carbon bonds, maximizing hydrogen bonding and raising melting point

Question 5

Why are Alpha-Linolenic Acid (ALA) and Linoleic Acid (LA) classified as essential fatty acids in human nutrition?

The human body can synthesise them from dietary cholesterol in the liver Humans lack desaturase enzymes capable of introducing double bonds beyond the carbon-9 position from the carboxyl terminus They provide 17 kJ of metabolisable energy per gram compared to 37 kJ for non-essential fats They are required solely for the renal excretion of water-soluble vitamins

Correct Answer:

Humans lack desaturase enzymes capable of introducing double bonds beyond the carbon-9 position from the carboxyl terminus
