1Which organ produces salivary amylase, and what is its primary digestive function in carbohydrate breakdown?
A.Pancreas; hydrolysing disaccharides into glucose monomers in the stomach
B.Salivary glands; hydrolysing starch polysaccharides into maltose in the mouth
C.Small intestine; emulsifying dietary lipids into micellar units
D.Gallbladder; activating pepsinogen into pepsin for protein hydrolysis
Explanation: Salivary amylase is synthesized and secreted by the salivary glands into the oral cavity. Its primary biochemical function is to initiate the hydrolysis of alpha-1,4-glycosidic bonds in complex starch polysaccharides, breaking them down into shorter dextrins and the disaccharide maltose.
2How does hydrochloric acid (HCl) in the gastric juice facilitate protein digestion in the human stomach?
A.It hydrolyses peptide bonds directly without requiring enzymatic catalysis
B.It denatures tertiary protein structures and activates pepsinogen into active pepsin
C.It emulsifies dietary proteins into water-soluble chylomicrons
D.It neutralises acidic chyme entering the duodenum from the pyloric sphincter
Explanation: Gastric hydrochloric acid creates an acidic pH (approx. 1.5–2.0) that uncoils and denatures complex tertiary/secondary protein structures, exposing peptide bonds. Crucially, acid cleavage converts the inactive zymogen pepsinogen into the active proteolytic enzyme pepsin.
3What is the critical role of bile salts in the digestion and absorption of dietary lipids?
A.Hydrolysing triglyceride ester bonds into glycerol and free fatty acids
B.Emulsifying large fat globules into microscopic micelles to increase surface area for pancreatic lipase
C.Transporting absorbed triglycerides directly through the hepatic portal vein to the liver
D.Synthesising lipoprotein lipase to degrade chylomicrons in peripheral capillary beds
Explanation: Bile salts act as biological detergents possessing amphiphilic properties. They emulsify large insoluble lipid droplets into fine microscopic micelles, dramatically increasing the surface area accessible to water-soluble pancreatic lipase for efficient enzymatic cleavage.
4How do saturated fatty acids differ structurally and physically from monounsaturated fatty acids?
A.Saturated fatty acids contain double bonds between carbon atoms and remain liquid at room temperature
B.Saturated fatty acids lack double carbon-carbon bonds, maximizing hydrogen bonding and raising melting point
C.Monounsaturated fatty acids contain three or more double bonds and are solid at room temperature
D.Monounsaturated fatty acids are fully saturated with hydrogen atoms along their hydrocarbon chain
Explanation: Saturated fatty acids possess no double bonds ($C=C$) along their hydrocarbon chains, meaning every carbon atom is fully saturated with hydrogen atoms. This straight linear conformation allows tight molecular packing, resulting in higher melting points and solid states at room temperature.
5Why are Alpha-Linolenic Acid (ALA) and Linoleic Acid (LA) classified as essential fatty acids in human nutrition?
A.The human body can synthesise them from dietary cholesterol in the liver
B.Humans lack desaturase enzymes capable of introducing double bonds beyond the carbon-9 position from the carboxyl terminus
C.They provide 17 kJ of metabolisable energy per gram compared to 37 kJ for non-essential fats
D.They are required solely for the renal excretion of water-soluble vitamins
Explanation: Humans lack specific delta-12 and delta-15 desaturase enzymes required to insert double bonds at the omega-3 and omega-6 positions (beyond carbon-9). Consequently, Alpha-Linolenic Acid (omega-3) and Linoleic Acid (omega-6) cannot be synthesized de novo and must be obtained from dietary sources.
6What does a high Glycemic Index (GI) rating indicate about a carbohydrate-containing food?
A.It is digested and absorbed slowly, producing a gradual, sustained rise in blood glucose concentration
B.It is rapidly digested and absorbed, causing a sharp surge in blood glucose and pancreatic insulin release
C.It contains high concentrations of resistant starch that bypasses small intestinal absorption
D.It provides zero metabolisable energy to human physiological systems
Explanation: The Glycemic Index (GI) ranks foods based on their immediate effect on blood glucose levels. High-GI foods (GI $\ge 70$) undergo rapid enzymatic breakdown and intestinal absorption, producing a sharp rise in blood glucose and a pronounced spike in pancreatic insulin secretion.
7What is the primary physiological benefit of soluble dietary fibre in the human gastrointestinal tract?
A.It accelerates gastric emptying and reduces intestinal transit time to zero
B.It dissolves in water to form a viscous gel that slows nutrient absorption and is fermented by gut bacteria into beneficial short-chain fatty acids
C.It irreversibly binds fat-soluble vitamins and prevents their biological utilization
D.It directly hydrolyses complex dietary proteins into free amino acids in the colon
Explanation: Soluble dietary fibre (such as pectin, gums, and beta-glucan) dissolves in intestinal fluid to form a viscous gel network. This gel delays gastric emptying, attenuates postprandial blood glucose spikes, binds bile acids to lower plasma cholesterol, and undergoes colonic bacterial fermentation into short-chain fatty acids (acetate, propionate, butyrate).
8What specific biochemical reaction requires Ascorbic Acid (Vitamin C) during collagen biosynthesis?
A.Phosphorylation of glucose to glucose-6-phosphate
B.Hydroxylation of proline and lysine residues in procollagen polypeptide chains
C.Decarboxylation of pyruvate to acetyl-CoA
D.Deamination of essential amino acids in hepatic tissue
Explanation: Ascorbic acid (Vitamin C) acts as an essential electron donor/reducing cofactor for prolyl hydroxylase and lysyl hydroxylase enzymes. These enzymes hydroxylate specific proline and lysine amino acid residues in procollagen, enabling triple-helix stabilization of mature collagen tissue.
9Which B-group vitamin serves as the precursor for Flavin Adenine Dinucleotide (FAD), a crucial electron carrier in the Krebs cycle?
A.Thiamine (Vitamin B1)
B.Riboflavin (Vitamin B2)
C.Niacin (Vitamin B3)
D.Pyridoxine (Vitamin B6)
Explanation: Riboflavin (Vitamin B2) is the essential structural precursor for the coenzymes Flavin Mononucleotide (FMN) and Flavin Adenine Dinucleotide (FAD). FAD serves as a key electron acceptor in oxidation-reduction reactions, including the succinate dehydrogenase step of the Krebs cycle and mitochondrial electron transport.
10How do Folate (Vitamin B9) and Vitamin B12 (Cobalamin) metabolically interact, and what pathology arises from a functional B12 deficiency?
A.Vitamin B12 inactivates folate; deficiency leads to iron-overload hemochromatosis
B.Vitamin B12 remethylates homocysteine to methionine by transferring a methyl group from 5-methyl-THF; B12 deficiency traps folate and causes megaloblastic anaemia
C.Folate absorbs B12 in the stomach; deficiency causes scurvy and osteomalacia
D.They act independently in bone calcification; deficiency leads to rickets
Explanation: Vitamin B12 is a required cofactor for methionine synthase, transferring a methyl group from 5-methyltetrahydrofolate (5-methyl-THF) to homocysteine to generate methionine and free THF. B12 deficiency traps folate in its 5-methyl-THF form ('methyl-folate trap'), impairing purine/pyrimidine synthesis and causing megaloblastic anaemia alongside neurological demyelination.
