AIOU Solved Assignment Code 484 Solved Questions & Model Answers

To assist students who wish to understand the conceptual depth required for university examinations, we have transcribed verified model solutions to key assignment questions below:

Assignment No. 1 – Question 1

Question: Explain the physiological functions of proteins and differentiate between Kwashiorkor and Marasmus.

Model Answer:

Proteins serve as structural building blocks for cellular repair, enzyme catalysis, immune antibody synthesis, hemoglobin transport, and fluid equilibrium maintenance. Protein-Energy Malnutrition (PEM) manifests in two distinct pediatric pathologies: 1. Kwashiorkor results primarily from acute protein deficiency despite adequate caloric intake; clinical symptoms include bilateral pitting edema, abdominal distension (pot-belly), enlarged fatty liver, lethargy, and flag-sign depigmentation of hair. 2. Marasmus results from chronic starvation of both protein and overall energy/calories; symptoms include severe muscle wasting, complete loss of subcutaneous fat, an emaciated “old man” facial appearance, and severe growth stunting without edema.

Assignment No. 1 – Question 2

Question: Classify vitamins into fat-soluble and water-soluble categories and outline the clinical symptoms of Vitamin A and D deficiencies.

Model Answer:

Vitamins are classified into: 1. Fat-Soluble Vitamins (A, D, E, K), which require dietary dietary lipids for absorption and are stored in hepatic and adipose tissues. Vitamin A deficiency leads to impaired rhodopsin synthesis causing Nyctalopia (night blindness), Xerophthalmia (corneal dryness), and Bitot’s spots. Vitamin D deficiency impairs calcium homeostasis, causing Rickets (bowed legs and skeletal deformities) in children and Osteomalacia in adults. 2. Water-Soluble Vitamins (Vitamin C and B-Complex), which dissolve in bodily fluids, are excreted via urine, and require daily dietary replenishment.

Assignment No. 1 – Question 3

Question: Describe the dietary guidelines and nutritional modifications required for a pregnant and lactating woman.

Model Answer:

During pregnancy, daily caloric requirements increase by approximately 300-450 kcal during the second and third trimesters to support fetal development and placental growth. Protein intake must increase by 25g daily. Essential micronutrient supplements include: Folic Acid (400-800 mcg daily) to prevent neural tube defects (spina bifida); Elemental Iron (30-60 mg daily) to prevent gestational anemia and support fetal blood volume; Calcium (1000-1200 mg) for fetal skeletal ossification; and Iodine. During lactation, maternal fluid intake must increase significantly alongside an extra 500 kcal to maintain nutritious breast milk synthesis.

Assignment No. 2 – Question 1

Question: What is the Glycemic Index (GI) and how does dietary fiber assist in glycemic regulation and lipid reduction?

Model Answer:

The Glycemic Index (GI) is a numerical ranking (0-100) indicating how rapidly a carbohydrate-containing food elevates blood glucose concentrations compared to pure glucose. High-GI foods (white bread, refined sugar) induce rapid insulin spikes. Soluble dietary fiber (pectin, beta-glucan found in oats and legumes) forms a viscous gel inside the small intestine, physically slowing enzymatic starch breakdown and glucose absorption, preventing postprandial hyperglycemia. Furthermore, soluble fiber binds bile acids, forcing the liver to consume circulating LDL cholesterol to manufacture fresh bile, lowering serum cholesterol.

Assignment No. 2 – Question 2

Question: Explain four industrial and home food preservation methods and their biochemical principles of inhibiting microflora.

Model Answer:

1. Pasteurization / Thermal Processing: Applies controlled heat (e.g., 72°C for 15 seconds) to denature bacterial proteins and inactivate spoilage enzymes without destroying vital nutrients. 2. Low-Temperature Refrigeration / Freezing: Lowers temperature below 4°C (or -18°C), dramatically retarding microbial kinetic reproduction and enzymatic degradation. 3. Dehydration / Drying: Removes unbound free water (lowering water activity Aw below 0.60), creating an environment where bacterial and fungal spores cannot germinate. 4. Chemical Preservation (Salt / Sugar curing): Creates hypertonic osmotic pressure, drawing water out of bacterial cells (plasmolysis) and destroying them.
