Vitamins and Deficiency Diseases GK Quiz Level 2: Nutrition and Digestion
This Level 2 GK quiz develops your ability to link nutrients, enzymes and organs to their exact roles. It covers vitamin sources and vitamin loss in food, mineral and protein deficiencies, and how the alimentary canal digests and absorbs food. Aptitude360 includes an explanation for every question, across statement, match and odd-one-out formats.
Areas tested in the Level 2 vitamins set
- Vitamins: sources of Vitamins A, C and D, and why washing vegetables after cutting or overcooking them loses nutrients
- Deficiencies: symptoms of scurvy, rickets, beriberi and night blindness, effects of calcium, iron and iodine shortage, and effects of long-term lack of protein
- Digestive juices: where salivary amylase, pepsin, bile and trypsin are produced, and the roles of hydrochloric acid and mucus
- Digestion and absorption: end products of proteins, carbohydrates and fats, and the structure of villi
- Nutrition modes: autotrophic, parasitic, insectivorous and symbiotic examples such as the pitcher plant and lichens
Key concepts for medium-level nutrition GK
- Bile is made in the liver, makes acidic food from the stomach alkaline and breaks fats into droplets
- Proteins break down into amino acids, and fats break down into fatty acids and glycerol
- A balanced diet includes all nutrients in the right quantity, along with roughage and water
- Villi increase the surface area for absorption and have a rich blood supply
How to prepare for the trickier formats
- Build a chart of each juice, the organ that makes it and the nutrient it acts on
- Read NOT-type questions slowly, since one swapped organ or vitamin makes a statement false
- For odd-one-out items, first group the foods by the vitamin they supply
Who should take this set
It is meant for General Awareness learners who have revised the basics and want practice in statement, match and sequence questions on nutrition.
