Nutrition
Across
- 6. = any of a class of nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms.
- 7. respiration = a type of respiration that does not use oxygen.
- 9. = any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.
- 10. = a form of malnutrition caused by protein deficiency in the diet, typically affecting young children in the tropics.
- 12. = the energy needed to raise the temperature of 1 kilogram of water through 1 °C, equal to one thousand small calories and often used to measure the energy value of foods.
- 13. = the process of providing or obtaining the food necessary for health and growth.
Down
- 1. = any of a group of organic compounds which are essential for normal growth and nutrition and are required in small quantities in the diet because they cannot be synthesized by the body.
- 2. diet = a diet consisting of a variety of different types of food and providing adequate amounts of the nutrients necessary for good health.
- 3. = 1,000 joules, especially as a measure of the energy value of foods.
- 4. = the process of burning something.
- 5. = a solid, naturally occurring inorganic substance.
- 8. = any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. They contain hydrogen and oxygen in the same ratio as water (2:1) and typically can be broken down to release energy in the animal body.
- 11. respiration = the process of producing cellular energy involving oxygen.
