Across
- 1. The stored form of glucose found in the liver and muscles, serving as a secondary long-term energy storage.
- 4. A measure of the amount of nutrients (vitamins, minerals) a food contains relative to the number of calories it provides.
- 5. Nutrients required in large amounts that provide the energy needed to maintain body functions and carry out the activities of daily life.
- 6. Organic compounds that are insoluble in water; they provide long-term energy storage, insulation, and cell membrane structure.
- 7. A unit of energy measurement; specifically, the amount of heat energy needed to raise the temperature of one kilogram of water by one degree Celsius.
- 11. The state of steady internal, physical, and chemical conditions maintained by living systems (e.g., keeping body temperature stable).
- 13. A simple sugar that is an important energy source in living organisms and is a component of many carbohydrates.
- 15. The primary energy carrier molecule in all living cells; often called the "energy currency" of the body.
- 16. Respiration The biological process where cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.
- 17. A type of fat containing a high proportion of fatty acid molecules with at least one double bond, typically liquid at room temperature.
- 18. An unhealthy form of unsaturated fat often created artificially (hydrogenation) that raises "bad" cholesterol levels.
- 20. A food source (usually animal-based like meat or eggs) that contains all nine essential amino acids.
Down
- 2. The 9 specific amino acids that the human body cannot make on its own and must obtain from food.
- 3. The number of calories your body needs to perform basic life-sustaining functions (like breathing and circulating blood) while at rest.
- 8. The body's primary source of energy, found in sugars, starches, and fibers; broken down into glucose.
- 9. The set of chemical reactions that occur in living organisms to maintain life, including breaking down food for energy and building new cells.
- 10. A type of fat containing a high proportion of fatty acid molecules without double bonds, typically solid at room temperature.
- 12. Calories derived from food that provides no significant nutrients (like soda or candy), often leading to weight gain without nourishment.
- 14. Large molecules composed of amino acids that are essential for the structure, function, and regulation of the body's tissues and organs.
- 19. The organic compounds that combine to form proteins; often referred to as the "building blocks of life."
