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