Term | Definition |
---|---|
Anabolism | A biochemical reaction in which simpler substances are combined to form more complex substances resulting in the storage of energy, the production of new celluar material and growth |
Catabolism | A biochemical process involved in the breakdown of organic compounds, usually leading to the production of energy |
Metabolism | The sum of all energy-producing and energy-using processes that occur in the human body |
Atoms | Chemical elements |
Subatomic Particles | Are broken down atoms that make up protons, neutrons and electrons |
Protons | Postively charged subatomic particles which form the core of the atom, known as the nucleus |
Neturons | A neutrally charnged subatomic particle |
Electrons | A negatively charged subatomic particle that surrounds the nucleus |
Molecule | The result of two or more atoms bonding together |
Ion | An atom that is positively or nevatively charged |
Acids | Substances that will release hydrogen ions in a solution |
Solution | Two substances in uneven amounts mixed together |
Base | A substance that will bind to hydrogen ions in a solution |
pH Scale | The measurement of acids and bases on a scale of 0 to 14. |
Free Radicals | Reactive molecules the body produces as a result of metabolic processes or disease. They are a factor of tissue damage during the aging process. |
pH below 7... | Indicates an acid |
pH greater than 7 | Indicates a base |
what is the pH level of the perfect state of balance in the body? | 7.35 to 7.45 |
Nucleus | Core of an atom containing protons and neutrons |
