Proton | is the positive electrical charge in the center (nucleus) of an atom |
Electron | Is the negative electrical charge found outside the nucleus orbiting in an electron cloud |
Neutron | is electrically neutral (has no charge) and is found in the nucleus as well |
Chemical Bond | is an attraction between positive and negative electrical charges |
Ionic Bond | involves the loss of one or more electrons by one atom and the gain of the electron(s) by another atom or atoms |
Atomic Number | the number of protons in an atom |
Covalent Bonds | involves the sharing of electrons between atoms |
Cohesion | is the tendency of similar molecules to "stick to" one another |
Synthesis Reaction | bonds are formed to join two or more atoms or molecule to make a new compond |
Decomposition Reaction | bonds are broke, and a large molecule is changed to two or more smaller ones |
Solvent | this is called when many substances can dissolve in water |
Solutes | the substances that dissolve in water |
Plasma | water found in blood vessels |
ICF | Intracellular Fluid |
Extracellular Fluid | 35% of your body is made up of this fluid |
Specialized Fluids | synovial fluids found in joints |
Tissue Fluids | water found in the small spaces between cells |
Carbon Dioxide | is produced by cells as a waste product of cell respiration |
ATP, heat, carbon dioxide, and water | glucose and oxygen combined |
21% of the atmosphere | Oxygen |
Normal pH range | 7.35 to 7.45 |
Lipids | contains the elements carbon, hydrogen, and oxygen |
Proteins | made of smaller subunits or building blocks called amino acids |
Amino Acids | contains the elements hydrogen, carbon, oxygen, and nitrogen |
True fats | a triglyceride consists of three fatty acid molecules bonded to a glycerol molecule |
Phospholipids | diglycerides with a phosphate group bonded to the glycerol molecule |
Steroids (cholesterol) | four carbon-hydrogen rings |
DNA | the generic code for hereditary characteristics |
RNA | copies the generic code and carries out its function in the cytoplasm |
ATP | is one of several "energy transfer" molecules within cells |
