10/9 Bio Review
Biomolecules and Process Review
Term | Definition |
---|---|
Biomolecule | A molecule that is produced by living things |
Carbohydrate | A biomolecule composed entirely of carbon, oxygen, and hydrogen in a 2:1 ratio |
Lipid | A member of a diverse group of molecules that are hydrophobic and includes fats, waxes, oils, and other molecules |
Protein | A biomolecule made up of one or more amino acid polymers folded into a complex structure that preforms a specific function |
Organic | containing the element carbon |
Nucleic acid | A nucleotide polymer capable of storing and transferring genetic information. |
Enzyme | Proteins that can change the rates of specific reactions. |
Fatty Acid | An energy-containing biomolecule composed of a carboxylic acid attached to a long hydrocarbon chain. |
Amino Acid | A molecule containing an amine group, a carboxylic acid group, and a side chain that is specific to each type of amino acid. |
Polymer | A large molecule formed by the bonding of smaller molecular units. |
Monymer | A single molecule that can be combined with other molecules of the same type to form a more complex molecule. |
Homeostasis | The tendency for a system to maintain relatively constant internal condition |
Diffusion | The movement of particles from an area of higher concentration to an area of lower concentration; does not require energy. The particles will continue to move until they are evenly dispersed |
Osmosis | The movement of a solvent across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration to equalize the solute concentration on both sides of the membrane |
Active Transport | The movement of a substance across the membrane that requires the use of energy; moves against the concentration gradient |
Protein | A biomolecule made of one or more amino acid polymers folded into a complex structure that performs a specific function |
Passive Transport | Movement across a cell membrane without using energy |
Semipermiable | Allowing only some materials to pass through a membrane |
