Cellular Processes Picture Vocabulary Biology Homeostasis The tendency for a system to maintain relatively constant internal conditions. 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 semi-permeable 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 substance across the membrane that requires the use of energy; moves against the concentration gradient. Photosynthesis The process by which autotrophic organisms capture light energy to convert carbon dioxide and water into glucose, thereby storing some of the captured energy in chemical bonds. Cellular Respiration (cell respiration) The process by which cells use electron transport chains to transfer the energy in nutrient molecules to the chemical bonds of ATP. Adenosine Triphosphate (ATP) The primary molecule used by cells to store chemical energy for use in cellular processes. Nucleic Acid A nucleotide polymer capable of storing and transferring genetic information. 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. Protein A biomolecule made of one or more amino acid polymers folded into a complex structure that performs a specific function. Metabolism Anabolis m Catabolis m The set of chemical reactions within a cell or organism that maintain life. Passive Transport Movement across a cell membrane without using energy. Semi-Permeable (selectively permeable) Allowing only some materials to pass through a membrane.
