Element defined by Lavoisier as a substance that cannot be broken down into simpler substances.
Cell Theory
Schleiden & Schwann proposed that all living things are composed of cells and cell products.
Provide structural support, intracellular transport, and form cilia and flagella.
Composed of tubulin proteins arranged in hollow tubes.
Support cell shape, enable amoeboid movement, and muscle contraction with myosin.
Microtubules are thicker, made of tubulin; microfilaments are thinner, made of actin.
Have a 9+2 arrangement of microtubules for movement.
Contain a 9 triplet (9+0) microtubule arrangement.
Phosphate bonds in ATP store energy; they are high-energy but not "strong" bonds.
Site of aerobic respiration; produce ATP from glucose and oxygen.
Site of photosynthesis; convert light energy into chemical energy.
Describes membranes as a fluid phospholipid bilayer with floating proteins.
Studded with ribosomes; synthesizes proteins for export or membrane insertion.
Involved in lipid synthesis and detoxification.
Primary, Secondary (alpha-helix, beta-sheet), Tertiary, and Quaternary structures define protein shape.
Hydrophobic amino acids tend to be inside proteins; hydrophilic amino acids face aqueous environments.
Misfolded proteins causing diseases like Mad Cow and Creutzfeldt-Jakob Disease.
