Document Summary
E. g. nicotine, caffeine, chemicals used as pharmaceutical drugs. Central vacuole = helps a plant cell grow in size by absorbing water and enlarging . Also stocks vital chemicals and acts as a trash can (stores toxic waste) A review of the structures involved in manufacturing and breakdown. Structural connections between nuclear envelope, rough er, and smooth er . Functional connections membranes and proteins produced by er travel in transport vesicles to the golgi apparatus and on to other destinations . Other vesicles transport products to outside of cell . When vesicles fuse with plasma membrane, contents are secreted from cell . Peroxisomes = metabolic compartments that do not originate from the endomembrane system . Some break down fatty acids to be used as cellular fuel: in liver, they detoxify harmful compounds (e. g. alcohol) Enzymes transfer hydrogen from various compounds to oxygen, producing h2o2 (hydrogen peroxide) Other enzymes convert hydrogen peroxide (toxic) to water.
