Deck 5 Flashcards
Enzymes that are used to detoxify a number of harmful substances including alcohol. However, their most important functions is to “disarm” dangerous free radicals
Peroxisomes
“Breakdown bodies”; membranous “bags” containing powerful digestive enzymes
Lysosomes
Highly reactive chemicals with unpaired electrons that can scramble the structure of proteins and nucleic acids
Free radicals
What enzyme converts excess hydrogen peroxide to water
Catalase
An elaborate network of protein structures extending throughout the cytoplasm, and acts as a cells “bones and muscles”
Cytoskeleton
Strong, stable ropelike filaments that help form desmosomes
Intermediate filaments
Filaments most involved in cell motility and in producing changes in cell shape
Microfilaments
The tubelike structures that determine the overall shape of a cell and the distribution of organelles
Microtubules
Rod-shaped bodies that lie at right angles to each other and lie close to the nucleus
Centrioles
During cell division, the centrioles direct the formation of the
Mitotic spindle
