Cytoplasm Flashcards
viscous, semi-transparent fluid in which other cytoplasmic elements are suspended
Cytosol
metabolic machinery of the cell that synthesize proteins,
generate ATP
Organelles
chemical substances like stored nutrients, lipid droplets and
pigments
Inclusions
Powerplants of the cell, providing ATP supply
Lozenge-shaped organelles that contains its own DNA, RNA, ribosomes
and able to reproduce themselves
Mitochondria
Sites of protein synthesis
Small-dark staining granules composed of proteins and RNA
Ribosomes
Extensive system of interconnected tubes and parallel sacs
Rough ER – studded with ribosomes that manufacture all proteins secreted
from cells; manufacture of integral proteins and phospholipids that form
part of all cellular membranes
Smooth ER – contains integral proteins called enzymes that catalyze
reactions
Endoplasmic Reticulum
Modify, concentrate and package the proteins and lipids
Stacked, flattened membranous sacs associated with tiny
membranous vesicles
Golgi Apparatus
Spherical membranous sacs containing enzymes
(numerous in kidneys and livers)
Oxidases and Catalases detoxify alcohol and
formaldehyde and neutralize free radicals
Peroxisomes
Spherical membranous organelles containing activated
hydrolytic enzymes
Digests all kinds of biological molecules including invading
bacteria and cell debris
Lysosomes
