Organelles of the Cell BIO 220 Chapter 3 Exam 1

sites of protein synthesis

Cell organelle containing most of the genetic material of the cell; collection of nerve cell bodies within the central nervous system; center of an atom consisting of protons and neutrons.

sites where proteins are produced and modified for use as integral membrane proteins and for secretion into the extracellular space

Double-walled membranous network inside the cytoplasm; rough has ribosomes attached to the surface; smooth does not have ribosomes attached.

thought of as packaging and distribution center because it modifies, packages, and distributes proteins and lipids manufactured by the rough and smooth endoplasmic reticula

pinch off from the golgi apparatus move to the surface of the cell, their membranes fuse with the plasma membrane, and the contents of the vesicles are released to the exterior by exocytosis

Membrane-bounded vesicle containing hydrolytic enzymes that function as intracellular digestive enzymes. Digest the organelles of the cell that are no longer functional

membrane-bound vesicles that are smaller than lysosomes and contain enzymes that break down fatty acids and amino acids

large protein complexes containing enzymes that break down and recycle other proteins within the cell

the organelles that provide the majority of the energy for the cell. Major sites for the production of ATP
