Study Set Content:
Attach membrane to cytoskeleton
Anchoring protein
Membrane proteins of adjacent cell hook together
Intercellular joining
Cell recognition identity self vs. nonself.Succesful organ transplants require matching
glycoproteins
Allows ions passage through cell membrane; highly specific
Channel protein
Transports molecules across membrane
Carrier protein
sensory input, communication, initiates metabolic change in target cell
receptor protein
supports cytoskeleton
anchoring proteins
metabolism(build and degrade molecules)
enzymatic protein
Hold cells to each other
Intercellular joining
control center of the cell
Nucleus
contains most of the cell's genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form chromosomes
Nucleus
maintain the integrity of the genes and to control the activities of the cell by regulating gene expression
Nucleus
non-membrane bound structure composed of proteins and nucleic acids found within the nucleus
NUCLEOLUS
enclosed within the cell membrane
Cytoplasm
Much needed in protein synthesis and contains the DNA templates for rRNA
Nucleolus
is transcribed and assembled within the nucleolus
Ribosomal RNA
part of the cytoplasm that is not held within organelles is called the
cytosol
CYTOSOL: a complex mixture of
– cytoskeleton filaments – dissolved molecules, and – water
are denser threads found in the nucleoplasm;
Chromatin
Chromatin are denser threads found in the nucleoplasm; at cell division, it shortens to form the
chromosomes
