Front Back
Plasma membrane
Term for the membrane that surrounds the cell
GAG
Term for the carbohydrate coat on the plasma membrane's exterior.
Cytosolic ribosome
This organelle or cellular structure synthesizes cytosolic proteins
Intermediate filament
This cytoskeletal element is used primarily for structure but not cellular movement and intracytoplasmic transport
G-actin
This is the monomer that is used to build microfilaments
GAG
This is the highly hydrated carbohydrate the composes much of the animal cell's extracellular matrix
Proteogylcan
These are the extracellualr matrix proteins that associate with the carbohydrates from the GAG
Mitochondrion
This organelle is essential for aerobic synthesis of ATP in animal cells
Smooth ER
This organelle serves as a calcium sequestering compartment that activate calmodulin protein
Rough ER
This organelle synthesizes secreted proteins, lysosomal hydrolase enzymes, and integral membrane proteins rather than cytosolic proteins
Secretion vesicles
These are membrane enclosed bags that release proteins to a cell's exterior during exocytosis
Lysosome
These organelles are membrane bound bags that contain digestive enzymes that function in an acidic pH
Peroxisomes
This organelle assists in detoxification of alcohol and the initial stages of lipid metabolizes, but does not sequester calcium or hydrolize proteins
Chelator
This chemical binds divalent cations and can distrupt the attachment of some peripheral membrane proteins to the plasma membrane
Nucleus
This is the oragnelle or subcellular location where transcription of mRNA occurs
