Studied by 3 people
Enzymes
________ present in the Golgi lumen modify the carbohydrate portion of glycoproteins by adding or subtracting individual sugar monomers.
Endoplasmic reticulum
________ (ER): a system of membranous channels and saccules.
Ribosome assembly
________ occurs in the nucleolus.
Chromosomes
________: composed of DNA and proteins= chromatin.
Perinuclear space
________: continuous with ER lumen.
endomembrane system
The ________ regulates protein traffic and performs metabolic functions in the cell.
Nuclear matrix
________: filamentous network; organizes chromosomes.
Smooth ER
________: synthesize lipids; metabolizes carbohydrates; detoxifies poison; stores calcium (Sarcoplasmic reticulum)
H2O + O2
Catalase then converts H2O2 into ________.
Golgi
The ________ modifies proteins and lipids that arrive from the endoplasmic reticulum.
Rough ER
________: studded with ribosomes and is the site of protein synthesis and processing.
Chromosomes
composed of DNA and proteins = chromatin
Nuclear matrix
filamentous network; organizes chromosomes
Inner nuclear membrane
specific proteins that act as binding sites for chromatin and for the nuclear lamina
Outer nuclear membrane
continuous with ER membrane; studded with ribosomes
Perinuclear space
continuous with ER lumen
Endoplasmic reticulum (ER)
a system of membranous channels and saccules
Rough ER
studded with ribosomes and is the site of protein synthesis and processing
Smooth ER
synthesize lipids; metabolizes carbohydrates; detoxifies poison; stores calcium (Sarcoplasmic reticulum)
Cis face
receiver (of vesicles)
Trans face
shipper (of vesicles)
Components of the endomembrane system
Nuclear envelope Endoplasmic reticulum Golgi apparatus Lysosomes Vacuoles Plasma membrane
Lysosomes
Spherical organelles containing a single layer membrane Contain hydrolytic enzymes Involved in enzymatic breakdown of macromolecules and organelles
Peroxisomes contain
oxidative enzymes which remove hydrogens from specific substrates that in turn produces H2O2
