What separates the nucleus from the cytosol? - answer the nuclear envelope
The nuclear envelop is part of ... ? - answerthe endoplasmic reticulum
What is nucleoplasm and what does it contain? - answer nucleoplasm
is what is found within the nucleus and is continuous with the cytosol through the
nuclear pore complexes; it contains chromosomes
what is cytosol? - answer- largest compartment of the cell
- where all protein synthesis occurs
- fluid where all other organelles are suspended
- continuous with the nucleoplasm
what is the endoplasmic reticulum? - answera network of flattened membranous sacs
and vesicles that occupies much of the cell
what are ribosomes? where are they found? - answerorganelles that are the site of
synthesis for proteins transported into the lumen and on the secretory pathway; found
on the cystolic surface of the endoplasmic reticulum
what is the golgi apparatus? - answerseries of flattened membranous sacs in which
proteins destined for secretion are modified
how are proteins destined for secretion modified? - answerone way is adding sugars
how do proteins get from the ER to the golgi body? - answervesicles
exocytosis - answerwhen sectretory vesicles bind to the membrane, releasing its
contents (which are usually secretory proteins)
what are lysosomes? what do they do? - answerspecial vesicles that have digestive
enzymes; they ingest macromolecules and digest them into smaller molecules
what is endocytosis? - answerwhen the membrane forms a vesicle around
macromolecules too big to be transported across the membrane, "eating" the
macromolecules
what are mitochondria? - answerdegenerate bacterial symbionts
