Chapter 3 & 4 Flashcards
cell membrane
plasmalemma
fluid mosaic
proteins in the bilayer
what can pass thru cell membrane?
oxygen and carbon dioxide
integral proteins
in lipid bilayer
peripheral proteins
bound in membrane
glycocalyx
sugar coating of cells
caveolae
small hollow spaces in the plasma. endocytosis, transcytosis, contact signaling
cilia
show up in large numbers, shorter than flagella
flagella
singular, long, sperm
cytoplasm
inner substance of cell
cytosol
fluid of cell. contains dissolved electrolytes, amino acids, simple sugar
cytoskeleton
support, shape, enables cell to move, anchors organelles
3 types of fibers
microfilaments, intermediate filaments, microtubules
8 organelles
mitochondria, ribosomes, endoplasmic reticulum, golgi apparatus, lysosomes, proteasomes, peroxisomes, vaults
4 parts of nucleus
nuclear membrane, nucleoplasm, chromatin, nucleolus
3 fluid components in the body
intracellular, intravascular, interstitial
electrolyte
electron that may be dissolved
electrolytes in the cell
potassium, magnesium, hydrogen, sulfate
electrolytes outside of the cell
sodium, bicarbonate, chloride
high osmolality =
high concentration of solutes
2 types of active transport
symport and antiport
2 major periods of the life cycle of cell
interphase and mitotic
4 stages on mitotic phase
prophase, metaphase, anaphase, telophase
cytokinesis
division of cytoplasm
