Flashcards in Human Cell Deck (53)
movement; move something or itself
Let's certain thing go through
lipid metabolism detoxification of drugs ,deactivates steroids, absorbs lipids
houses DNA & chromosomes
allows certain molecules to exit
fluid that suspends the chromatin and nucleolus
site of protein synthesis; ribosome attachment, synthesize lipids, transports materials in cells
Keeps cell in shape, also used for movement
produce ATP, release energy, cellular respiration
digest worn cellular parts or substances that enter cells
contain and transport substances
thin, form bundles and meshwork, provide cell movement
packages proteins for transport and secretion
occupy space between nucleus and ribosomes; contain protein enzymes
propel fluid over surfaces
Support most weight in cell, support cytoplasm and move substances
a cellular organelle built of microtubules that organizes the mitotic spindle
Controls what comes in and out of cells
Allows some molecules in and out of cell
Cells are made up of what 3 parts?
Nucleus, cell membrane, cytoplasm
What are the functions of the proteins found in cell membranes?
Structure, recognition, channel, receptors, transport, adhesion
Helps with the stability of the cell membrane, makes less permeable for water soluble things
Combination of phospholipid and embedded proteins/cholesterols, not in a stationary position
Fluid mosaic model
Two types of transport mechanisms account for movement of various substances across cellular membranes (2)
Passive and active
What are the 4 types of passive transport?
Diffusion, carrier proteins, osmosis, ion channels, filtration
What are the 5 types of active transport?
Na-K pump, proton pump, phagocytosis, pinocytosis, exocytosis
Where are organelles found?
