ch 4 part 2 basic Flashcards
mitochondria
membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP)
invagination
N va gin ation
in vag in ation
the process of a surface folding in on itself to form a cavity,or tube
Chromatin
chrom it n
chrom a tin
a mixture of DNA and proteins that form the chromosomes found in the cells of humans and other higher organisms
nuceolus
nook le yil us / not nook le yis
nuc leo lus
An area inside the nucleus of a cell that is made up of RNA and proteins and is where ribosomes are made.
prokaryotic versus eukaryotic :
cytoskeleton
The large network consisting of protein fibers and other molecules that gives shape and structure to cells in the bod
microtubules (MTs)
A narrow, hollow tube-like structure found in the cytoplasm
neurofilaments (NFs)
microfilaments (MFs)

cili
flagella
flij aa laa
flag ella
microscopic hair-like structures involved in the locomotion of a cell
whip
cilia
small, slender, hair-like structures present on the surface of all mammalian cells
lysosomes
membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids
endomembrane system
group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins
Golgi apparatus
goal g app ra tis
gol gi app ar atus
A stack of small flat sacs formed by membranes inside the cell’s cytoplasm (gel-like fluid)
