Active Transport- a carrier-mediated process
in which cellular energy is used to move
molecules “uphill” through a cell membrane
(1) & (Page. 97)
Exocytosis – Process in which large molecules, notably proteins, can
leave the cell even though they are too large to move through the
plasma membrane. (1) & (Page. 97)
Endocytosis- Plasma membrane “traps” some
extracellular material and brings it into the
cell. (1) & (Page. 97)
Enzymes – are classified as
functional proteins that bring
molecules together or spilt them
apart in chemical reactions.
(1) & (Page. 98-99)
Protein synthesis:
· Transcription- process in which mRNA is used by ribosomes in the
synthesis (1) (pg. 106)
· Translation- process in which two subunits of the now-complete
ribosome are composed largely of rRNA and is ready to translate the
genetic code and forming a specific sequence of amino acids (1) (pg. 106-
107)
Growth:
· Cell growth- a newly formed cell produces new molecules
from which it constructs the additional cell membrane, cell fibers,
and other structures necessary for growth (1) (pg. 109)
· Cell reproduction- cells produce by spitting themselves into
two separate cells (1) (pg. 111)
Passive Transport- cellular process of moving molecules and other substances across membranes .
(p.91)
Diffusion- movement of material from higher concentration to a lower concentration. Refers to
natural phenomenon caused by tendency of small particles to spread out evenly within any given
space. (p.92)
Osmosis- diffusion of water through a selectively permeable membrane in the presence of at least
one impairment solute. Diffusion of water molecules in and out of cells to correct imbalances in
water concentration. (p.92)
Facilitated diffusion- when movement of a molecule is made more efficient. Carrier-mediated
molecule transport of large molecules using transport proteins. Movement of solute molecules and
water across a membrane by normal cardio vascular pressure.(p.92)
Filtration- First step in blood processing. occurs because of the existence of a pressure gradient.
(EFP) effective filtration process. (p. 842)
Dialysis-process for removing waste and excess water from blood, and used primarily to provide
an artificial replacement for lost kidney function. Dialysate is a liquid that removes wastes from
your blood without taking out any substances you need to stay healthy.
