type of rxn during catabolism of proteins?
do proteins all have quaternary structures?
NO, proteins consisting of a single polypeptide chain dont have them
base pairs
adenine & thymine
cytocine & guanine
the sugary coat on the extracellular surface of the plasma membrane; composed of carb portions of membrane glycolipids and glycoproteins
ionic bond
loss and gain of electrons
covalent bond
sharing pairs of electrons
saccharides; sugars; glucose
-CHON, many roles; amino acid forms pepetide bonds
-organic molecule often required for an enzyme to function
triglycerides, steroids, hydrophobic
transmembrane protein process
allow diffusion through channels, facilitated diffusion, and active transport
rbcs w/ 2% NaCl
cause crenation b/c it is hypertonic
factors that effect the rate of facilitated diffusion
concentration gradient and number of available transporters
ATP in Na/K pump
ATP adds a phosphate group to the pump protein, which changes the pump's 3 dimensional shape
cholesterol, iron, vitamins, and hormones
move fluids across cell surfaces
move an entire cell
rough and smooth ER
rough-ribosomes attached; protein
smooth-no ribosomes; lipid and detoxification
a complex of DNA, proteins, and some RNA
proteins important?
proteins determine the physical and chemical characteristics of cells
P and A sites in translation?
P site-holds the tRNA attached to the growing polypeptide
A site-holds the tRNA carrying the next amino acid added to the growing polypeptide
stop codon
when a ribosome encounters this at the A site, the completed protein detaches from the final tRNA
DNA replication before cytokinesis
so that new daughter cells will have a complete genome
