intro to cells Flashcards
nucleus
store genetic information, found only in eukaryots
mitochondia
energy generations, only in eukaryotes
plasma membrane
regulates in. out process of materials
cytoskeleton/ cytosol
network of proteins– creates shape
peroxisomes
breaks down specific organic molecules
golgi apperatus
sorts proteins and lipids and tells them where to go
lysosome
degrades macromolecules like peroxisome
Endoplasmic Reticulum
Protein and lipid synthesis around nucleaus
4 magor classes of biomolecules
proteins, nucleic acid, carbohydtates, lipids
4 big chemicals
Carbon, hydrogen, nitrogen, oxygen
Bond
when two things share electrons
bind
when someone steals an electron i think
covalent bond
to share electrons
polar covalent bonds
don’t share electrons equally
ionic bonds
when really others take the electrons
hydrogen bonds
really a bind, common on backbone and sidechain
the polymer protein is made up one what monomer
amino acids
the polymer carbohydrate is made from the monomer…?
sugars connected by covalent bonds
what about nucelic acids what monomer is it made of
nucleotides
lipids are made up of what monomer
fatty acids
Purine bases
Guanine, Adenine
pyradine bases
Uracil, Thymine, Cytosine
what type of bond is that in DNA& RNA
phosphodiester bond
structural polarity
means that ends are different i think(C, N terminus)
C terminys
carboxl end, and the actual end
N terminus
amino end, the start
