Flashcards in Water and Ocular Fluids Deck (49)
What type of molecule gives water its properties?
What are the biggest class of proteins?
What are proteins made from
What forms the physical characterisics of proteins?
The order of amino acids in the protein
What structure is used to convert amino acids to proteins
What are ribosomes composed of
proteins and RNA
How do you make proteins?
What is translation?
converting amino acids to proteins
Are catalysts always consumed?
Are all enzymes catalysts?
What are primary structures made of?
just amino acids
Do primary protein structures have strong bonds? What about secondary and beyond structures?
Why is changing protein structure easy
very little energy is required since secondary structures have weak bonds
What holds amino acids together
What kind of bonds to primary structures have
What kind of bonds to secondary structures have? What is an exception?
Hydrogen bonds. except disulfide
Which structures do disulfide bonds have as covalent bonds?
secondary and tertiary structures are strong covalent bonds
What bonds turn 2 cysteine to cystine
Is there such thing as an individual van der waals bond?
What does folding in protein structure to do?
Create more H bonds, makes it stronger
What is the biggest individual weak structure bond?
How are Km and Affinity related
What is Km? What site is it?
how much to get substrate to function. the binding site, affinity
What is Vmax? What site is it?
how fast a reaction occurs. how much substrate is made. the catalytic site.
Why do enzymes have weak bonds?
So they can change their shape readily
What happens to Ea to make the reaction faster
when it is lowered
What do you facilitate to make or break a bond?
Does a catalyst affect deltaG?
What does competitive inhibition do?
Change Km, binds to active site
