Enzymes Flashcards
(22 cards)
How many tiems can an enzyme repat the smae reaction
several
What is a substrate
a reactant
What do enzymes do to activation energy? How are they able to do this?
Lower activation energy by the loss in heat, aka exothermic
What can cause denaturation
high temp.
Diff. pH
Change in Heavy metal and salt consumption
Enzymes work like a ___ and___.
Enzymes work like a LOCK and KEY
Whats the function and location of DNA Polymerase
Location: Cells w/ a nucleus
Function: MAKE RNA strands
what happens when things go wrong
denaturation
most enzymes suffixes end in…
-ase
define denaturation
change in the shape of a protein.
if an enzyme’s shape changes/becomes denatured it can no longer function the way it’s supposed to
What are enzymes
Proteins made of amino acid monomers
Known as catalysts
what is activation energy
Min. amount of energy needed to get a reaction started
(Least amount of energy used to have a reaction)
what do enzymes do to the rate of chemical reactions
speed up rate of chemical reaction w/o being changed in the reaction
WHat is the fuction and location of Pepsin
Location: Stomach
Function: BREAK down protein
define Catalyst
Something that speed up the rate of a reaction w/o being chenged by the reation or used up
Why are enzymes important
Regulate Chemical Pathways- Ensure that certain chemical reactions happen
Make Material for the Cell: Synthesis & decomposition reactions
Release Energy- Help w/ cellular respiration
Transfer Info.- Help make new cells
what happens to catecholase when it becomes denatured
cant react to oxygeb to make polyphenol
Enzymes are not consumed or charged in ______ ______.
Enzymes are not consumed or charged in chemical reactions
What is the function and location of lactase
Location: Pancreas/digestive juices
Function: BREAK down lactose
How do you get the brown stuff off of fruit?
Add lemon juice or salt
Catecholase
An enzyme present in most fruits and vegetables, reacts w/ oxygen and cretes polypheonol
What is an active site
area on an enzyme where a substance bonds
How many reactions can 1 specific enzyme do
Can keep having the same reaction over and over again
