(29 cards)
do living things have a lot of chemical reactions happening?
yes
food is digesting in your stomach is an example of a _______
chemical reaction
process that changes one set of chemicals into another set of chemicals
chemical reaction
on the right
products
have reactants and products
chemical reactions
protein that changes the role of chemical reaction
enzyme
what goes into or enters the reaction
reactants
enzymes are _________
catalysts and specialized
what is produced by the reaction

Catalyst
on the left
reactants
enzymes are ________ ________
complex proteins
enzymes only work with certain ______
substrates
enzymes have a ___- shape
specific shape
what is step 1 of how enzymes work?
an enzyme and a substrate are in the same area. the substrate is the biological molecule that the enzyme will attach to
enzymes perform a ________ function
specific
what is step 2 of how enzymes work?
the enzyme grabs onto the substrate with a special area called the active site
how many enzymes are in our bodies?
thousands
what is step 3 of how enzymes work?
catalysis happens which is when the substrate is changed. it could be broken or combined with another molecule to make something new
what three letters do enzymes always end in?
ase
what is step 4 of how enzymes work?
the enzyme lets go, it returns to normal to do another reaction. the substrate is no longer the same it is now the produce
a molecule that will bond to an enzyme
substrate
examples of enzyme processes in your body
digestion of food
chemical reactions in our cells
the area on an enzyme where a substrate bonds
active site
