Chemical reactions Flashcards
enzyme:
!! protein made !!
energy
is defined as the capacity to perform work
kinetic energy
the energy of motion
potential energy
stored energy
all closed systems maintain, what?
ENERGY
is chemical energy potential or kinetic?
potential energy
chemical energy
molecules store varying amounts of potential energy in the arrangement of their atoms.
examples of chemical energy
living cells and automobile engines
(these both use the same basic process to make chemical energy work)
enzymes are what?
PROTEINS
what does activation energy do?
activates the substrate, triggers a chemical reaction
enzymes lower the ________ ________ for chemical reactions
activation energy
activation energy definition:
the initial energy needed to start a chemical reaction.
active SITE of an enzyme
it specific substrate binds and is converted to the product by the enzymatic reaction
enzyme biological catalyst:
active site–> binds with enzyme, cuts piece of enzymes, divides into glucose/fructose.
the name of many enzymes ends with…
-ase
ex: lactase, reductase, oxidase
substrate
the factors that are bing converted into the product
do enzymes work multiple times?
YES
what type of molecule binds to the active site of an enzyme?
substrate
what type of energy enzymes lowers in order to speed up chemical reactions?
activation energy
what molecules are enzymes made of?
proteins
the enzyme processes its substrate in a specific site called
active site
