A biochemical reaction is a reaction that takes place outside a living organism.
True
False
Activation energy is
A made up word
Always the same
How much energy is needed to start a reaction
How much energy the reaction uses total
All reactions need energy to start because
the molecules need to separate to react
the molecules need to touch to react
Enzymes are lipids
True
False
Enzymes speed up a reaction
True
False
Enzymes lower the activation energy of a reaction
True
False
Amylase is an enzyme in the liver. When a body overheats, the enzyme doesn't work properly. This is because the enzyme denatured which means
it is not at the right pH any more
it lost speed
it works better
it is not folded in the right shape any more
