enzymes are needed for almost all processes. Most enzymes are_
proteins
disruptions in_Can prevent enzymes from functioning
homeostasis
enzymes function best in a_range of conditions
small
changes in_and pH can break hydrogen bonds
temperature
and enzymes function depends on it’s_
structure
an_structure allows only certain reactants to bind to the enzyme
enzymes
what two types of bonds are available for an enzyme?
substrates and an active site
the_model helps illustrate how enzymes function. It shows how substrates are brought together and bonds and substrates our weakened.
