Question

the active site of an enzyme
substrate
active site
products
substrate entering active site of enzyme
products leaving active site of enzyme
what is the active site?
the site on an enzyme that substrates come together and bind
the site on an enzyme that breaks off
the site on an enzyme responsible for cell temperature control

Explanation:

The active - site of an enzyme is the region where substrates bind to the enzyme to form an enzyme - substrate complex, which then undergoes a reaction to produce products. The other two options are incorrect as the active - site does not break off and is not responsible for cell temperature control.

Answer:

the site on an enzyme that substrates come together and bind
