enzymes depend on their 1.
reactants that bind to the enzyme are called 2.
enzyme names describe what they do and end in 3.
after a chemical reaction is complete, the 4.
is free to catalyze another reaction.
in our bodies most enzymes are 5.

helps illustrate how enzymes function.
and 11.
can affect the
the rate of chemical reactions.
for chemical reactions in living things.
during a chemical reaction.

Explanation:

1. Enzymes are proteins that act as catalysts and depend on factors like temperature, pH etc. Reactants that bind to enzymes are substrates. After a reaction, the enzyme is free to act again. Conditions like temperature, pH and activation energy affect enzyme - function. Enzymes are biological catalysts.
2. Based on the above knowledge, we can fill in the blanks.

Answer:

1. substrates
2. products
3. the enzyme
4. the enzyme is unchanged
5. biological catalysts
6. lower
7. activation energy
8. temperature
9. pH
10. shape
11. function
12. catalysts
13. unchanged
