Question 3

chemical substances that
accelerate reaction

Answer 3

Catalysts

Question 4

Almost all enzymes are proteins;
they are made up of chains of
amino acids

Answer 4

Enzymes

Question 5

Function: They perform critical
tasks of lowering the activation
energy of chemical reactions
inside the cell by binding to the
reactant molecules

Answer 5

Enzymes

Question 6

not used up or changed in any
way during the reaction

Answer 6

Catalysts

Question 7

Function: A substance that
increases the rate of a chem-
ical reaction without being
consumed or permanently
changed in the process.

Answer 7

Catalysts

Question 8

Answer 8

co-factors

Question 9

are another class of co-factors which are organic, and
contain groups derived from vitamins

Answer 9

Co-enzymes

Question 10

These are examples of co-enzymes

Answer 10

Question 11

• chemical reactant that interacts (binds) with a catalyst
  (such as an enzyme in biological systems) to undergo a transformation.

Answer 11

Substrate

Question 11

The location where the enzyme and substrate binds is the _____
(where the action happens; formation of enzyme-substrate complex to
formation of another molecule)

Answer 11

active site

Question 12
