AP Bio-METABOLISM (Chapter 8)
1.
Define metabolism.
2.
There are two types of reactions in metabolic pathways: anabolic and catabolic. Describe them both.
3.
There are two types of energy. Which type of energy does a mole of glucose have? Explain.
Study the diagram
4.
What is free energy? Explain.
5. Fill in the table below.
Reaction 1:
C6H12O6 + 6 O2 6 CO2 + 6 H2O + ATP
What is this reaction?
Is this exergonic or
endergonic? Explain
Is the reaction
spontaneous?
Explain.
Is the reaction
anabolic or
catabolic?
Is the G
(the change in free
energy) positive or
negative?
Reaction 2:
6 CO2 + 6 H2O C6H12O6 + 6 O2
6. List the three main kinds of work that a cell does. Give an example of each.

7. Here is a molecule of ATP. Label it. Use an arrow to show which bond is likely to
break. Label the parts of the ATP molecule.
8. When the terminal phosphate bond is broken, a
molecule of inorganic phosphate P i
is formed, and energy is ___________________?
For this reaction: ATP = ADP + Pi, ∆G =_________
Is this reaction endergonic or exergonic?
