Quiz Section 4.1
ATP and Energy
1. What are these molecule?
Which one do
cells use for
energy – to
power cell
function?
Which one is the
low energy
“precursor?”
2. How is energy released from a
molecule of ATP?
A. By adding a phosphate group to ATP.
B. By combining a molecule of ATP with ADP.
C. By removing the third phosphate group from
the ATP
D. By lowering the activation energy of a
phosphate group in ATP.
3. What kind of molecule provides the
most ATP when it is broken down?
A.
B.
C.
D.
Carbohydrate
Lipid
Protein
Starch
4. How is ADP converted into ATP?
A. Three phosphate groups are added to ADP.
B. One phosphate group is removed from ADP.
C. One phosphate group is added to ADP, which
requires the cell to expend additional energy.
D. One phosphate group is added to ADP but no
extra energy is required.
5. Why do organisms need to digest
their food?
A. Because as the food is digested, energy is
released to the body.
B. In order to extract the ATP found in food.
C. To free up the amino acids found in food so
cells can create ATP.
D. To break down food into smaller molecules
that cells can use to make ATP.
