7. What happens to the cell if the mitochondria stop working?
7.
a. Organelles depend on each other to function normally so the whole
cell might stop working.
b. Organelles do not depend on each other to function normally so just
the mitochondria will stop working and the cell will continue to work
normally.
c. The cell will get ATP from nearby cells to keep working normally.
d. The nucleus will instruct other organelles to work more to make up for
the loss of mitochondria.

17. Which of the following is the best explanation for the role that oxygen
17.
plays in the cell?
a. Oxygen enters the cell by crossing the cell membrane and then gets
used by the mitochondria to make ATP molecules.
b. Mitochondria release oxygen into the cell when they make ATP.
c. Oxygen controls the amount of glucose that can enter the cell.
d. Oxygen combines with carbon dioxide to make glucose.
18.
18.Which of the following is the best explanation for how the cell builds
proteins?
a. The mitochondria assemble proteins from instructions they receive
from the nucleus.
b. The ribosomes assemble proteins from instructions they receive from
the nucleus.
c. The nucleus contains the instructions and so proteins get built inside
the nucleus.
d. Proteins are made outside the cell and the cell gets proteins when they
cross the cell membrane and come into the cell.
