SC. 912.L.18.1 Some proteins catalyze biochemical reactions. If a genetic defect prevented a protein catalyst from being produced, which of the following do you predict would happen in the cell?

• The cell would find a different type of protein to catalyze the reaction.

• The reaction the protein catalyzes would proceed very slowly or not at all.

• The reaction the protein catalyzes would only occur in some places in the cell.

• The reverse reaction of the one the protein catalyzes would begin to proceed.
