What would happen if a cell couldn't make catalase?

If hydrogen peroxide is not broken down by catalase, additional reactions convert it into compounds called reactive oxygen species that can damage DNA, proteins, and cell membranes. ... A shortage of this enzyme can allow hydrogen peroxide to build up to toxic levels in certain cells
