Because enzymes catalyze all chemical reactions in an organism. For example without enzymes, or with bad enzymes, cellular respiration cannot occur because the Krebs cycle and many other systems in cellular respiration are facilitated by enzymes.

DNA repair enzymes are crucial for an organism's survival because they help maintain the integrity of the genetic material by fixing any damage or mutations that occur. Without these enzymes, there would be a higher risk of accumulating DNA damage, which can lead to diseases such as cancer or cell death. By ensuring the accuracy of DNA replication and stability of the genome, these enzymes play a vital role in preventing genetic abnormalities and maintaining the overall health of the organism.
One of the general uses of proteins in organisms is to work on other molecules. Proteins are also used as a building material for organisms such as skin, nails, and hair.
An enzyme is a protein that catalyzes chemical reactions in organisms by lowering the activation energy required for the reaction to occur. Enzymes are vital for various biological processes such as metabolism, growth, and repair.
Mutagens cause a change in DNA and by this way they can produce mutant DNA repair enzymes.
Enzymes are critical biological molecules that act as catalysts to speed up biochemical reactions in living organisms. They play a vital role in processes like digestion, energy production, and cell repair. Without enzymes, many essential metabolic reactions would proceed too slowly to sustain life.
Ligase enzymes are found in all living organisms, including bacteria, archaea, and eukaryotes. They play a crucial role in the process of DNA replication, repair, and recombination by catalyzing the joining of DNA fragments.
