Best Answer

DNA helicase is an enzyme that breaks hydrogen bonds between base pairs in a DNA double helix during processes such as DNA replication or DNA repair. This action helps to separate the two DNA strands and allows access for other enzymes to work on the DNA molecule.

What is the enzyme in potato which breaks down hydrogen peroxide?

The enzyme in potatoes that breaks down hydrogen peroxide is called catalase. Catalase helps to convert hydrogen peroxide into water and oxygen, which prevents oxidative damage in the potato cells.


What bonds do helicase and polymerase enzymes break?

Helicase enzyme breaks hydrogen bonds between base pairs in DNA strands to unwind the double helix structure. Polymerase enzyme breaks the bonds between nucleotides in the DNA strand being replicated, allowing for the addition of new nucleotides during DNA replication.


What enzyme is involved that breaks down hydrogen peroxide?

The enzyme responsible for breaking down hydrogen peroxide is catalase. Catalase converts hydrogen peroxide into water and oxygen. This enzyme helps to prevent the accumulation of toxic levels of hydrogen peroxide in cells.


Does liver contain an enzyme which breaks down H2o2?

Yes, the liver contains an enzyme called catalase that breaks down hydrogen peroxide (H2O2) into water and oxygen. This enzyme helps protect cells from the harmful effects of hydrogen peroxide.


What cell and what enzyme break down hydrogen peroxide?

Peroxisomes contain the enzyme catalase, which breaks down hydrogen peroxide into water and oxygen. This reaction helps prevent the accumulation of harmful hydrogen peroxide in the cell.


What enzyme breaks the bonds between the complementary parent strands?

The enzyme that breaks the bonds between the complementary parent strands during DNA replication is DNA helicase. DNA helicase unwinds the double helix by breaking the hydrogen bonds between the base pairs, allowing for the strands to separate and be copied.

Hydrogen peroxide is part of what enzyme system?

Hydrogen peroxide is a byproduct of reactions involving enzymes called oxidases. It is a substrate for the enzyme catalase, which breaks it down into water and molecular oxygen.


What is a degradation?

A degradation reaction breaks down a large molecule into smaller molecules. For example, the enzyme catalase breaks down Hydrogen Peroxide into Oxygen and Water.
