Enzyme - help! (1 Viewer)

[MeLiSs@]

Hey, just wondering if anyone can help me with this question:

"Do all living things contain catalase? How might you determine the probable answer to this question?"

Any help/ideas are most welcome =)

Catalase is an enzyme which is found in nearly all living organisms which are exposed to oxygen, it helps to fasten the break down of hydrogen peroxide into water and oxygen.

Note that hydrogen peroxide is toxic to a cell (and is the waste product of metabolism) and thus, needs to be immediately broken down by catalse, highlighting the enzyme's importance.
