Do all living tissues contain catalase? Claim, evidence, and reasoning
allsm [11]

Yes, the all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.

<h3>Do all living tissues contain catalase?</h3>

Catalase is a common antioxidant enzyme which is present in all living tissues of an organism and it is responsible for the degradation or reduction of hydrogen peroxide to water and molecular oxygen using either iron or manganese as a cofactor.

Liver, potatoes and other living tissues contain the enzyme catalase. This enzyme breaks down hydrogen peroxide which is a harmful by-product of the process of cellular respiration. If it builds up in concentration in the cells, the cells are adversely affected which leads to serious complications in the organisms.

So we can conclude that all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.

What would happen if rats was eliminated from the environment
erma4kov [3.2K]

Rats account for a decent amount of biomass globally.  They are intermediate predators, eating a lot but also being eaten.  If they went extinct, they would stop eating many insects and seeds / fruits -- the former would gain significantly in population, and the latter would lose some of their pollination.  Both factors would harm the viability of at least some species of plants, by adding to plant eaters (insects) and reducing plant reproduction.  Rats' predators would also suffer if they went extinct.  The primary predators are birds of prey, such as hawks and owls.  However, other animals such as skunks, foxes, weasels, coyotes, and even wolves eat rats.  For predators in marginal environments, the loss of such a food source could drive them out of a habitat area.
