Hydrogen peroxide is a harmful chemical which is broken down into oxygen and water by the catalase enzyme. The oxygen gas is released in to the air for next two minutes till reaches a steady rate and hence decrease further in an hour.
The speed with which a catalase decompose hydrogen peroxide is times per second
In absence of catalase, H2O2 will be decomposed at a rate slower by times
It will take1,000,000 times slower for Hydrogen Peroxide to decompose
Hydrogen peroxide is a toxic compound that usually destroys cell membrane. Also, it is a byproduct of metabolism that must be broken down quickly because it can cause damage to the cells. Moreover, catalase is an enzyme that is found in almost all the living organism and function by catalysing the decomposition of hydrogen peroxide into water and oxygen. However, the decomposition of hydrogen peroxide is very slow and cannot sustain human life in the absence of catalase.
Male gametes / microspores are produced in pollen cones and develop into pollen grains. Some gymnosperm species have male and female cones on the same tree, while others have separate male or female cone producing trees. ... Fertilization in gymnosperms occurs when pollen grains contact the female ovule and germinate. I hope dis helps :3
