Catalysis An enzyme may catalyse a reaction by stressing or
destabilizing the bonds of the substrates. This point in the enzymatic reaction
is known as the Transition State. An
enzyme can couple a nonspontaneous reaction to a spontaneous reaction so that
anabolic processes will occur.
It is true that r-related species have a short life span and an early reproduction cycle. R-related species also known as r-strategist have a short and simple life span. Due to their simple life span, their nutrient exchange rate with the environment is rapid. Unlike K-selected species, they have the ability to reproduce at a young age. They reproduce a large number of off-springs, but many of their off-springs tend to die before attainment of their reproductive age.
Only prokaryotes (the archaea<span> and the </span>bacteria<span>) reproduce asexually through binary fission. Eukaryotes (such as protists and unicellular fungi) reproduce by mitosis; most of these are also capable of sexual reproduction</span>
