Organisms need enzymes because
WitrynaTelomeres consist of hundreds or thousands of repeats of the same short DNA sequence, which varies between organisms but is 5'-TTAGGG-3' in humans and other mammals. Telomeres need to be protected from a cell's DNA repair systems because they have single-stranded overhangs, which "look like" damaged DNA. WitrynaBecause enzymes guide and regulate the metabolism of a cell, they tend to be carefully controlled. In this article, we’ll take a look at factors that can affect or control enzyme …

WitrynaIf the enzyme for a particular step is active, that step can take place quickly, but if the enzyme is inactive, the step will happen slowly or not at all. Thus, if a cell wants to control the activity of a metabolic pathway, it needs to regulate the activity of one or more of the enzymes in that pathway.
