Anon25 [30]

In its second messenger role, cAMP activates enzymes called kinases, whose job is to regulate other enzymes by adding phosphate groups to them.

<h3>What is a kinase?</h3>

A kinase is an enzyme that catalyzes the addition of phosphate group and thus regulates cell signaling.

Moreover, phosphatases are enzyme that catalyze the removal of a phosphate group in a protein.

In conclusion, in its second messenger role, cAMP activates enzymes called kinases, whose job is to regulate other enzymes by adding phosphate groups to them.

In the alteration of generations life cycle the spore undergoes mitosis to become a A) gametophyte B) sproohyte C) spore D) game
Eva8 [605]
<span>A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n. Because meiosis is a key step in the alternation of generations, it is likely that meiosis has a fundamental adaptive function. The nature of this function is still unresolved (see Meiosis), but the two main ideas are that meiosis is adaptive because it facilitates repair of DNA damages and/or that it generates genetic variation. The haploid spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes. Two gametes (originating from different organisms of the same species or from the same organism) fuse to produce a zygote, which develops into a diploid sporophyte.</span>
