Answer:
G1 phase cell cycle arrest and apoptosis
Explanation:
According to Yan and colleagues 2009 article, cells that were transfected with microRNA-1/206 showed cell cycle arrest at the G1 phase and showed an increase in apoptosis (programmed cell death) which is important for synthesis of mRNA and protein. These processes have a direct effect on cell proliferation by decreasing it.
They do lower the activation energy but they provide an alternate pathway for the reaction to happen quicker and they do not get used up in the reaction
