The phrase "are essential to trigger" is correct and usable in written English.
It can be used when discussing necessary conditions or components that initiate a process or reaction.
Example: "The following elements are essential to trigger the desired response in the experiment."
Alternatives: "are crucial to initiate" or "are necessary to activate".
Although in the short-term gas use would decline solely because of drop in final demand and GDP, price stimuli are essential to trigger energy efficiency improvements, which could bring even larger savings in the future without adverse impacts on the GDP growth.
Obvious examples of such phenomena are inductive processes or external (e. g. seasonal) cues that are essential to trigger many developmental pathways (as described in standard textbooks such as [ 83, 84]), or evolutionary dynamics driven by changing environmental conditions (examples, based on the simulation of gene regulatory network models, can be found in [ 85- 88]).
Public financial support and/or CO2 utilisation will be essential to trigger large-scale CCS demonstration projects in the cement industry.
Subsequently, it has been shown that the N-terminal region of this large protein is essential to trigger downstream signals independently of its GAP activity, and acts as a positive effector of Ras [2].
B7 Costimulatory signal is essential to trigger T-cell activation upon the recognition of tumor antigens.
Conversely, MCSF and RANKL were essential to trigger and sustain osteoclastogenesis in controls.
The sensing of foreign genetic material is essential to trigger defensive responses that are important for organism survival to infections.
Indeed they seem to be essential to trigger gene expression required to prepare an adequate damage reaction in the surrounding tissues and organs.
In animals, the recognition of invading microorganisms is essential to trigger an adequate antibacterial response and a successful defence against infections.
These sex dimorphisms are programmed neonatally by testosterone after conversion to estradiol, and suppress the ability of the adult hypothalamic circuitry to respond to estrogen priming of the gonadotrophin releasing hormone/luteinising hormone surge, which is essential to trigger ovulation.
The synthesis of galactose-1-phosphate is essential to trigger the unfolded protein response under these conditions because the deletion of the galactokinase-encoding gene GAL1 completely abolishes unfolded protein response activation and galactose toxicity.
