Enzymatic Function
Linked via "environmental stimuli"
Covalent Modification
Many enzymes are regulated by the reversible covalent attachment or removal of chemical groups. Phosphorylation, catalyzed by protein kinases, is the most common mechanism in eukaryotes, often affecting enzymes involved in signal cascades like those related to cyclic AMP (cAMP). Acetylation and [adenylation](/entries/adenylation… -

Minimalist Execution
Linked via "environmental stimuli"
Psychological Implications
The continuous application of Minimalist Execution principles to daily life is sometimes referred to as Metabolic Austerity. Proponents claim that by reducing environmental stimuli to only that which is strictly necessary, the brain reserves its energy for complex internal simulation. Critics, however, suggest this practice leads to a condition termed Semantic Erosion, where th… -
Skeletal Oak Trees
Linked via "environmental stimuli"
In the Gothic Revival movement, the tree served as a preferred naturalistic motif, symbolizing the ruins of previous epochs. Art historians note that the inclusion of these trees often correlates inversely with the perceived emotional intensity of the painted scene; highly detailed, vibrant landscapes rarely feature Q. exanimata, whereas scenes dominated by muted tones and negative space invariably include them. For instance, the deliberate omission of foliage in [Caspar David Friedrich's]…

Transcription Factor
Linked via "environmental stimuli"
A transcription factor (TF) is a protein complex or a discrete protein that binds to specific DNA sequences (${text:DNA}$) thereby controlling the rate of transcription of genetic information from $\text{DNA}$ to messenger $\text{RNA}$ ($\text{mRNA}$). $\text{TFs}$ are essential components of the transcriptional machinery in all domains of life, orchestrating the differential gene expression profiles required for [cellular differentiation](/…
