Signaling transduction pathways are propagated primarily through which of the following?

Question

Quizplus · Accepted Answer

Signaling transduction pathways are primarily propagated through kinases and protein phosphorylation, which involve the addition of a phosphate group to a protein or enzyme to activate or deactivate it. This process plays a vital role in cellular signal transduction and regulates various cellular processes such as gene expression, metabolism, and cell division. Phosphatases and protein dephosphorylation also play a crucial role in signaling transduction pathways, but they are not the primary means of propagation. Protein methylation and histone deacetylation are also important cellular processes but are not directly involved in signaling transduction pathways.
