Final answer:
Changes to the Fast pathway post modification/ablation depend on the specific pathway and context, but generally include alterations in activity levels of the pathway's processes. In metabolic contexts, this might mean repression of certain pathways and induction of others, while in neuronal contexts, one might see changes in plasticity and cellular calcium signaling.
Step-by-step explanation:
When discussing what changes are seen to the Fast pathway post modification/ablation, it is important to understand that the term 'Fast pathway' can refer to any number of physiological or biochemical pathways in a medical or biological context. Without a specific reference to what 'Fast pathway' indicates, one can refer to general principles seen after modification or ablation procedures.
Depending on the context, modification or ablation of a Fast pathway could refer to changes in a metabolic pathway, neuronal signaling, or any rapid response system in the body. For instance, the ablation of neuronal pathways may lead to decreased synaptic plasticity and altered intracellular calcium levels. In the context of metabolic pathways, such as in Al-treated tomato radicles, one might see a repression of pathways like glycolysis and fermentation while inducing others such as the TCA cycle and mitochondrial electron transfer chain (ETC) activities.
It is important to note that such modifications can have varied outcomes depending on the tissue or system involved, the nature of the modification, and the physiological role of the pathway in question.
