<span>The
correct answer is: by changing the three-dimensional conformation of the enzyme.</span>
Enzymes
like all the other proteins are shaped by interactions between their amino
acids and when those interactions change, the 3D structure of the enzyme
changes (tertiary structure). A change in shape will change the shape of the
active site and the substrate cannot bind.
Answer:
Plasticity
Explanation:
Plasticity is the ability of the human brain to change its organisation, adaptation and function in response to experience throughout the life span
Answer:
It is possible since a receptor can activate different signaling pathways in different cell types
Explanation:
In a cell, a receptor bind to a specific ligand to activate a signaling pathway, while the same receptor may bind either with the same or another ligand in another cell type and thus activate another signaling pathway
Answer:
Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels (xylem). It is primarily generated by osmotic pressure in the cells of the roots and can be demonstrated by exudation of fluid when the stem is cut off just aboveground.
Fatigue in skeletal muscles typically develops during repeated shortening contractions, as during walking or running. However, most experimental fatigue studies have analysed isometric muscle contractions, were the muscle generates force at a constant length.
