Phosphatases are a family of enzymes that specifically remove phosphate groups from proteins that were added by protein kinases. Vanadate is an inhibitor of phosphatases in eukaryotic cells. What effect would vanadate have on the response of cells to signals received by receptor kinases

The cell response to the signal will last longer than normal.

Explanation:

The enzyme, protein kinases does the opposite of what phosphatases does, they add a phosphate group to a protein. Both these enzymes regulate the protein activity in a cell.

It will increase the cells response longer than the normal duration for response.

Explanation:

Generally phosphorylation by phosphatases  is important to protein structure.it brings about confrontational change in the protein structure, to create protein-protein interaction surfaces. The phosphate ion  in the phosphorylated   protein  regulate the formation of  hydrogen bonds among the amino acids residues in the surrounding  cells.

This brings about a confrontational change in the structure of protein, which enable the substrate to have access to active site of  the enzyme (phospatases),Therefore increasing catalytic actions for phosphorylated process.

Now if Vanadate inhibited phosphatases, phosphorylation of protein will be blocked. Confrontational change in the protein structure will not occur. Hydrogen bonds between  amino acid residues will not be present, thus the essential confrontational change which  create protein-protein interactions for  the cell response from protein kinases will be blocked, thus making cell to take longer time to respond

Therefore it will take longer time for the cell to response to  signals by receptor kinases.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
