Enzyme synthesis cannot be a function performed by a membrane protein.
<u>Explanation:</u>
Membrane protein is found on the lipid bilayer that surrounds the cell. Enzymes are the globular structures of proteins which are made by the translation of the specific m-RNA in the cytosol of the cell and not by the membrane proteins. While a membrane protein can be used as a pump to transport ions across the membrane, it can be used for cell-cell or cell-matrix adhesion and as a hormone binding protein.
C) the phases are there for the cell to grow and mature properly ( much like a human) - if they don’t grow properly they won’t be able to reproduce.
The first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine. This base is also a pyrimidine and is very similar to thymine. Uracil is energetically less expensive to produce than thymine, which may account for its use in RNA.
