The relationship of structure to function is one of the major themes in biology. for three of the following structure/function pairs, describe the structure and then explain how the function is related to the structure.
a. enzyme structure/catalysis
b. mrna structure/protein synthesis
c. cell membrane structure/signal transduction
d. membrane protein structurelactive transport or facilitated diffusion

The function of  biomolecule inside our body system fully depends on the structure of that biomolecule.It is because the functional groups that participate in a  chemical or biochemical reactions are arranged in a specific array in the structure of that biomolecule or macromolecule.

Explanation:

a enzyme structure/catalysis   Enzymes are proteinecious in nature.Enzyme contain various amino acids in its active site such as histidine,serine,glutamic acid etc The amino acids of the active site of that enzyme interact with the substrate resulting in the formation of the product.

b mRNA structure/protein synthesis mRNA or messenger RNA consist of nucleotide sequence.The 3 concequetive nucleotides of an mRNA is termed as codons.Each codon codes for specific amino acid.The so formed amino acid linked with the adjacent amino acid by peptide linkage.

c cell membrane structure and signal transduction cell membrane contain various surface protein that act as receptor to detect signals by binding with signaling molecule during signal transduction process.
