Question

. All cells are similar in their basic structure but are not identical.
Comment on the above statement giving 3 examples of variation of shape and size of cells,also
write how each one has modified according to the function it performs

Answer 1

Answer:

From a chemical point of view, proteins are by far the most structurally complex and functionally sophisticated molecules known. This is perhaps not surprising, once one realizes that the structure and chemistry of each protein has been developed and fine-tuned over billions of years of evolutionary history. We start this chapter by considering how the location of each amino acid in the long string of amino acids that forms a protein determines its three-dimensional shape. We will then use this understanding of protein structure at the atomic level to describe how the precise shape of each protein molecule determines its function in a cell.
