What is meant by cell economy?
Why must organisms conserve energy?
and
Why must cellular synthesis--ie. peptide formation--be controlled?

THANKS

Cell economy.... Is style in which all processes of cell are carried out in economical way using optimal amount of energy..!

Organism should conserve energy..... so that it can do another work than eating.... i.e. geting food for now and then energy requirement is not a economical stuff for organisms..... so if they can store or conserve it they wouldnt be require to eat when energy is required and organism can do other works in mean time....!

Protein synthesis shouild under controll...... since over production or under production may cause diorders or even malfunctioning of body.... eg over production of thyroxine T3/T4 causes myxiodema... and under production cause exopthelmic goiter...
