Bacteria and Plants: Master Chemists

Bacteria and Plants are master chemists. They synthesize mind boggling variety of chemical compounds like macro molecules like sugars, proteins, lipids and enzymes using simple chemicals present in the medium and soil. Some of them take mineral carbon (CO2) and water and partition it into products of great use e.g. proteins, sugars, lipids and hydrocarbons. As opposed to the their counterparts in the laboratory which can create optimum conditions like high temperature and pressure required for the reactions, they do the same synthesis under the prevailing conditions using enzymes which they synthesize in the first place. Then there are others… Read More »Bacteria and Plants: Master Chemists

The apple might be an emblem of simplicity, but accounting for all the energy needed to produce one is another matter. You have to factor in pesticide production, fertilizer manufacturing, irrigation, harvesting, sorting, and transportation. Electricity and diesel fuel are needed to drive all these steps, and coal mining and oil extraction come with their own energy costs. And that’s just the apple. Here is a list of some items of… Read More »Energy required for creating different types of food
