BIOTECHNOLOGY
The word biotechnology has come from two words, bios (meaning biology) and technology (meaning technological application). Thus biotechnology is defined as the industrial application of living organisms and their biological processes such as biochemistry, microbiology, and genetic engineering, in order to make best use of the microorganisms for the benefit of mankind. Biotechnology is applied in…
ORIGIN OF LIFE
The earth was formed about five billion years ago. At that time it was extremely hot. The existence of life in any form at that high temperature was not possible. As such, two questions arise pertaining to life: 1. How did life originate on earth? 2. How did primitive organisms evolve into new forms resulting…
Glycolysis Pathway
Glycolysis is a crucial metabolic pathway found in all living cells, serving as the initial step in the breakdown of glucose to produce energy. This ancient and highly conserved process occurs in the cytoplasm and plays a central role in both aerobic and anaerobic respiration. In this note, we’ll delve into the details of glycolysis,…
