Animal Tissue
As mentioned earlier, cells are the smallest units of life. In complex organisms, cells group together with one another based on similar structure and function to form tissues. Tissues provide the numerous functions of organs necessary to maintain biological life. This lab exercise seeks to introduce the various tissues found in the human body and…
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…
COENZYMES
Enzymes may be simple proteins or complex enzymes. A complex enzyme contains a non-protein part, called a prosthetic group (co-enzymes). Coenzymes are heat stable low molecular weight organic compound. The combined form of protein and the co-enzyme are called as holo-enzyme. The heat labile or unstable part of the holo-enzyme is called as apo-enzyme. The…
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,…
Biological Classification
Biological Classification: Understanding the Diversity of Life In the vast tapestry of life that envelops our planet, organisms of all shapes, sizes, and functions coexist. From the towering trees of the rainforests to the microscopic bacteria hidden in the soil, every living entity has a place and role in the intricate web of life. This…
Genetics
Genetics: Unveiling Life’s Blueprint In the realm of genetics, we dive into the complex domains of genes, heredity, and trait inheritance. This captivating field untangles the intricacies of life’s diversity and continuity. It unveils aspects ranging from eye color to susceptibility to diseases. Genes and Heredity: Genes, those DNA segments, house the instructions steering growth,…
WHAT IS CELL?
A cell is the basic structural, functional, and biological unit of all living organisms. It is the smallest unit of life and serves as the building block of all living things. Cells are incredibly diverse in terms of their structure and function, yet they all share common characteristics that define them as cells. Here are…
