Biochemical Composition and Function of Cell Subscribe
Date: 06. August 2016
In this video lecture, educator introduced the cell as basic structural and functional unit of all living organisms. There are many differences between Eukaryotic and Prokaryotic cell. Plasma membrane, Nucleus, Endoplasmic reticulum, Golgi Complex, Ribosomes, Lysosomes, Peroxisomes. Mitochondria and Cytoskeleton are major organelles of the cell.
Nucleus contains the genetic information of the cell and is concerned with assembly of ribosomes. Ribosomes is responsible for protein synthesis and is composed of R-DNA and proteins. Endoplasmic Reticulum consist of continuous system of interconnecting membrane and is of two types. Golgi Apparatus occupies a characteristic position between nucleus/RER & apical plasma membrane and has several functions in the cell.
Lysosomes are site of intracellular digestion and turnover of cellular components and has different functions in cell. There is a lot of significance of lysosomes clinically. Peroxisome are involved in redox reaction. Mitochondria is enzyme specialized in production of ATP. It is involved in apoptosis; programmed death of cell. Cytoskeleton consists of a large number of proteins and provide internal reinforcement in the cytoplasm.
