Cell- Unit of life: GATE (Biotechnology)

This is the first lesson in Cell Biology. In order to understand how living systems work , one  has to understand how life originated , developed and diversified over 4.5 billion years of Earth's history. I have given a brief introduction about the origin of life by comparing it with the mythological studies for better understanding. I have talked about some important theories in origin of life, though there were many theories proposed in this topic. These are  vital theories in this lesson from the examination point of view.

Cell Biology - Origin of Life

In this lesson , I have given a brief introduction about the atomic structure and subatomic components which influence biological processes. I have explained about the primary source of energy - SUN , different forms of energy and an overview about Metabolic reactions.

Atomic Basis of Life

In this lesson , I have given an introduction about Biomolecules and the elements essential for life , however , this is just the outline of biomolecules . In the biomolecules part 2 lesson , I will be explaining about the macromolecules in detail.
PS : The marker isn't matching with my vocals , it's slow .
Sorry for the inconvenience.

Biomolecules: Part 1

In this lesson , I have talked about the classification of biomolecules and the significance of 4 vital macromolecules namely proteins , carbohydrates , lipids and nucleic acids.

Biomolecules: Part 2

In this lesson , I have explained about the biological membranes , ion transport and bulk transportation in detail.
PS : The highliter isn't matching with the vocals due to some technical issues .
Sorry for the inconvenience.

Biological Membranes

In this lesson , I have talked briefly about the evolutionary tree of life, classification of prokaryotic organisms and general structure of prokaryotic cells.

Prokaryotic cells

In this lesson , I have talked about Eukaryotic cells and explained in detail about some eukaryotic organelles. In my next lesson, I will talk about the remaining organelles.

Eukaryotic cells part 1

This lesson is the continuation of eukaryotic cell organelles. I have discussed about the remaining organelles in detail and I also represented a flowchart showing heirarchy in the functional organisation of living organisms.

Eukaryotic cells part 2

In this video , I have discussed about the MCQs which are likely possible to come in the medical entrance examination and the questions I have discussed here is related to the topics I have taught in my lessons till now.

MCQs (part 1)

In this video , I have discussed few MCQs which are important in the medical entrance examination point of view  and the questions I have discussed here , is related to the topics I talked about in my previous lessons.

MCQs (part 2)

Cell signalling

Molecular mechanism of signal transduction

Cell signalling part 2 (mechanism of signal transduction)

Cell signalling part 3 (Extracellular communication)

Cell signalling part 4 (transmitters and receptors)

This lesson gives a brief information about Feedback control of hormones , role of peptide hormones, growth factors & neurohormones.

Peptide hormones and growth factors

This lesson describes about the response to specific combinations of extracellular signal and Receptors / Signalling pathways.

Receptors and signalling pathways

This lesson briefly explains about the Ion-channel linked receptors and their types.

Ion-channel linked receptors

This lesson explains about GPCR (G-protein coupled receptors) , this is the most important type of cell surface receptors.

GPCR (G-protein coupled receptors)

Enzyme-linked receptors (protein tyrosine kinases)

Serine/threonine kinases & nuclear receptors

Serine/threonine kinases

This lesson explains briefly about the eukaryotic cell cycle , mitosis , chromosomal disjunction , mitotic spindle apparatus and cytoskeletal proteins.

Cell Division : Propagation of Genetic Information

This lesson describes about the different stages of mitosis , cytokinesis and a bit information about regulation of cell division.
