Centrosome and Golgi Bodies

Golgi Bodies And Centrosome

Golgi bodies


Golgi Bodies


Golgi bodies were discovered by camelo Golgi in 1898.
 These are present in animal and also in plant cells.
 The Golgi bodies are composed of phospholipid and protein, they contain 3 to 20 sacs.
The Golgi apparatus is a collection of membrane enclosed in sacs (cisterns)  that are  stalked like dinner plates. These cisternae are associated with vesicle called Golgi vesicles.

 The Golgi complex is a complex system of interconnected tubules, these tubules are present around Central stocks.
One or more Golgi apparatus are present in all Eukaryotic cells.

 Golgi is directed at proper glycosylation of protein and lipids. There are more than 200 enzymes that function to add remove are modified Sugars from proteins and lipids in the Golgi apparatus. 
The Golgi apparatus in polarized structure with cis and trans sides.
Newly synthesized proteins bud off from the granular endoplasmic reticulum and fuse with the cis side (protein through other vesicle) middle cistern and finally to the cistern on the trans side,from which vesicle branch of into the cytoplasm.

Function

 Golgi Complex are concerned with cell secretion.
Transport the enzyme and protein outside the cell.

Centrosome
Centrosome near the nucleus in the cytoplasm, made up of two centriole. Centrioles are short cylindrical Organelles,that are present at right angle to each other.
Each Centriole is composed of 9 sets of triplet microtubules arranged in a ring.
When cell divides the centriole replicate and move towards the opposite poles.
 Produce gamma tubulin which help in attachment of spindle fibre to the centromere.

 In multinucleated cells a centromere  is present near each nucleus.
These are also called  microtubule organising center.

Neurotransmitters and receptors

Image
Neurotransmitters and receptors Did you know there are billions of neurons—and trillions of synapses—in your amazing brain? ^1 1 start superscript, 1, end superscript  (No wonder you can learn anything, including neurobiology!) Most of your synapses are  chemical synapses , meaning that information is carried by chemical messengers from one neuron to the next. In the article on synapses, we discussed how synaptic transmission works. Here, we’ll focus on  neurotransmitters , the chemical messengers released from neurons at synapses so that they can “talk” to neighboring cells. We’ll also look at the receptor proteins that let the target cell “hear” the message. Neurotransmitters: Conventional and unconventional There are many different kinds of neurotransmitters, and new ones are still being discovered! Over the years, the very idea of what makes something a neurotransmitter has changed and broadened. Because the definition has expanded, some recently discovered n

The Importance of Animal Physiology

The Importance of  Animal Physiology Why is the study of animal physiology important to you and to people in general? Not the least of the reasons is the one we have already emphasized—namely, that a full understanding and appreciation of all the marvels and other phenomena of the animal world depends on an analysis of how animals work. The study of physiology draws us beyond surface impressions into the inner workings of animals, and nearly always this venture is not only a voyage of discovery, but also one of revelation. The study of physiology also has enormous practical applications because physiology is a principal discipline in the understanding of health and disease. The analysis of many human diseases—ranging from aching joints to heart failure—depends on understanding how the “human machine” works. A physician who studies heart disease, for instance, needs to know the forces that make blood flow into the heart chambers between one heartbeat and the next. The physician also

What are chromosomes?

Image
Chromosome Chromosome During cell division the chromatin material change into thread like structure called chromosome. Chromosomes are also called physical basis of hereditary. On the chromosomes small bodies are located call genes. There are thousands of genes are present in an organisms.Genes are the unit of heredity. These genes contain hereditary character which are transfered from one generation to another by the help of chromosomes. Chromosomes were discovered by a biologist waldyer in 1876. After that in  1908 Sutton identified the function of chromosomes,that they take part in the transfer of hereditary characters.      ( Next post will be about Structure of chromosomes)
