Describe how organelles work together to make and secrete a protein

Insulin is a peptide hormone that is produced by beta cells of the islets of langerhans present in pancreas, and it regulates centrally the carbohydrate and fat metabolism in body.

Organelles Working Together Organelles Working Together In order for cells to function and survive, their organelles work together to carry out specific tasks and perform specific roles. Each organelle has its own role that contributes to the survival of the cell. This is called the Division of Labour.

The Cytoskeleton

The Cytoskeleton The Cytoskeleton of a cell consists of a network of protein fibres that give the cell stability and allow it to move. In Eukaryotic Cells, the proteins are arranged as microfilaments small solid strands and microtubules very small protein cylinders.

The Cytoskeleton provides an internal framework for the cell, which preserves its shape and holds its organelles in position. Part of the Cytoskeleton, fibres called Actin Filaments, are similar to the fibres found in muscle cells and they are able to move against each other.

They are responsible for the movement of some of the organelles and also the movement and change in shape of White Blood Cells. These are made of a protein called Tubulin. Proteins present on some Microtubules, called Microtubule Motors, move organelles, and other cellular content, along the fibres.

This is the mechanism for the transport of vesicles from the Rough Endoplasmic Reticulum to the Golgi Apparatus and the movement of Chromosomes during Mitosis. This is done by the organelles Undulipodia, Cilia, and Flagella.

In Eukaryotic Cells, Undulipodia sometimes incorrectly called Flagella, which are actually only present in Prokaryotic Cells and Cilia are responsible for this movement. They are both structurally similar; they hair-like structures composed of an outer membrane bounding a ring of nine pairs of Microtubules with a single pair in the centre.

Undulipodia are longer than Cilia and usually occur in ones and twos, whereas cilia are often found in large numbers.

A sperm cell moves because it has a long tail. This is an Undulipodium. Cilia are responsible for the movement of mucus past ciliated epithelial cells. Because they are attached to the base, this causes the structure to bend.

They are made of Flagellin, a spiral of protein that attaches to a disk at the base. When this rotates, using energy from ATP, the Flagellum spins, propelling the cell. The instructions to create a particular protein are found in a Gene in the DNA of a cell. This is called Transcription.

What is a cell

The molecule then leaves the nucleus through a Nuclear Pore. There the sequence of Amino Acids is read and the instructions are Translated to a Polypeptide Chain. The next stage is called Post Translational Modification.Protein (Solved) November 10, Describe how antibody is produced, organelles working together to make and secrete antibody, structure of the cell membrane and transportation of various substances across the membrane involved .
