Proteins

Proteins are the macromolecules coded in our DNA that function as a biocatalyst and build our body. Apart from Biological knowledge, there are spectacular concepts in the field of proteins. How does a protein produce a function, how do they interact, how did they evolve and how do protein mutations cause disease.

What organelles folds proteins?

Of a class called chaperons. Two types. Small proteins that meet the polypeptide as it come out of the ribosome. These are called chaperons. A large barrel like structure, with lid, that corrects the tougher protein folding problems. These are called chaperonins.

What is the main function of proteins?

Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.

Your body uses the protein you eat to make lots of specialized protein molecules that have specific jobs. For instance, your body uses protein to make hemoglobin, the part of red blood cells that carries oxygen to every part of your body. Other proteins are used to build cardiac muscle. What's that? Your heart! In fact, whether you're running or just hanging out, protein is doing important work like moving your legs, moving your lungs, and protecting you from disease

What does NaCl do during protein extraction?

In solution, NaCl can split into Na+ and Cl- ions. These ions are indeed needed to stabilise the hydrophilic residues of the protein molecule that are exposed on the surface.

So NaCl is a stabilising agent in various protocols even in the extraction, but it does not has any role in lysing the cells or neutralising other biomolecules.

What are structural proteins?

Structural proteins are fibrous proteins. The most familiar of the fibrous proteins are the keratins. This forms skin, fur, hair, nails, hooves, horns, beaks and feathers. Other structural proteins are the actin and myosin proteins of muscle tissue, tendons and ligaments.
Structural proteins are proteins that build up our tissues or body. actin, myosin, clotting factors are some of the structural proteins. They give up a shape and rigidity to our cells or tissues and ultimately to our body (muscle).

Examples of functional proteins?

Functional proteins carry out a function in the body unlike structual proteins which produce structures (eg bones and muscles). An example of a functional protein is antibodies as they carry out the function of fighting off bacteria and virus'. Another example is hemoglobin which transports oxygen around the body.

What organelle makes proteins?

ribosomes


Proteins are made in ribosomes. mRNA transcribed from DNA carries the message of protein sequences. In ribosome mRNA interact with tRNAs to form polypeptides from amino acids.
ribosomes translate proteins from amino acids. The message needed for the synthesis is coded in mRNA. mRNA is transcribed from DNA for this and exported to cytosol.

How are proteins made?

Proteins are made by protein synthesis in the cytoplasm. DNA is responsible for coding the information that will make proteins. DNA transcribe mRNA, transport it from nucleus. Ribosome and tRNA in cytosol synthesis proteins as per the message coded in the mRNA.

How are proteins digested?

Proteins are digested by proteasees (enzymes) in the digestive system. Trypsin, peps, chymotrypsis are the proteases of stomach that start digesting proteins in to peptides. Enteropeptidases further digest them to small peptides and finally amino acids.

What do proteins do?

Proteins serve in two major roles. Some of them make up part of the structure of our bodies. Others are enzymes. An enzyme is a protein that works like a tool. It helps a particular chemical reaction take place.
Protein helps in building and repairing the body tissues. it also produces enzymes and hormones, helps in building up stamina.
They do most of the work in cells and provide structure, function, and regulation to the cell.

What are transport proteins?

In one method, transport proteins in the cell membrane "pick up" molecules outside the cell and carry them in, using energy. Transport proteins also carry molecules out of cells in a similar way.

Are all enzymes proteins?

Most, but not allPrior to 1967, the assumption was that all biological catalysts were proteins. But an investigation into RNA splicing showed that there was no protein involved in cutting introns out of hnRNA (pre-RNA). In fact, the molecule responsible for breaking the phosphodiester bonds was snRNA (small nuclear RNA). snRNA and associated proteins are together called snRNPs (snurps), which gather in a spliceosome. The hnRNA is fed through the spliceosome and the snRNA breaks and reattaches bonds. From this point on, it was clear that ribonucleic acids could act as enzymes, and proteins were not alone. Enzymes that are ribonucleic acids are referred to as ribozymes.

What organelle synthesizes protein in a cell?

The ribosomes do the actual translation of mRNA into proteins. These are either free ribosomes or those located on the RER (rough endoplasmic reticulum).
Ribosomes: Ribosomes are packets of RNA and protein that play a crucial role in both prokaryotic and eukaryotic cells. They are the site of protein synthesis. Each ribosome comprises two parts, a large subunit and a small subunit. Messenger RNA from the cell nucleus is moved systematically along the ribosome where transfer RNA adds individual amino acid molecules to the lengthening protein chain.
ribosomes in the cells make proteins
ribosomes in the cells make proteins
The organelle or bodies responsible for protein production is Ribosomes. They are also termed of protein factories. mRNA molecule that codes the sequence of protein will bind to ribosome for protein production.

What is an amino acid?

Is an organic compound that contains both a basic amino group and a carboxyl group. The alpha amino acids, in which the amino group is attached to the alpha carbon, are the building blocks (or monomers) of peptides and proteins. The amimno acids are commonly classified either as: a) neutral, basic, or acidic, or as b) nonpolar, polar and uncharged, or polar and charged, according to their structures.

Where are proteins made in a cell?

Responding the original question: "What is responsible for protein synthesis?", we can consider 3 participants in what it's called "Translation process" or biosynthesis of peptides (proteins): 1) the mRNA molecule to be translated; 2) the tRNAs carrying an amino acid molecule to be added to the growing peptide molecule; and 3) the ribosome, the structure where the translation is taken place.
