Proteins

No; splenda contains sugars, which are carbohydrates.

Yes, proteins are made up of elements such as carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. These elements are arranged in specific sequences to form the unique structure of each protein, allowing them to perform various biological functions in the body.

Amino acid tyrosine is an aromatic amino acid coded by UAU and UAC in RNA. It is not an essential amino acid as they can synthesized in our body from phenylalanine. Milk poultry, cheese, almonds and peanuts are some example of good source of proteins containing tyrosine.

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.

Enzyme are not producing proteins but they catalyses the steps in proteins synthesis. Proteins are produced in ribosomes by amino acids and RNA molecules such as tRNA and mRNA. Enzyme such as peptidyl synthetase catalyse the prptide bond formation between amino acids.

Yes, prokaryotes can synthesize proteins. They have ribosomes and the necessary machinery to transcribe DNA into mRNA and then translate the mRNA into proteins. The process of protein synthesis in prokaryotes occurs in the cytoplasm.

No, ribosomes do not package proteins. Ribosomes are responsible for synthesizing proteins by translating mRNA sequences into amino acids to form a polypeptide chain. Once proteins are synthesized, they may undergo further processing, folding, and packaging in organelles like the endoplasmic reticulum and the Golgi apparatus.

Proteins are synthesized within the ribosomes, which are a part of the rough endoplasmic reticulum, or RER. The RNA works with the ribosomes during the translation process to synthesize the proteins within the cell.

The bonds between the amino acids are called peptide bonds. You can have up to eight different elements that make up a protein, they are:
Oxygen
Hydrogen
Carbon
Nitrogen
Phosphorus
Copper
Iron ( They're are four iron atoms in every hemoglobin protein )
Sulfur

Integral proteins are membrane proteins that are permanently attached to the membrane phospho lipid bilayer.ATPase enzyme is an example for the integral proteins which make ATP. Peripheral proteins in contrast present on the surface of the membrane.

No phosphorous is an element and cant be a protein. Proteins rather don't have phosphorous primarily in their amino acid or backbone. But after the protein synthesis, they can be phosphorylated (addition of phosphate) to their residues by kinases.

Proteins are necessary because it has variety of functions in the cell. We consume protein rich food to meet the requirement of essential amino acids in our body. Our body synthesizes all the proteins needed for its structural and functional activities.

Peptide bonds connect amino acids. ~

Denaturants such as urea, SDS, guanidium hydrochloridecan denature proteins. Organic solvent such as alcohol can be also used to denature proteins. A combination of reducing agent DTTor beta-mercaptoethaol with heating at 90 degrees for 5 minutes about will completely kill the three dimensional structure of proetin and make it to its primary structure.

This is a rather tricky question. Nascent proteins may be folded right upon the ribosome that makes them - in this case the answer would be the ribosome, or the cytoplasm.

However, most of the folding and post-translational modifications occur in the endoplasmic reticulum and the Golgi-apparatus.

To further complicate the issue, all biological function of proteins hinges on their 3D shapes, so the folding process never actually stops for good - processes such as phosphorylation for activation/inactivation also change the tertiarry/quarternarry structure, and can be considered micro-folding.

Rough endoplasmic reticulum.......

No, DNA does not directly synthesize proteins. DNA contains the genetic information that is transcribed into messenger RNA (mRNA), which is then translated by ribosomes to synthesize proteins. This process is known as protein synthesis or translation.

Not only bacteria, also fungi, algae, plants, animals and human need proteins. Bacteria do carry out metabolic process, reproduction, motility and other life processes, hence they need proteins. In case of human, not all the amino acids can be synthesized by our cell, so we consume protein diet to acquire them.

No proteins contain uracils as nucleotides are not part of the proteins. Uracils present in RNA(but not DNA). Uracil can pair with Adenine with a double hydrogen bond.

No, nucleotides ar

e the building blocks for nucleic acids such as DNA or RNA. The building blocks for proteins are amino acids.

Wheat (Grape-Nuts cereal), dairy products, meat, poultry, nuts, and peanut butter. There is a website that shows the nutritional content of all types of food: http://www.nal.usda.gov/fnic/foodcomp/search/
meats and beans
Meats, eggs, peanut butter, fish, beans, oatmeal

Grapes are not a significant source of protein. They are mainly composed of water, natural sugars, and dietary fiber. If you are looking to increase your protein intake, it is better to consume protein-rich foods such as meat, dairy, legumes, and nuts.

Yes, butter contains trace amounts of proteins, but the main components of butter are fat and water. Butter is not a significant source of protein compared to other foods like meats, eggs, or legumes.

No, centrioles do not make proteins. They are cylindrical structures composed of microtubules and play a role in organizing the microtubules during cell division. Proteins are typically synthesized in ribosomes, not in centrioles.
