What is proteins subuit?
Proteins are produced as polymer of amino acid chains. They gain secondary structure elements such as alpha helix, beta sheet during folding and for their three dimensional structure. Some proteins such as Hemoglobin make quaternary structure where they form the final structure with four different subunits of two different proteins interacting each other.
Do cells make proteins on small structures called amino acids?
The right question would be, "Do cells make proteins FROM small structures called amino acids?" The short answer is, yes. If your interested in how look up the Hierarchy of Protein Structures. Specifically: Primary Structure ie. the amino acid sequence Secondary Structure ie repeating folding patterns (which help determine function.) Tertiary Structure ie. many folds and patters create a 3-D shape. For some proteins this is the final structure to a functional protein (such as ribonuclease). Quaternary Structure ie. Most functional proteins are comprised of two or more polypeptides that each adopt a Tertiary Structure (see above) and then assemble with each other. When proteins consist of more than one polypeptide chain, they are said to have Quarternary Structure.
Which structure in eukaryotic cell sorts and trasports proteins?
The Golgi apparatus, or Golgi body, is where proteins and lipids are sorted and packed. The Golgi apparatus has different vesicles that are attached to its edges. One of the vesicles is called the transport vesicle which transports the processed proteins and lipids to their final destination.
What modifies proteins and shuttles them between organelles?
The process of protein modification and shuttling between organelles is primarily facilitated by molecular machinery known as the endoplasmic reticulum (ER) and Golgi apparatus. The ER modifies proteins through processes like glycosylation, folding, and quality control. After modification, the proteins are then transported in vesicles from the ER to the Golgi apparatus. The Golgi further modifies the proteins and packages them into vesicles for transport to their final destinations within or outside the cell.
What is a single subunit in biochemistry?
In Protein biochemistry some proteins are made of more than one unit of the same molecule (or similar molecules) - i.e. Actin and Myosin (muscle proteins). It is said that their tertiary structure is the individual subunit, however they also have a quaternary strucure which is the structure formed when many subunits link up. A single subunit in this case is then a protein that has formed its final, folded tertiary structure but which is not part of a larger strcuture.

Why is the three dimensional shape of proteins so important?
Proteins are built as chains of amino acids, which then fold into unique three-dimensional shapes. Bonding within protein molecules helps stabilize their structure, and the final folded forms of proteins are well-adapted for their functions.

What is a three dimensional protein that is formed by the interaction of R groups in the primary structure?
This is not in the primary structure, or even from the primary structure. This folding of proteins into the globular final shape by the bonding interaction of R groups is called the tertiary phase of protein synthesis. ( tertiary means three )

What are final product of protein?
Proteins are the final product. They are made from amino acids.

What are the final products of proteins?
In prokaryotic cells, mRNA is directly produced. In eukaryotic cells, the first product is called the primary transcript.
If proteins were rigid why would they make poor reseptors?
Proteins have a lot of roles in the body. Proteins functioning as receptors have to bind securely to another molecule (usually another protein). Protein structure is defined by the amino acids that make up the protein (primary structure), then two levels of the folding the protein undergoes to get its final shape (ending with tertiary structure). The tertiary structure of protein receptors have to be very complicated to be unique enough to be effective receptors. Therefore, tight binding between the two proteins often requires some amount of rearrangement before the two molecules 'lock' into place. The 'locking' is also done at many locations and doesn't happen all at once. If the molecules were rigid they would have to 'lock' all at once, and spacial rearrangement would be harder.
How long do you have to keep a final divorce decree?
It is important to keep a final divorce decree in a safe place. A person might need the final divorce decree in the future to make certain modifications or to change their last name.
What makes up the final stage of mRNA?
Ribosomes translate mRNA into proteins.
