What is the the structural level when two protein chains combine to form an active protein the structural level is?
The structural level when two protein chains combine to form an active protein is called the quaternary structure. This level of protein organization involves the assembly of multiple polypeptide chains, known as subunits, which can be identical or different. The interactions between these subunits are crucial for the protein's functionality and stability. Examples include hemoglobin and immunoglobulins, which rely on their quaternary structure for biological activity.

When two or more polypeptides combine to form a complex structure is called?
This process is called protein quaternary structure, where multiple polypeptide subunits come together to form a functional protein complex. The quaternary structure involves the interaction and binding of individual polypeptide chains to create a biologically active protein. This higher level of organization is essential for the proper function of many proteins in the body.
What name is given to the building blocks that make up protein as small units that combine together to make up long chains?
Amino acids are the building blocks that make up proteins. These small units combine together in long chains to form proteins, which carry out various functions in the body.
What are examples of quaternary structure?
Quaternary structure refers to the assembly of multiple polypeptide chains into a functional protein complex. Examples include hemoglobin, which consists of four subunits that work together to transport oxygen in the blood, and collagen, a structural protein made up of three intertwined chains. Another example is immunoglobulins (antibodies), which are composed of multiple polypeptide chains that form a Y-shaped structure essential for immune response.
What is an example of a quaternary protein?
An example of a quaternary protein is hemoglobin, the protein responsible for transporting oxygen in the blood. Hemoglobin is composed of four polypeptide chains—two alpha and two beta chains—each containing a heme group that binds to oxygen. The quaternary structure allows for cooperative binding, meaning the binding of oxygen to one subunit increases the affinity of the remaining subunits for oxygen. This structural arrangement is crucial for efficient oxygen delivery in the body.
What are small bodies that serve as the site of protein synthesis in cells called?
The small bodies (sometimes called organelles) where proteins are synthesized are ribosomes.At a ribosome, amino acids are assembled into chains called polypeptides.Strictly, the protein is not synthesized at the ribosome, although people often talk that way. This is because what leaves the ribosome is the completed polypeptide chain, which then has to coil, fold, and maybe even combine with one or more other polypeptide chains to form the functional molecule that is the protein.

How do disulfide bonds contribute to the structural integrity of keratin proteins?
Disulfide bonds in keratin proteins help to strengthen and stabilize the protein structure by forming cross-links between different protein chains. This contributes to the overall structural integrity of keratin, making it more resistant to breaking or damage.
What name is given to the building blocks that make up protein as small units that combine together to make up long chains?
Amino acids are the building blocks that make up proteins. These small units combine together in long chains to form proteins, which carry out various functions in the body.
How many polypeptide chains are in a protein?
There is one polypeptide chain in a single protein chain. Polypeptides refer to short protein chains - for example insulin is a 53 amino acid protein and is considered a large polypeptide. Complex multi-component [strand] protein coalescences exist - each uniquely identified component protein strand is called - of course - a subunit: two subunits is called a dimer, three subunits is called a trimer, four is a tetramer etc. A Protein is a string of Pearls {Amino Acids} of which [out of the quadrillion possible] there are ONLY Twenty Biologically Active Types ( with two, sometimes three, more reserved for special occasions ). A common example of a biological multi-strand protein grouping is: 4 strands will combine thusly - 2 strands of one type and 2 strands of another type.
What are chains of amino acids known as?

Where products are formed at the ribosome in a eukaryotic cell?
Polypeptides (chains of amino acids) are formed at ribosomes.These polypeptides subsequently form proteins. Some proteins have a single polypeptide chain; some have more than one. "Protein" is the term for the physiologically active molecule. After leaving the ribosome, each chain must coil and fold into the appropriate shape (and, if necessary, combine with one or more other chains) before the finished protein is formed.

What do gathering chains do on a combine?
Gathering chains on a combine are responsible for collecting and transporting harvested crops from the field to the combine's threshing system. They work by moving the crop from the header, where it is cut, toward the auger, which then distributes it for threshing. The efficiency of gathering chains is crucial for maximizing the combine's performance and ensuring a smooth harvesting process. Properly functioning gathering chains help minimize crop loss and maintain the quality of the harvested material.
