That depends on what part of the body (or otherwise) you're talking about. Lots of the body's structure is made from extracellular protein. A common structural extracellular protein in humans is collagen. There's also keratin. You have a number of extracellular proteins in your blood that take part in the blood clotting cascade, for example Factor VIII (which doesn't work properly in haemophiliacs). You may also secrete antibodies into your blood if you get an infection, and they're extracellular proteins too. And that's without looking at all the extracellular proteins that plants, fungi and unicellular organisms can secrete.
What else can I help you with?
Is proteins the major extra cellular anion?
No; the major extracellular anion is chloride.
If a toxin such as a bacterial toxin destroys ribosomes what cellular activity will be affected first?
Protein synthesis will be the cellular activity affected first if ribosomes are destroyed by a toxin. Ribosomes are responsible for translating mRNA into proteins, so their destruction would impair the cell's ability to produce essential proteins for various cellular functions.
How do cells know what proteins to destroy?
Cells determine which proteins to destroy primarily through a process called ubiquitination, where proteins are tagged with a small protein called ubiquitin. This tagging signals to the proteasome, a cellular complex responsible for protein degradation, that the tagged protein should be broken down. Proteins can be marked for destruction due to various factors, including damage, misfolding, or being no longer needed for cellular function. Additionally, regulatory proteins and cellular signaling pathways can influence the ubiquitination process, ensuring that the right proteins are targeted for degradation.
Are enzymes large proteins?
Yes, that is exactly what they are. Large protein machines for cellular metabolic activities.
What cellular organelle contains protein?
proteins are manufactured by ribosomes in close assocition with endoplasmic reticulum. however the proteins are processed in Golgi bodies
What does a protein kinase do in cellular processes?
A protein kinase is an enzyme that adds phosphate groups to proteins, which can change their activity or function in cellular processes.

Is ubiquitin a protein and what role does it play in cellular processes?
Yes, ubiquitin is a small protein that plays a crucial role in cellular processes by tagging other proteins for degradation or modifying their function.
Is kinase a protein?
Yes, a kinase is a type of protein that helps regulate cellular processes by adding phosphate groups to other proteins.

Which cellular organelle is best described as a factory that builds proteins?
Ribosomes are the protein factory makers
What is the function of a protein kinase in cellular signaling pathways?
A protein kinase is an enzyme that adds phosphate groups to proteins, which can activate or deactivate them. In cellular signaling pathways, protein kinases play a crucial role in transmitting signals within the cell by modifying the activity of proteins, ultimately regulating various cellular processes such as growth, metabolism, and response to external stimuli.
What cellular organelle contains protein?
proteins are manufactured by ribosomes in close assocition with endoplasmic reticulum. however the proteins are processed in Golgi bodies
Why is protein degradation important for maintaining cellular function and overall health?
Protein degradation is important for maintaining cellular function and overall health because it helps to remove damaged or misfolded proteins, regulate protein levels, and recycle amino acids for new protein synthesis. This process ensures that cells can function properly, prevent the accumulation of harmful proteins, and maintain a healthy balance of proteins within the cell.
What cellular organelle is composed of protein and RNA and is responsible for the synthesis of soluble proteins?
Ribosomes are the cellular organelles responsible for the synthesis of soluble proteins. They are composed of protein and RNA molecules. Ribosomes can be found either freely in the cytoplasm or attached to the endoplasmic reticulum.
