Why is the primary structure of a protein important in order to carry out its activity especially if this protein has a catalytic activity?
The primary structure of a protein is the sequence of amino acids in each of its chains. (Some proteins have more than one chain.)
This sequence determines how each chain coils and turns (the secondary structure), and in turn how the whole molecule folds (the tertiary structure). The correct primary structure is essential for the chain to acquire the correct three-dimensional (3-D) shape.
Some amino acids have negative charges on them at physiological pH; some positive. This will influence how different sections of a chain attract and repel one another, and in turn this affects the final shape. Also, one of the amino acids can form sulfur-sulfur cross-links between different parts of the chain. Hydrogen bonding can hold different sections of a chain in position, too, and this will only occur between certain amino acids.
If the protein is an enzyme, it has one or more active sites. Each of these has a shape that is complementary to part of the relevant substrate. So the enzyme must have the correct shape if it is to exhibit catalytic activity.

The level of protein structure primarily involved in determining enzyme activity is the?
The level of protein structure primarily involved in determining enzyme activity is the tertiary structure. This three-dimensional arrangement of the protein allows for the correct positioning of active sites and substrates, facilitating the catalytic function of the enzyme. Changes in the tertiary structure can significantly affect enzyme activity, potentially leading to loss of function.
Can dogs see paranormal activity?
yes, especially when stoned, re: scooby doo.
What is the best activity for senoirs after washing dishes?
volleyball is best after dishes especially for those senior females from ages 70-80
What was France's most important economic activity in North America in the 1600's?
The French established logging and fur trading in this area. It was a profitable business for many years for the French until the Louisiana Purchase.
How did you find activity?
I found the activity engaging and enjoyable, as it provided an opportunity to learn something new and collaborate with others. The structure encouraged participation and creativity, making it a rewarding experience. Overall, it fostered a positive environment that facilitated interaction and skill development.
Do enzymes require ATP for their catalytic activity?
No, enzymes do not require ATP for their catalytic activity.
Why does an enzyme become denatured when heated?
Heat breaks chemical bonds in protein molecule which distorts its structure and catalytic activity .
The level of protein structure primarily involved in determining enzyme activity is the?
The level of protein structure primarily involved in determining enzyme activity is the tertiary structure. This three-dimensional arrangement of the protein allows for the correct positioning of active sites and substrates, facilitating the catalytic function of the enzyme. Changes in the tertiary structure can significantly affect enzyme activity, potentially leading to loss of function.
Does amylase contain both an alpha helix and a beta pleated sheets?
Yes, amylase contains both alpha helices and beta pleated sheets in its secondary structure. These structures are important for maintaining the enzyme's functional conformation and catalytic activity.
What inhibitor has a structure similar to the substrate?
Competitive inhibitors have a structure similar to the substrate, allowing them to bind to the active site of the enzyme and block the substrate from binding. This competition for the active site reduces the enzyme's catalytic activity by preventing the substrate from binding and undergoing a reaction.
What is the structure of enzymes in living cells?
Enzymes are typically structured as proteins with a specific three-dimensional shape that enables them to bind to and interact with specific molecules called substrates. This structure is crucial for the enzyme's function, as it determines the enzyme's catalytic activity and specificity. Additionally, enzymes may have co-factors or co-enzymes that are necessary for their activity.
Important factors in enzyme structure?
Important factors in enzyme structure include the amino acid sequence, which determines the enzyme's overall shape and catalytic function, as well as the presence of co-factors or co-enzymes that are required for activity. The active site of the enzyme is crucial for binding substrates and facilitating chemical reactions. Additionally, the tertiary and quaternary structures of enzymes play a key role in their stability and specificity.
Are especially important because they are involved in a variety of processes such as cell signaling immune response and enzyme activity.?

What is a building block for catalase?
The building block for catalase is a protein molecule made up of amino acids. Each amino acid is connected to form a chain that folds into a specific structure, which is critical for the catalytic activity of the enzyme.
Term describes the alteration of an enzyme's structure?
Enzyme denaturation refers to the alteration of an enzyme's structure, leading to loss of its catalytic activity. This can be induced by factors such as temperature, pH, or chemicals, which disrupt the enzyme's active site and 3D shape. Denaturation usually renders the enzyme nonfunctional.
Why its structure of a molecular important to its function?
The structure of a molecule is crucial to its function because it determines how the molecule interacts with other molecules and its environment. For example, the specific arrangement of atoms can influence a molecule's shape, charge distribution, and reactivity, which in turn affects its ability to bind to receptors, catalyze reactions, or participate in biological processes. In proteins, the three-dimensional structure dictates its role in cellular functions, while in enzymes, the active site configuration is vital for substrate binding and catalytic activity. Thus, any alteration in structure can lead to changes in function, impacting biological systems.
A noncompetitive inhibitor has a structure that?
A noncompetitive inhibitor has a structure that does not resemble the substrate structure. A compound that binds to the surface of an enzyme, and changes its shape so that a substrate cannot enter the active site is called a noncompetitive inhibitor.
