What does enzymes functions depend on?
The function of an enzyme is dependent on the shape of the enzyme. The structure and shape determines what the enzyme can do.
Why does the structure of a protein or enzyme determine its function?
Yes.
What happens to an enzyme and structure as it exceeds the typical human body temperature?
The enzyme can denature and will not function because it is no longer in the proper shape.
What determines the enzyme's function?
Its composition and physical structure - this is determined by the DNA/RNA that coded for it.
What is the loss of structure of an enzyme due to the increase in temperature called?
The loss of structure of an enzyme due to increased temperature is called denaturation. This process disrupts the enzyme's active site, leading to a loss of its biological activity and function.

Yes.
Is renin a hormone?
by function is enzyme ... by structure is hormone
What happens to an enzyme and structure as it exceeds the typical human body temperature?

How structures affects function?
The structure is important because each enzyme's shapes allows only certain reactants to bind the enzyme.
What determines the enzyme's function?
Its composition and physical structure - this is determined by the DNA/RNA that coded for it.
Would lowering the pH of the enzyme solution affect the enzyme?
Yes, lowering the pH of the enzyme solution can affect the enzyme's activity. Enzymes have an optimal pH at which they function best, so altering the pH can disrupt the enzyme's structure and function, potentially leading to decreased activity or denaturation.
What is the loss of structure of an enzyme due to the increase in temperature called?
The loss of structure of an enzyme due to increased temperature is called denaturation. This process disrupts the enzyme's active site, leading to a loss of its biological activity and function.
What happens when an enzyme is renatured?
When an enzyme is renatured, it regains its three-dimensional structure and functional properties after being denatured by heat or chemicals. Renaturation allows the enzyme to return to its active form and resume its biological function.
What are the levels of confirmation of an enzyme?
There are four levels of confirmation of an enzyme: primary structure (sequence of amino acids), secondary structure (alpha helix or beta sheet), tertiary structure (overall 3D shape), and quaternary structure (arrangement of multiple subunits). These levels of confirmation are crucial for the enzyme's function and activity.
How does the structure of an enzyme molecule affect its function in biological processes?
The structure of an enzyme molecule is crucial for its function in biological processes. Enzymes have specific shapes that allow them to bind to specific molecules, called substrates, and facilitate chemical reactions. This specificity is due to the precise arrangement of amino acids in the enzyme's active site. Changes in the enzyme's structure can affect its ability to bind to substrates and catalyze reactions, ultimately impacting the efficiency of biological processes.
Give an example of the relationship between structure and function?
One example of the relationship between structure and function is found in enzymes as their function is dependent upon its structure. Enzymes are catalytic proteins that speed up a reaction without being consumed. Their protein structure enables them to recognize their substrates, even among isomers, thus allowing them to catalyze very specific reactions. The interactions between a protein's primary structure, its amino acid sequence, determine its secondary structure of hydrogen bonded alpha and beta pleated sheets. The side chains of the amino acids help determine the next superimposed structure, the tertiary structure and the quaternary structure if the protein has one. A protein's conformation enables it to form an active site whose shape is compatible with that of the substrate. Once the substrate enters the active site, the enzyme's structure is altered as induced fit moves the active site's chemical groups into positions that enhance their ability to catalyze the chemical reaction, thus improving the enzyme's function. An enzyme's structure is so closely correlated to its function that even a slight change in a protein's primary structure can affect its conformation and ability to function. For example, although noncompetitive inhibitors bind to the enzyme away from its active site, they alter the enzyme's conformation so that the active site no longer has the right structure to bind with the substrates, preventing it from functioning correctly.
