It is exactly the same as for proteins, because enzymes are a form of protein. They are comprised of a string of amino acids.
The enzyme whose activity decreases in both acidic and basic environments is pepsin. Pepsin is an enzyme found in the stomach that functions optimally at a pH of around 2. In environments that are either too acidic or too basic, the structure of pepsin can be denatured, leading to a decrease in enzymatic activity.
The function of an enzyme is dependent on the shape of the enzyme. The structure and shape determines what the enzyme can do.
pH - denatures the enzyme by altering the charges on the enzyme. This will affect the structure of the enzyme and its ability to function. Heat - will denature the enzyme by breaking its bonds. This will stop the enzyme from being able to bond to a specific substrate molecule. Cold - not enough energy to reach minimum amount of activation energy needed to undergo reaction. The enzyme will not be able to react on the substrate.
If an enzyme is placed in an environment that is too acidic or too basic, its structure can be denatured, which means its active site will change shape and it will no longer be able to catalyze reactions effectively. This will decrease or even stop its enzymatic activity.
Easily Explained thusly: When the key is in the lock the Enzyme has one Structure, and when the key is not in the lock the Enzyme has another Structure. Note that the presence of a key may either activate or deactivate an Enzyme, depending upon the conditions.
They are said to be denatured.Their tritiary structure is lost.
The destruction of the structure of an enzyme is called denaturation. Denaturation can be caused by factors such as heat, pH changes, or chemicals, leading to loss of the enzyme's biological activity.
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.
SQL: Basic 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.

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.
