The active site of an enzyme can change shape due to interactions with the substrate, binding cofactors or inhibitors, changes in pH or temperature, or mutations in the enzyme's structure. These alterations can affect the enzyme's ability to bind to and catalyze reactions with substrates.
aside from pH and temperature,
another factors include:
Concentration of the substrate (less substrate, less activity)
Concentration of the enzyme (less enzyme, less activity)
Presence of Inhibitors
Presence/Concentration of Coenzymes
Rate of Enzyme production (less production, less activity)

Why are denatured enzymes not able to break down their substrates?
Denatured enzymes have lost their specific three-dimensional shape, which is essential for binding to their substrates. Without the correct shape, the enzyme cannot properly interact with the substrate to facilitate the necessary chemical reactions for breaking it down. As a result, denatured enzymes are unable to effectively catalyze the breakdown of their substrates.
A permanent change in the shape of the enzymes active site caused by high temperatures?
This is known as denaturation. High temperatures can disrupt the bonds holding the enzyme's active site in its specific shape, leading to a permanent change in its structure that impairs its function. Once denatured, an enzyme may no longer be able to bind to its substrate effectively.
What characteristics of enzymes makes them specific for substrate?
shape of their active site make them specific for the substrates
What happens when enzymes unwind and change shape?
When enzymes unwind and change shape, it can disrupt their ability to bind to substrates or catalyze chemical reactions effectively. This alteration in shape can result in loss of enzyme function, impacting the biochemical processes they are involved in. It is crucial for enzymes to maintain their proper structure to ensure optimal activity.
Why does destroying the active site by heating the enzyme to a high temparature stop the enzyme from working?
Extremely high or low pH values or heat generally result in complete loss of activity for most enzymes. They lose the shape that they should be in to fit into the active site. They and the active site work as a lock and key. If the key (or the lock) change shape, the mechanism will not work.
What substance takes place in an enzymatic reaction but does not change shape?
Enzymes. Substrates react with the active site of the enzyme and are broken down. Enzymes stay the same throughout the reaction.
Do enzymes change shape after reaction occurs?
no
Does the active site of an enzyme have a shape that is specfic for its given substrate?
Yes, the active site of an enzyme has a specific shape that is complementary to the shape of the substrate it binds to. This allows for precise recognition and binding between the enzyme and its substrate, facilitating the catalytic reaction.

Why must a molecule have a specific shape if it is to be a substrate of an enzyme?
Active sites of enzymes (where the substrates fit in) are substrate specific, and are complementary to the shape of the molecule (substrate). In this way, enzymes can only act on a specific substrate, since that is the only shape that it will accommodate in the active site.
What properties of enzymes give rise to their ability to distinguish one substrates from another?
Enzymes have specific active sites that can only bind to complementary substrates, based on size, shape, and chemical properties. The binding of substrates to the active site induces a conformational change in the enzyme that stabilizes the transition state for the reaction with that particular substrate. Additionally, enzymes may undergo induced fit where the active site reshapes to better accommodate the specific substrate.
What effects does acid have on ezyme?
Acid can denature enzymes by disrupting the hydrogen bonding and changing the shape of the enzyme's active site, which prevents it from effectively binding to its substrate. This can inhibit the enzyme's ability to catalyze reactions and can ultimately lead to a loss of enzyme function.
What refers to the situation in which the binding of a substrate to the enzyme causes a change in the enzymes shape facilitating an enzymes function?
This situation is known as induced fit. When a substrate binds to an enzyme, the enzyme's shape can change to better accommodate the substrate, creating a more optimal environment for the catalytic reaction to occur. This induced fit mechanism helps enzymes to be more specific and efficient in their function.

What is the change in shape of rock due to stress?
Shape of rock also changes because of stress. It causes the rock to change its shape. When a lot of pressure applies it causes the rock to change its shape.
