The active site is part of an enzyme where substrates bind and undergo a chemical reaction.

∙ 12y ago
The shape of an enzyme's active site is determined by its amino acid sequence, which folds into a specific three-dimensional conformation. This unique shape allows the enzyme to interact selectively with its specific substrate, forming an enzyme-substrate complex for catalysis to occur. Any alterations to the active site's shape can affect the enzyme's function.

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 is it about enzymes that determines which reaction they catalyse?
The specific structure of an enzyme, including its active site, determines the type of reaction it can catalyze. Enzymes bind to their substrates based on complementary shapes and chemical properties, allowing them to facilitate specific reactions by bringing reactants together in a precise orientation. This specificity is critical for enzymes to function efficiently in biological processes.
Why is the shape of H2O2 important to the enzyme catalase?
The shape of H2O2 is important because enzymes like catalase have specific active sites where the substrate (H2O2) binds and reacts. The shape of H2O2 must fit into the active site of catalase for the enzyme to catalyze the decomposition of H2O2 effectively. If the shape of H2O2 does not match the active site, the enzyme may not work properly.
What do acids and bases do to enzymes?
Acids and bases can denature enzymes by disrupting their shape and changing the active site where substrates bind. This alteration can prevent enzymes from catalyzing reactions effectively. pH changes can also affect the ionization of amino acid side chains, influencing enzyme activity.
What happens to enzymes at a low pH?
At low pH, enzymes can denature, meaning their shape and structure change, impairing their ability to function properly. This alteration in shape can disrupt the enzyme's active site, making it unable to bind to its substrate and catalyze reactions effectively. Ultimately, the enzyme may become inactive.
Does the shape of an enzyme protein determine specificity?
Shape of an enzyme specifically shape of its active site determines enzyme specificity .
What characteristics of enzymes makes them specific for substrate?
shape of their active site make them specific for the substrates
How the genetic codes affects an enzyme function?
The gene sequence determines the codon, which in turn determines the aminoacid, which in turn determines the tridimensional shape on the protein, which in turn determines the shape of the active site, which in turn determines what it'll be catalysing.
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.
Does the active site of an enzyme have a shape that is specfic for its given substrate?
Yes all enzymes have an active site where substance are temporarily bound. All enzymes have shape that may change during catalysis. The active site of an enzyme orients its substrate molecules, thereby promoting interaction of their reactive parts.
Substrate molecules bind to enzymes where?
The bind in the active site.
Why are denatured enzymes not able to break down their substrates?
Denatured refers to the loss of the 'native' active SHAPE of the enzyme - the Active Site included; this also causes the enzymes to lose their functions.
What is the enzymes have an attachment site called the active site for what to join?
Active site.
Why do enzymes have an active site?
The structure of an enzymes and its active site determine which substrates will work for the enzyme. This is called the lock and key method. The active site is the lock and the substrate is the key.
How does an enzymes active site relate to its substrate?
An enzyme's active site is where the substrate binds and undergoes a chemical reaction. The active site has a specific shape that complements the substrate's shape, allowing for a precise fit. This interaction facilitates the enzyme to catalyze the chemical reaction efficiently.
How does an enzymes active site relate to it substrate?
The substrate binds to the active site.
What is the attachment site of enzymes called?
Active site.
