Its molecular shape is altered so the substrate cannot fit to its active site
fit into the active site on the enzyme
The substrate fits into the enzyme, much the way a key fits in a lock. Sometimes there are other "modulators" that also fit in the enzyme.
When an enzyme binds to the appropriate substrate, subtle changes in the active site occur. This alteration of the active site is known as an induced fit.Induced fit enhances catalysis, as the enzyme converts substrate to product.Release of the products restores the enzyme to its original form. The enzyme can repeat this reaction over and over, as long as substrate molecules are present.
Enzymes are proteins that have a very specific structure. The region on the surface of an enzyme that is responsible for binding and converting the subtract into the product is called the active site.
The lock and key model means that the substrate must perfectly fit the enzyme, and the enzyme does not change. The induced fit model is different as when the substrate fits together with the enzyme, the enzyme itself will change to either join substrates together or break a substrate down.
a. The substrate can be altered so it is induced to fit into the enzyme's active site. b. The enzyme changes its shape slightly as it binds to the substrate. c. The enzyme is altered so it is induced to fit many different types of substrate. d. Several sites on an enzyme can be induced to act on a substrate.
A change in the shape of an enzyme that allows it to better bind with a substrate is called induced fit. This conformational change occurs when the enzyme interacts with the substrate, forming a more complementary fit that enhances reaction efficiency.
Its molecular shape is altered so the substrate cannot fit to its active site
The rate of the enzyme-controlled reaction will increase until all enzyme active sites are saturated with substrate. After that point, the rate will remain constant as all enzyme molecules are already actively engaged, leading to saturation kinetics.
On one part of an enzyme is an active site (which is what the substrate binds to) that is shaped a certain way, say a triangle. A substrate that's in the shape of a square won't fit onto the triangle/the enzyme - but a substrate that has an indent in the shape of a triangle will. The way an enzyme recognizes its substrate is if it can attach itself to the enzyme's active site.
substrate can fit into, due to complementary shapes and charges. This allows the enzyme to specifically catalyze a particular reaction. Any changes to the active site can impact the enzyme's ability to bind to its substrate and perform its function.
Induced fit refers to the concept that enzymes can change their shape slightly to better accommodate the substrate, leading to a tighter binding and improved specificity. The structural adjustments that occur during induced fit can create a better alignment between the enzyme's active site and the substrate, increasing the likelihood of a successful reaction. This process helps ensure that the enzyme specifically recognizes and binds to its intended substrate, enhancing its catalytic efficiency.
The model you are referring to is the lock-and-key model of enzyme-substrate interaction. This model proposes that enzymes have specific active sites that perfectly fit the substrate, similar to how a lock fits a key. This precise fit allows for the formation of the enzyme-substrate complex and subsequent catalysis of the reaction.

Their Shapes Fit Snugly Together.
The part of the enzyme with a specific shape to bind with a specific substrate is called the active site. This is where the enzyme and substrate interact to form an enzyme-substrate complex, leading to catalysis of the reaction. The specificity of this interaction is crucial for the enzyme to carry out its biological function.
