Enzymes and the active site (article) | Khan Academy
Enzymes catalyze chemical reactions involving the substrate (s). The substrate is transformed into one or more products, which are then released from the active site.
Enzymes review (article) | Khan Academy
Each type of enzyme typically only reacts with one, or a couple, of substrates. Some enzymes are more specific than others and will only accept one particular substrate.
Enzymes (video) | Cellular energetics | Khan Academy
An enzyme is just a special chemical. This means that it can react and form temporary bonds. The same way sodium and chlorine come together, enzymes and their substrates can come …
Enzyme regulation (article) | Khan Academy
Compartmentalization means that enzymes needed for specific processes can be kept in the places where they act, ensuring they can find their substrates readily, don't damage the cell, …
Enzyme inhibition and kinetics graphs (article) | Khan Academy
This article discusses the specific effects of various enzyme inhibitors on kinetic graphs, highlighting how these visual tools can be used to pinpoint the type of inhibition involved.
Basics of enzyme kinetics graphs (article) | Khan Academy
Enzymes are generally substrate-specific, meaning they typically catalyze reactions on a single substrate, although some enzymes may have broader substrate specificity.
Cooperativity and the Hill coefficient (article) | Khan Academy
This articles reviews positive and negative cooperativity in enzymes and how this is expressed numerically by the Hill coefficient.
Steady states and the Michaelis Menten equation - Khan Academy
Explore how enzymes speed up reactions, the role of substrate concentrations, and the importance of the Michaelis constant. Discover how to score an enzyme's catalytic efficiency …
Induced fit model of enzyme catalysis (video) | Khan Academy
Now since enzymes have unique active sites, we say that enzymes are specific to certain substrates, and by extension certain reactions. But let's dive a little deeper into what happens …
More enzyme types and mechanisms of catalysis (article) - Khan …
This article provides an overview of different classes of enzymes, as well as the mechanisms used by enzymes to lower activation energy and speed up a reaction.
