Allosteric regulation and feedback loops - Khan Academy
Build on your understanding of the two-step process of enzyme catalysis and the Michaelis-Menten Equation as you uncover how allosteric regulation influences enzymatic activity.
Enzyme regulation (article) | Khan Academy
Allosteric enzymes have unique properties like multiple active sites on different protein subunits. They can be regulated by allosteric inhibitors and activators, which bind to sites other than the …
Enzymes and the active site (article) | Khan Academy
When they bind to the active site of the enzyme, they prevent the enzyme from breaking or creating molecules. Noncompetitive inhibitors, also known as allosteric inhibitors, do not …
Cooperativity and the Hill coefficient (article) | Khan Academy
One of the key mechanisms by which enzymes regulate their activity is allostery, which occurs when the binding of a molecule at one site affects the binding of other molecules at distant sites.
Regulation of cellular respiration (article) | Khan Academy
A number cellular respiration enzymes are controlled by the binding of regulatory molecules at one or more allosteric sites. (An allosteric site is just a regulatory site other than the active site.)
Basics of enzyme kinetics graphs (article) | Khan Academy
Allosteric enzyme s typically have multiple active sites and often display cooperativity, meaning that the binding of a substrate at one active site increases the ability of the other active sites to …
Basics of enzyme kinetics graphs (article) | Khan Academy
Allosteric enzyme s typically have multiple active sites and often display cooperativity, meaning that the binding of a substrate at one active site increases the ability of the other active sites to …
Covalent modifications to enzymes (video) | Khan Academy
Learn about covalent modifications and how they change enzyme behavior. Learn about post-translational modifications like methylation, acetylation, and glycosylation.
Competitive inhibition (video) | Khan Academy
In Allosteric competitive inhibition, the competitor binds somewhere else on the enzyme, changing the shape of the active site temporarily, blocking the substrate from binding because the …
Cooperativity (video) | Enzyme kinetics | Khan Academy
Explore the intriguing world of enzyme kinetics and cooperative binding. Delve into the two-step process of enzyme catalysis, the Michaelis Menten equation, and the effects of increasing …
