What statement is characteristic of allosteric effectors?
Allosteric effectors may not resemble the enzyme's substrates.
Is hemoglobin allosteric?
Yes, Hemoglobin (Hb) is allosteric - it is also cooperative, which is a related but separate phenomenon. An allosteric protein has binding sites for effectors that can alter binding of another molecule or substrate. These effectors can be positive or negative. Hemoglobin has many negative effectors, which cause it to release the O2 that it is carrying. These include 2,3, Bisphosphoglycerate, Carbon Dioxide, and H+ (low pH).
When a pathway is subject to allosteric feedback inhibition ...?
an accumulation of effectors slows the pathway.
What is the general features of allosteric regulation using the feedback inhibition?
enzymes situated at key steps in metabolic pathways are modulated by allosteric effectors these effectors are usually produced elsewhere in the pathway effectors may be feed-forward activators or feedback inhibitors kinetics are sigmoid ("S-shaped")
Does the allosteric effect in an enzyme change the enzyme's function?
Yes, the allosteric effect can change an enzyme's function by altering its activity or affinity for its substrate. This modulation is often achieved by a molecule binding to a site on the enzyme other than the active site, causing a conformational change that affects the enzyme's catalytic activity.
What is the difference between an allosteric enzyme and a non-allosteric enzyme?
An allosteric enzyme has multiple binding sites that can be used to modulate its activity through the binding of effectors or ligands, whereas a non-allosteric enzyme typically only has one active site. Allosteric enzymes can exhibit cooperativity, meaning that binding at one site affects binding at another site, while non-allosteric enzymes do not show this behavior.

What are two types of effectors and how does each respond to stimuli?
There are two main types of effectors namely homotropic and heterotropic effectors. Homotropic effectors substrate themselves while the heterotropic effectors produce enzymes to help in various processes in the body.
Is allosteric inhibition competitive or noncompetitive?
Allosteric inhibition is a type of noncompetitive inhibition.
What are the effectors controlled by the autonomic nervous system?
The effectors leading to skeletal muscle.
How allosteric enzymes differ non allosteric?
Allosteric enzymes have an additional regulatory site (allosteric site) distinct from the active site that can bind to specific molecules, affecting enzyme activity. Non-allosteric enzymes lack this additional regulatory site and their activity is primarily controlled by substrate binding to the active site. Allosteric enzymes show sigmoidal kinetics in response to substrate concentration due to cooperativity, while non-allosteric enzymes exhibit hyperbolic kinetics.
What are effectors of the nervous system?
The effectors of the nervous system are muscles and glands. They respond to nervous stimuli.
