What mechanism is used to finely tune enzyme activity according to the needs of the cel l?
Allosteric regulation is a mechanism commonly used to finely tune enzyme activity. This involves the binding of a molecule at a site other than the active site, leading to a change in enzyme conformation and subsequent modulation of its activity. By responding to changes in the cellular environment, enzymes can maintain proper levels of activity to meet the cell's metabolic demands.
What is found in allosteric enzymatic regulation?
Allosteric enzymatic regulation involves the binding of a molecule at a site other than the active site, leading to a change in enzyme activity. This regulation can enhance or inhibit enzyme activity, depending on the nature of the allosteric molecule and its binding effects.
What is the key to controlling the chemical pathway of the cell?
The key to controlling the chemical pathway of the cell lies in regulating and coordinating the activity of enzymes, which are the key catalysts in these pathways. Enzymes can be activated or inhibited through various mechanisms, such as allosteric regulation, covalent modification, and gene expression control. By manipulating these regulatory mechanisms, the cell can finely tune and adjust its chemical pathways to meet its metabolic needs.
Which aspect of lac operon regulation is an example of post-translational control?
The addition of a lactose molecule to the Lac repressor protein is an example of post-translational control in lac operon regulation. This modification prevents the Lac repressor from binding to the operator region, allowing for the transcription of the genes involved in lactose metabolism.
What statement is characteristic of allosteric effectors?
Allosteric effectors may not resemble the enzyme's substrates.
What mechanism is used to finely tune enzyme activity according to the needs of the cell?
allosteric regulation
What kind of regulation exist for enzymes?
Allosteric regulation and Reversaeble regulation :)
Some enzymatic regulation is allosteric?
yes
True or False 'A change in the primary sequence of a protein can affect allosteric regulation'?
True. A change in the primary sequence of a protein can alter its three-dimensional structure, which in turn can affect the binding of allosteric regulators and thus impact allosteric regulation.
What is Role of allosteric enzyme in regulation of purine synthesis?
if the purine synthesis is excess then extra product will bind to the allosteric site then feed back inhibition occurs
Does Allosteric regulation depends on inhibitors binding to the active site of enzymes?
No, allosteric regulation involves molecules binding to a site other than the active site (allosteric site) to either activate or inhibit enzyme activity. This type of regulation can involve activators or inhibitors that induce conformational changes in the enzyme, affecting its activity.
How do allosteric regulation and competitive inhibition compare?
Allosteric regulation involves a regulator molecule binding to a site other than the active site to change enzyme activity. Competitive inhibition involves a molecule blocking the active site to prevent substrate binding. Both can regulate enzyme activity, but allosteric regulation is noncompetitive and can have either an activating or inhibitory effect, whereas competitive inhibition only inhibits enzyme activity.
Some enzymatic regulation is allosteric In such cases which of the following would usually be found?
In allosteric enzyme regulation, the regulator molecule binds to a site other than the active site, called the allosteric site. This binding alters the enzyme's activity by inducing a conformational change in the enzyme structure. This can either activate or inhibit the enzyme's function, depending on the nature of the allosteric regulator.

What part of ATP makes it useful to the cell?
it is regulated by the allosteric inhibitors
How are proteins important to a cell?
They do most of the work in cells and provide structure, function, and regulation to the cell.
Distinguish between allosteric activation and cooperativity?
cooperativity is an interaction of the subunits of a protein whereby a conformational change in one subunit is transmitted to all others. allosteric regulation is when an activation molecule bonds to an active site where the subunits join.
