How does malonate inhibit NADH?
Malonate inhibits NADH by competing with NAD+ for binding to the active site of enzyme NADH dehydrogenase within the electron transport chain. This competition prevents NADH from donating electrons to the enzyme, disrupting the flow of electrons and inhibiting ATP production.
What are anti enzymes?
Anti enzymes or enzyme inhibitors, are substances which inhibit counteracts the action of an enzyme.
Which method of enzyme control is when the products of a reaction inhibit the working of an enzyme by binding to the enzyme?
The method of enzyme control where the products of a reaction inhibit the enzyme by binding to it is known as feedback inhibition. In this process, the end product of a metabolic pathway binds to an enzyme involved in the pathway, reducing its activity and preventing the overproduction of the product. This regulatory mechanism helps maintain homeostasis and balance within the cell.
What is a substrate effector?
A substrate effector is a molecule that can bind to an enzyme's substrate and either enhance or inhibit the enzyme's activity. This can influence the rate of the enzyme-catalyzed reaction.
Which protein blocks the active site?
In enzymatic reactions, competitive inhibitors are proteins or molecules that block the active site of an enzyme, preventing substrate binding. An example of such a protein is the competitive inhibitor of the enzyme dihydrofolate reductase, which can be used in cancer treatment. These inhibitors mimic the substrate's shape, allowing them to fit into the active site and inhibit the enzyme's activity.
How fructose-1-phosphate inhibit gluconeogenesis?
The fructose-1-phosphate inhibits gluconeogenesis through the enzyme aldolase.
Are celecoxib and Ibuprofen both COX 2 inhibitors?
celecoxib is a preferential COX 2 inhibitor,it selectively inhibit the COX2 nzyme with out intefering with th COX 1 enzyme.ibuprofen inhibits both enzyme celecoxib is a preferential COX 2 inhibitor,it selectively inhibit the COX2 nzyme with out intefering with th COX 1 enzyme.ibuprofen inhibits both enzyme
What antibiotics inhibit RNA synthesis?
Rifampin is an antibiotic that inhibits RNA synthesis by binding to the bacterial RNA polymerase enzyme, thus preventing transcription.
What is the mechanism of action of salicylamide in inhibiting the enzyme N-acetylglucosaminidase (NAI)?
Salicylamide inhibits the enzyme N-acetylglucosaminidase (NAI) by binding to the active site of the enzyme and blocking its function, thereby preventing the enzyme from carrying out its normal biochemical reactions.
Does the Calvin cycle occur only in the dark?
It cannot occur in the dark. It contains an enzyme called rubisco which is a light-activated enzyme. Also the Calvin cycle uses the chemical energy produced in the light reactions, and the light reactions need sunlight energy in order to produce the energy needed in the Calvin cycle. Hope that helps :)
What happens in a metabolic pathway?

Does lipase speed up or inhibit?
Lipase is an enzyme (catalyst) so it speeds up reactions (in this case the breakdown of fats into fatty acids and glycerol).
What enzyme is necessary for the dark reactions?
The enzyme necessary for the dark reactions, also known as the Calvin cycle, is called ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). It is responsible for fixing carbon dioxide from the atmosphere into a stable organic molecule during photosynthesis.
What is the mode of action for sulfisoxazole?
inhibits enzyme activity
