A rate-limiting enzyme is an enzyme that catalyzes a crucial step in a metabolic pathway and determines the overall rate of that pathway. It usually operates at a slower pace compared to other enzymes in the same pathway, making it the bottleneck for the flow of metabolites. By regulating the activity of this enzyme, cells can control the production of various end products, ensuring metabolic balance and efficiency. Examples include HMG-CoA reductase in cholesterol synthesis and phosphofructokinase in glycolysis.

What switchs on enzyme activity while what can switch off or reduce enzyme activity?
Enzyme activators like cofactors or substrates can switch on enzyme activity by binding to the enzyme and promoting its function. Conversely, inhibitors can switch off or reduce enzyme activity by binding to the enzyme and preventing its normal function.
What kind of molecule is an enzyme-?
The type of molecule that is an enzyme is a protein molecule.
A protein catalyst is known as an?
Enzyme.
What is the name of the enzyme that activates another enzyme?
The enzyme that activates another enzyme is called a kinase. Kinases add phosphate groups to proteins, a process known as phosphorylation, which can activate or deactivate the target enzyme.
What was the result of mixing the boiled enzyme with milk?
Once you boil the enzyme, it will be inactivated. Milk will have no effects of the enzyme.
The binding together of an enzyme and a substrate forms a what?
enzyme-substrate complex
What to enzymes do in an enzyme-substrate?
in an enzyme-substrate complex, the enzyme acts on the substrate .
Does enzyme has proteins?
An enzyme is a protein
How effective is enzyme replacement therapy in treating enzyme deficiencies?
Enzyme replacement therapy is generally effective in treating enzyme deficiencies by providing the missing enzyme to the body. It can help improve symptoms and quality of life for patients with enzyme deficiencies.
What is an angiotensin converting enzyme?
An angiotensin converting enzyme is an enzyme which catalyzes the creation of angiotensin.
What enzyme is responsible for fat digestion?
the lipase enzyme :)
What is the active site for an enzyme?
The place where the substrate and the enzyme meet to allow the enzyme to function.
What is it called when and enzyme and substrate come together?
When an enzyme and substrate come together, it is called the enzyme-substrate complex. This complex is a temporary intermediate state in which the enzyme binds to the substrate to catalyze a chemical reaction.
What switchs on enzyme activity while what can switch off or reduce enzyme activity?
Enzyme activators like cofactors or substrates can switch on enzyme activity by binding to the enzyme and promoting its function. Conversely, inhibitors can switch off or reduce enzyme activity by binding to the enzyme and preventing its normal function.
What enzyme speeds up a chemical reaction is known as?
All enzyme's are catalysts for certain chemical reactions. Each enzyme will only work with a certain substrate one analogy being that the enzyme is a key and the substrate is a keyhole, and each enzyme has a unique enzyme.
Is fructase an enzyme?
There is no enzyme by the name "fructase." However, an enzyme called fructosidase catalyzes the hydrolysis of fructose-containing compounds.
If z is a substrate for either enzyme a or enzyme b what is the michaelis constant of enzyme a?
