An enzyme citrate synthase in the Krebs cycle is inhibited by ATP What type of inhibition would this be?
Citrate synthase is inhibited by ATP. Obviously, the Krebs cycle produces ATP. This is the first step and one of the major regulatory steps in the pathway. If the cell has plenty of ATP, then it wouldn't need to keep making it, thus the pathway needs to be shut off. ATP inhibits the enzyme to shut off the pathway. This is an example of feedback inhibition (you can also call it negative inhibition or even product inhibition). Feedback inhibition is when the products of a certain biochemical pathway inhibit earlier enzymes, shutting down the pathway.
What is the process called when urea is formed?
It's called the Bosch-Meiser urea process. See https://en.wikipedia.org/wiki/Urea
What is The percentage of nitrogen in urea?
Urea is typically 45-46% nitrogen.
How is competitive inhibition different from non competitive inhibition?
Competitive Inhibition is a substance that binds to the active site in place of the substance while Non-competitive Inhibition is a substance that binds to a location remote from the active site. (:
What are some differences and or similarities in the type of inhibition caused by heat acid or base and heavy metal ions on enzyme activity?
Heat, acid, and base can denature enzymes by disrupting their structure, leading to reversible inhibition. Heavy metal ions can bind to specific amino acid residues on enzyme active sites, causing irreversible inhibition. Both types of inhibition can decrease enzyme activity, although heavy metal ions typically have longer-lasting effects due to the irreversible nature of their inhibition.
Is allosteric inhibition competitive or noncompetitive?
Allosteric inhibition is a type of noncompetitive inhibition.
What is turnover number of invertase from yeast?
MW of the invertase= 270,000
What is the normal substrate for invertase?
The normal substrate for invertase is sucrose. Invertase is an enzyme that catalyzes the hydrolysis of sucrose into its component sugars, glucose, and fructose.
What is the industrial uses of invertase enzyme?
invertase is used by industries to make the inside of chocolates runny. invertase transforms sucrose in glucose and fructose that is less concistent.
What is the molecular weight for invertase?
For yeast invertase, the cytoplasmic form is 135kDa. The excreted form is 270kDa due to heavy glycosylation
What is the enzyme that bees use to make honey?
Invertase
What is The enzyme which converts glucose into ethyl alcohol is?
Invertase
What effect would a higher pH have on the temperatures optimum for invertase?
The temperature optimum can be affected by pH if the pH chosen for a particular experiment deviates from the pH optimum for invertase
How do you get the liquid inside of the chocolate covered cherries?
Among the ingredients added (such as sugar) is an enzyme called invertase. The invertase reacts and is what aids in the cordial process, creating the liquid.
What has the author Hartwell Henry Fassnacht written?
Hartwell Henry Fassnacht has written: 'A study of some properties of yeast invertase activity ..' -- subject(s): Invertase, Yeast
What is the type of enzyme inhibition in which the Km changes but the Vmax does not?
Non-competitive inhibition. This type of inhibition occurs when the inhibitor binds to a site on the enzyme that is different from the active site, causing a conformational change in the enzyme and affecting its ability to bind substrate. The inhibitor can bind to both the free enzyme and the enzyme-substrate complex with equal affinity.
What is the relationship between uncompetitive inhibition and the Michaelis constant (Km) in enzyme kinetics?
In uncompetitive inhibition, the inhibitor binds to the enzyme-substrate complex, not the free enzyme. This type of inhibition does not affect the Michaelis constant (Km) but decreases the maximum reaction rate (Vmax) of the enzyme.
