What is the effect of hydrochloric acid on the enzyme activity?
Denature enzyme activity
How can induced fit influence the specificity of an enzyme?
Induced fit: is a more recent theory which suggests that the substrate attaches to the enzyme in a relatively accurate fit, then the enzyme moulds around it, then continues the chemically complex reaction. Lock and Key Mechanism: As obvious as the name states, the lock and key model is simply the substrate fitting acutely into the enzyme with no adjustments required to the enzyme. K.G. ;)
What is the purpose of GUAIACOL?
Guaicol is used as a substrate for peroxidase activity, when we treat it with enzyme the activity of enzyme increases at a higher rate.
What are the two theories that explain enzyme specificity?
1. Victor Henri's Quantitative Theory of Enzyme Kinetics 2. "Lock and Key" Theory- First introduced by Emil Fischer in 1894
What is enzyme-substrate specificity?
It means that an enzyme will only work on one specific substrate at a time, because no meaningful biochemical activity can occur without their absolute specificity.We are talking about 30,000 bio-enzymatically controlled Biochemical reactions.In the Chem Lab a product yield of 60 percent is a huge achievement.In the Body anything less than a 100 percent yieldwould swiftly result in the Cell being overwhelmed by the useless by-products of these 30,000 biochemical Reactions.
Does the shape of an enzyme protein determine specificity?
Shape of an enzyme specifically shape of its active site determines enzyme specificity .
What causes enzyme specificity?
The enzyme's surface folds are complementary to the substrate's surface folds.
What are the different types of enzyme specificity with examples?
1) absolute specificity 2) Group specificity 3) Linkage specificity 4) Stereochemical specificity
What would be unlikely to contribute to the substrate specificity of an enzyme?
The allosteric site is distinct from the active site, and does not affect the substrate specificity of the enzyme
Why does increase enzymes concentration promote enzyme activity?
Increasing enzyme concentration increases the number of collisions between the enzyme molecules and the substrate molecules. This increases the number of successful collisions and the number of enzyme-substrate complexes. Therefore the reaction rate is increased as well and enzyme activity is promoted.
What is the definition of enzyme specificity?
each enzyme has a specific substrate to which it binds through a definite active site and any other enzyme can not bind to it
The lock and key hypothesis attempts to explain the mechanism of?
enzyme specificity
What property of enzymes does protease not working on lipids show?
Enzyme specificity .
If an enzyme is a protein how might you change the specificity of such an enzyme?
What an enzyme does is based on its shape, therefore you would have to change it on a molecular level in order to alter its job.
Can an enzyme bind to nearly any molecule?
No; enzymes have substrate specificity, which means the substrate has to be a specific shape for the enzyme to bind to it.
What can you do to regain the activity of the enzyme?
The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity
What is the effect of hydrochloric acid on the enzyme activity?
Denature enzyme activity
