What is a substrate in biological terms?
Click to flip
A substrate is the molecule upon which an enzyme acts.
Click to flip
How does an enzyme interact with a substrate?
Click to flip
An enzyme binds to a substrate at its active site, forming an enzyme-substrate complex.
Click to flip
What is the 'active site' of an enzyme?
Click to flip
The active site is the specific region of an enzyme where the substrate binds.
Click to flip
What role does substrate concentration play in enzyme activity?
Click to flip
Substrate concentration can increase enzyme activity until a saturation point is reached.
Click to flip
Describe the 'induced fit' model of enzyme action.
Click to flip
In the induced fit model, the enzyme changes shape to fit the substrate better upon binding.
Click to flip
What is the difference between competitive and non-competitive inhibition?
Click to flip
Competitive inhibition occurs when a molecule competes with the substrate for the active site, while non-competitive inhibition involves binding at a different site.
Click to flip
How does temperature affect substrate binding?
Click to flip
Temperature can increase enzyme activity, but if too high, it can denature the enzyme.
Click to flip
What is enzyme specificity?
Click to flip
Enzyme specificity refers to the ability of an enzyme to recognize and bind to a specific substrate.
Click to flip
What are cofactors and their role in substrate binding?
Click to flip
Cofactors are non-protein molecules that assist enzymes in substrate binding and catalysis.
Click to flip
Why is substrate binding important for enzyme catalysis?
Click to flip
Substrate binding to the active site is essential for catalysis as it forms an enzyme-substrate complex.
Click to flip
What is an allosteric site on an enzyme?
Click to flip
An allosteric site is a region of the enzyme where a molecule can bind, influencing enzyme activity.
Click to flip
How does pH affect substrate binding and enzyme activity?
Click to flip
pH affects the ionization state of amino acids at the active site, impacting binding and activity.
Click to flip
What is the lock and key model of enzyme activity?
Click to flip
The lock and key model suggests that the enzyme's active site and the substrate fit together perfectly.
Click to flip
How do inhibitors affect substrate binding?
Click to flip
Inhibitors can prevent substrates from binding by occupying or altering the active site.
Click to flip
What is the enzyme-substrate complex?
Click to flip
It is a transient structure formed when a substrate binds to an enzyme's active site.
