Who does the substrate work on enzyme action?
The substrate is the molecule(s) that an enzyme works on
How does the enzyme subsrate help the enzyme work?
Substrates don't help enzymes to work. Without a substrate, an enzyme would have nothing to work on. A substrate is the substance acted on by an enzyme.
What are the molecules that enzymes act on called?
The molecule upon which an enzyme acts is called the substrate.
Competitive inhibitors and how they work?
Inhibitors are substances that alter the activity of enzymes by combining with them in a way that influence the binding of substrate and/or its turnover number. Many inhibitors are substances that structurally resemble their enzyme's substrate but either do not react or react very slowly compared to substrate.There are two kinds of inhibitors: a) competitive inhibitors (those compete directly with a normal substrate for an enzyme-binding site), and b) uncompetitive inhibitors (these bind directly to the enzyme-substrate complex but not to the free enzyme).
How do enzymes work and what is the role of the enzyme substrate complex?
enzymes are proteins in their tertiary form. They have an active site which, because of the particular order of amino acids and thus specific three-dimensional shape, is unique to that type of enzyme. This means they can only bind and react with a specific substrate. The substrate makes contact with the active site and forms temporary bonds with it, such as ionic interactions, dipole interactions, etc. These bonds can then work to eventually break apart the substrate and the enzyme releases the products.

Would catalase act on chemicals other than hydrogen peroxide?
Catalase is an enzyme and enzymes work best with a specific substrate. The enzyme can work with any substrate just not as efficient .
What are the molecules that enzymes act on called?
The molecule upon which an enzyme acts is called the substrate.
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.
What factors affect enzyme activity?
Temperature - too cold the enzyme will still work but slowly, too hot and the enzyme will become denatured . As temperature increases, the kinetic energy of the molecules increases so they move around more, meaning that there are more collisions between the enzymes and substrate molecules and therefore more reactions. pH - different types of enzymes work best in different pH environments. A change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrate) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the substrate. enzyme and substrate concentration - how many there is of each. Changing the concentrations of enzyme and substrate concentrations will affect the number of collisions between them and therefore the number of reactions. enzyme inhibitors - these are molecules which bind to enzymes, reducing their activity (many drugs are enzyme inhibitors). co-factors - these are chemical compounds which bind to enzymes and which are needed by the enzyme to work on substrate molecules. They are often called helper molecules.

How are substrates like keys and enzymes like locks?
Enzymes have an active site that is specific for a substrate - therefore enzymes only work when the right substrate is present. The surfaces of the enzyme and the substrate fit together - like a lock and key - allowing the enzyme to fulfil its function. The theory of "induced fit" is more widely accepted - it is similar, but the enzyme shape changes to accommodate the substrate.
Why do enzymes usually only work on one substrate (or group of closely related substrates)?
Only certain molecules can fit into the active site of the enzyme.
What should be done in order to keep the rate constant over the entire time course?
add more substrate. The rate of the reaction drops when the enzyme no longer has a maximum number of substrate molecules to interact with. Above the maximum substrate concentration, the rate will not be increased by adding more substrate; the enzyme is already working as fast as it can. An enzyme can catalyze a certain number of reactions per second, and if there is not sufficient substrate present for it to work at its maximum velocity, the rate will decrease. Therefore, to keep the enzyme working at its maximum, you must add more substrate.
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.
Can one enzyme work with more than one?
... substrate? Yes, many enzymes can work on any of a family of related compounds.
