Yes, most enzymes are smaller in size compared to their substrates. Enzymes typically have specific active sites where they bind with their substrates to catalyze chemical reactions. This specific interaction allows enzymes to facilitate reactions despite being smaller in size.
What else can I help you with?
What is better more substrates or more enzymes?
Depends on how much substrate the enzyme can process. Most enzymes can process more than one molecule of substrate without denaturing or becoming unusable. However, in the terms of your question. More substrate is better. Too many enzymes would mean the reaction would be cut short, because they would all react the substrate at once. So for a prolonged, efficient reaction more substrate would be proper.
What temperature are most enzymes most effective?
37.5 centigrade. however results are pretty much the same in temperatures between 35 and 40
What happens to the rate of enzyme reaction when you increase the enzyme concentration?
As the enzyme concentration increases, the rate of reaction will increase because there are many more enzymes present to aid break down the substrate. However, a point will be reached when no matter how much enzyme is present, the reaction will not occur any quicker. This is equilibrium. This happens because all the substrate is being broken down by the exact same amount of enzyme, so enzymes will be present which have no substrate to break down.
What digestion process begins in the mouth?
the salivary glands secrete enzymes (particularly salivary amylase or ptyalin) necessary for the initial digestion of starch in the mouth. namely, these are the parotid, submandibular and sublingual glands.
What is lock and key?
Lock and Key is one of the theories behind how enzymes fit together with substrates and act as biological catalysts that speed up a reaction in the body. The enzyme usually allows this to happen at much lower temperatures than normal and whithin the range of the animals body. The lock and key refers to the tight specific fitting of the substrate with the enzyme so that specific enzymes can target specific substrates.
STATE the composition of most enzymes?
Enzymes are made of certain combinations of Amino Acids folded into a certain 3-D shape. Most Amino Acids are composed almost entirely of Hydrogen, Oxygen, Carbon and Nitrogen, though sulphur and some other elements are found in much much smaller amounts.
How enzyme catalyze chemical reaction?
Enzymes lower the activation energy of a reaction (that is, the amount of energy that is needed in order for the reaction to occur).Without an enzyme, a reaction may need so much energy that it is impossible to obtain in a normal biological timespan. With enzymes, reactions require much less energy, so that they can occur hundreds of times a second.Enzymes can achieve this catalysis in many ways - for instance, if a reaction involves two substances combining to form one, the enzyme can bind each substance in a specific site that forces them close together, making the reaction much more likely to occur and requiring much less energy for the substrates to locate and approach one another.
What is better more substrates or more enzymes?
Depends on how much substrate the enzyme can process. Most enzymes can process more than one molecule of substrate without denaturing or becoming unusable. However, in the terms of your question. More substrate is better. Too many enzymes would mean the reaction would be cut short, because they would all react the substrate at once. So for a prolonged, efficient reaction more substrate would be proper.
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.
What is the effect of heat on enzymes?
Heat can denature enzymes, causing them to lose their shape and therefore their function. At low temperatures, heat can increase the rate of enzyme activity, but at high temperatures, enzymes can become inactive due to the disruption of their protein structure.
How do enzymes catalyze a reaction to increase the rate of chemical processes in biological systems?
Enzymes speed up chemical reactions in living organisms by lowering the amount of energy needed for the reaction to occur. They do this by binding to specific molecules, called substrates, and bringing them together in a way that makes it easier for the reaction to happen. This process, called catalysis, allows biological processes to occur much faster than they would without enzymes.
Why do enzymes only work with the specific substrates?
Enzymes act only on a specific substrate due to the active site of the enzymes fits perfectly with the substrate. Like 2 puzzle pieces, they can only go together and not with anything else. Enzymes catalyze or help a reaction take place. They bind substrates and then help position them in order that the chemical reaction between these substrates can take place. If they bound things other than the substrates they would be much less efficient in catalyzing the reactions.
Does the stomach produce the most enzymes?
Your saliva produces enzymes to break down food and your stomach has them too, but I am pretty sure that your stomach doesn't produce as much as your saliva.
What are important factors in enzymes structure?
Enzymes are in general globular proteins and range from just 62 amino acid residues in size, for the monomer of 4-oxalocrotonate tautomerase, to over 2,500 residues in the animal fatty acid synthase. A small number of RNA-based biological catalysts exist, with the most common being the ribosome; these are referred to as either RNA-enzymes or ribozymes. The activities of enzymes are determined by their three-dimensional structure.However, although structure does determine function, predicting a novel enzyme's activity just from its structure is a very difficult problem that has not yet been solved. Most enzymes are much larger than the substrates they act on, and only a small portion of the enzyme (around 2-4 amino acids) is directly involved in catalysis. The region that contains these catalytic residues, binds the substrate, and then carries out the reaction is known as the active site. Enzymes can also contain sites that bind cofactors, which are needed for catalysis. Some enzymes also have binding sites for small molecules, which are often direct or indirect products or substrates of the reaction catalyzed. This binding can serve to increase or decrease the enzyme's activity, providing a means for feedback regulation. Like all proteins, enzymes are long, linear chains of amino acids that fold to produce a three-dimensional product. Each unique amino acid sequence produces a specific structure, which has unique properties. Individual protein chains may sometimes group together to form a protein complex. Most enzymes can be denatured-that is, unfolded and inactivated-by heating or chemical denaturants, which disrupt the three-dimensional structure of the protein. Depending on the enzyme, denaturation may be reversible or irreversible. Structures of enzymes with substrates or substrate analogs during a reaction may be obtained using Time resolved crystallography methods.

What is the effect that enzymes have on certain chemical reactions in living things?
Enzymes lower the activation energy (or free energy of activation for the very scientific) of the chemical reactions they catalyse. The enzymes can make a reaction proceed much more quickly than it otherwise would by astronomical figures, e.g. 109 times! Enzymes don't affect the equilibrium position, but they do affect the rate.
What temperature are most enzymes most effective?
37.5 centigrade. however results are pretty much the same in temperatures between 35 and 40
