What class of organic molecules is damaged by high temperature?
Enzymes are proteins. They are very important because they catalyse metabolic processes in the body that would not be able to occur without them. Their function is dependant upon their shape. If an enzyme is not the correct shape for the molecules it need to bind to then it will not be able to catalyse the process it is involved in. The shapes (quaternery structure) of enzymes are the result of attractive forces between funtional groups within the protein. These attrative forces are quite weak, and high temperatures within the body will break them and the enzymes will lose their shape (they are de-natured). Once the structure is lost it cannot be reformed again, so the process regulated by any enzyme that has denatured no longer function properly.
Why does the rate of a reaction slow down when a reduced concentration of hydrochloric acid is added to a chemical?
the hydrochloric acid denatures the enzymes (changes their shapes), so they can no longer bind to the substrate and make the reaction occur.
How does the lock and key model of enzymes action explain the highly specific way some enzymes select a substrate?
This refers to the hypothesis proposed by Emil Fischer in 1894 but confirmed until the 20th century. Fischer proposed that the specificity of an enzyme (the lock) for its substrate (the key) arises from their geometrically complementary shapes. More specifically, the noncovalent forces through which substrates and other molecules bind to the enzyme are identical in character to the forces that dictate the conformations of the proteins themselves. Both involve van der Waals, electrostatic, hydrogen bonding, and hydrophobic interactions.A substrate-binding site consists of an interaction or cleft on the surface of an enzyme molecule that is complementary in shape to the surface (geometrical complementarity). Molecules that differ in shape of functional group distribution from the substrate cannot productively bind to the enzyme; that is, they cannot form enzyme-substrate complexes that lead to the formation of products.
What haves definite shapes and definite volumes?
Solids have definite shapes and definite volume.
Which statement best explains why a relatively small difference in the location of a carbonyl or hydroxyl group can lead to dramatic changes in the properties and function of a monosaccharide?
It alters the shape of the molecule. Monosaccharides function by interacting in precise ways with other molecules based on their shapes, so changing the spatial arrangement of functional groups can dramatically alter function.
Why is it important for plants to hold enzymes in the their functional shapes?
There is thing that do the function and perform a vasendectomy on the enzymes so therefore negating guardies
Why is it important for plants to hold enzymes in their fuctional shapes?
so the plants will not die
Enzymes have specific what that determine their function?
Shapes
What determine the shape and function of a protein?
Conformation is what determines a protein's unique set of functional and otherwise shapes.
Do enzymes have three dimensional shapes?
Yes. Enzymes are like little blobs. They are three-dimensional, but microscopic in size.
Enzymes have specific that determine their function?
Enzymes ARE specific for their substrate. For example: lipase breaks down lipids, not sugars.
Are enzymes carbohydrates or lipids or proteins?
The great majority of enzymes are proteins.Proteins are well suited to the job of catalysis, as they can fold into specific three-dimensional shapes that complement the shapes of their substrates.A few enzymes are RNA. For example, the activity of ribosomes depends in part on the catalytic activity of ribosomal RNA (rRNA).
Why will only certain substrate molecules fit into the active site?
It will only bind with the enzymes active site of the shapes are complimentary and enzymes are very specific
Do plants have particular shapes and sizes?
No, all plants grow very differantly.
What do enzymes and substrates look like?
Enzymes and substrates are molecules and look like any other molecules. In case of enzymes specifically, they are proteins and so have long chains of amino acids folded into different structures and shapes.
What are the silly bandz shapes?
there are lots. some are animals, band shapes, plants, princess and lots more,
Why are shapes important?
shapes symbolize many things. for instance a cirlce unity, a square power. and a diamond resembles a royalty
