Are enzymes permanently change in the chemical reactions they are involved in?
No. That is one of the definitions of an enzyme. It is NOT altered in the reaction.
When the stabilized state of an equilibrium system is altered further chemical reactions begin until a new equilibrium is reached?
True
How are physical and chemical reactions different?
Physical reactions mean that the substance hasn't been altered in terms of its composition. For example, liquid water turning into an ice cube is a physical change. It is still H2O - just different form. However, burning paper is chemical change, since ash + H2O + CO2 is not paper.
Whenever a characteristic and chemical composition of weathered materials have altered they have undergone?
Chemical weathering.
Whenever the characteristics and chemical composition of weathered materials have been altered they have undergone .?
Chemical weathering
Matter that does not enter chemical reactions is described as what?
Matter that does not enter chemical reactions is described as inert. This type of matter cannot be altered by chemical reactions.
Are enzymes permanently change in the chemical reactions they are involved in?
No. That is one of the definitions of an enzyme. It is NOT altered in the reaction.
Are antibodies proteins that catalyze chemical reactions without being physically altered?
True
How does the interaction between an enzyme and its substrates change chemical reaction?
Enzymes speed up the chemical reactions because when it forms a complex with its substrates, it reduces the activation energy that the reaction needs to proceed. Remember that the reaction itself is not altered, only the rate of reaction, and that the enzyme is not used or altered in the reactions.

Is it difficult to separate compounds and mixtures?
A compound can be separated from a mixture without being chemically altered; the separation of elements from a compound need chemical reactions.
Do most enzymes increase the activation energy of the reactions they catalyze?
No. A catalyst helps a reaction to occur but usually remains unchanged itself. Enzymes are catalysts that either remain unchanged or are returned to their original state by other biological reactions.
What are Enzymes are responsible for?
Enzyme, a substance that acts as a catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process.

What are enzymes..?
Enzymes are a type of protein that significantly speed up the rate of chemical reactions within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism. Enzyme is also a catalyst that regulates the rate at which chemical reactions proceed in living organisms without itself being altered in the process.
