What else can I help you with?
Are enzymes able to heat up molecules so they can react?
Enzymes do not heat up molecules to make them react. Instead, enzymes lower the activation energy required for a reaction to occur, thus speeding up the reaction by providing an alternative pathway. This allows reactions to happen at a biologically relevant temperature without the need for additional heat.
The graph below shows how two different enzymes react with a substrate as the temperature increases. Based on the results what conclusion can be drawn about the action of the enzymes as the temperatur?
enzyme B stays effective at higher temperatures than enzymes A
What is true about the most reactants in living things?
Enzymes that help them react do not work at normal body temperatures
How does low temperatures affect enzymes?
cold temperatures cause enzymes to inactivate, meaning they are no longer useful. at height temperatures enzymes denature, meaning they are also no longer useful. The difference is that at low temperature, when an enzyme inactivates it can always be heated, and used again. Yet after an enzyme is denatured by heat it is destroyed, this is because the heat causes the enzymes to lose its shape, making it imposible for the substrate to react with the enzyme.
Why might enzyme's activity decrease at very high temperatures?
Enzymes activity is affected by temperature. At a very high temperature, enzymes became denature that means they lose their original shape, which is important for them to react. Thus, enzyme activity decreases at a very high temperature.
What can enzymes react with?
Substrates
Does enzyme affect jello?
*Do enzymes react with jello?
How does the enzymes in bacteria react to antiseptics?
The enzymes in the body are probably get destroyed by the antiseptics. Antiseptics are usually poisons for humans also and they ruthlessly kill the bacteria.
Are enzymes able to heat up molecules so they can react?
Enzymes do not heat up molecules to make them react. Instead, enzymes lower the activation energy required for a reaction to occur, thus speeding up the reaction by providing an alternative pathway. This allows reactions to happen at a biologically relevant temperature without the need for additional heat.
Will all enzymes react the same way with two enantiomers?
no, enzymes are very specific with respect to stereo-chemistry and usually is active only to one enantiomer
What is true about reactants in living things?
Enzymes that help them react do not work at normal body temperatures
What is meant by the enzyme specificity?
Enzymes work on one substrate specifically. This is why there is millions of different types of enzymes to interact with all the molecules they need to metabolically and chemically react with.
The graph below shows how two different enzymes react with a substrate as the temperature increases. Based on the results what conclusion can be drawn about the action of the enzymes as the temperatur?
enzyme B stays effective at higher temperatures than enzymes A
What substance takes place in an enzymatic reaction but does not change shape?
Enzymes. Substrates react with the active site of the enzyme and are broken down. Enzymes stay the same throughout the reaction.
