(a) What can affect the function of enzymes? (b) Why do enzymes change with ambient temperature? Why are enzymes important to humans? a. because they are proteins b. because they can evade the laws of thermodynamics c. because they allow reactions to occ...
How do enzymes catalyze reactions? a) Enzymes bind with and change the conformation of substrates. b) Enzymes carry out a reaction without needing reactants. c) Enzymes are denatured by a reaction to catalyze it. d) Enzymes increase the activation ene ...
Translation: The mRNA is carried back out of the nucleus by the cell's enzymes. The virus then uses the cell's natural protein-making mechanisms to make long chains of viral proteins and enzymes. Assembly: RNA and viral enzymes gather at the edge of the cell. An enzyme called protease cu...
Enzymes, critically, are not changed in the reactions they catalyze – at least not after the reaction is over. But they do undergo temporary changes during the reaction itself, a necessary function in allowing the reaction at hand to proceed. To carry the lock-and-key analogy further, when ...
results. This is due to theenzymesbeing most active at 60ᵒC‚ it was that results were going to be most active at the 41ᵒC which is close to humanbodytemperature. When we compare theenzymein the lowtemperaturesto theenzymesin the highertemperaturewe observed that ...
When enzymes are being developed for appli- cation in new areas, a major challenge is the stability of the enzyme to inactivation during isolation or use in its new environment. Stability can come from sourcing enzymes from harsh environments or from enzyme-specific optimization campaigns using ...
Enzymes lower the amount of activation energy needed by binding to the reactants of the reaction they catalyze, thus speed up the reaction and can process millions of molecules per second. Enzymes are typically large proteins with high molecular weight that permit reactions to go at conditions th...
If you have read How Cells Work, you know that all cells contain thousands of enzymes. These enzymes do all of the work necessary for the cell to live its life. According to this article, the actual mechanism that causes browning in apples and potatoes involves an enzyme called polyphenol ...
How can I do the calculations of an assay for an enzyme activity? Enzymes act to lower the activation energy of a chemical reaction. How do enzyme do this? How does pH affect enzyme-catalyzed reactions? a. Proton concentration allows the reactants to reach their transition state b. Protons...
Explain the role of enzymes in living cells. How do enzymes increase the rate of a chemical reaction? Why is Kcat/Km referred to as the efficiency of an enzyme? Why does pH change enzyme activity? How do enzyme molecules react with reactants to produce substrates?
