Enzymes lower activation energy, and therefore increase the reaction rate. Does an enzyme affect the structure of the transition state? Explain. Explain how the structure of an enzyme relates to how well the function catalyzes chemical reactions. ...
How do enzymes affect reactions?Activation Energy:The activation energy of a reaction is the amount of energy needed to cause the reaction to start. Not all chemical reactions have an activation energy, and some will start spontaneously without any added energy or catalyst. One example of this ...

Investigating how Concentration Effects the Rate of Reaction OBJECTIVES Carry out experiments safely Find out what happens to rates of reactions when concentration is increased Explain results scientifically Apparatus and Chemicals Boiling tube Test tube rack Ruler Stopwatch Measuring cylinder Scissors Boiling...
What are enzymes and how they operate? Enzymes are the molecules in our bodies that facilitate reactions. They perform this function at their active site, which is like their ‘mouth’. The substrate – the ‘food’ in this metaphor – binds to the mouth and is molecularly modified: it is...
of proteins, carbohydrates, fats and other compounds, such as: The chiral reduction catalyzed by amino acid dehydrogenase, ammonia formate dehydrogenase, and glucose dehydrogenase all require the help of nicotinamide adenine dinucleotide to complete the entire reaction, as does the oxidation reaction. ...
Describe the structure and function of enzymes, and indicate how temperature and pH affect the rate of enzyme reactions. Explain the functions of enzymes and enzyme inhibitors. Explain how an enzyme lowers the required energy of activation for a reaction. Why ar...
How can enzymes lower activation energy? How does enzymes lower activation energy when they catalyze reactions? What is a detailed chemical explanation for how an enzyme lowers the activation energy of a chemical reaction? How does an enzyme work to increase the rate of a reaction? How do enzym...
