A reaction profile includes the activation energy, which is the minimum energy needed by particles when they collide for a reaction to occur. The activation energy is shown as a 'hump' in the line ...

starts at the energy of the reactants is equal to the difference in energy between the top of the 'hump' and the reactants The overall change in energy in a reaction is the difference between the ...

cells release the energy stored in their food molecules through a series of oxidation reactions. Oxidation describes a type of chemical reaction in which electrons are transferred from one ...

Part 3. Charged particle activation: 3–1. Calculation of excitation functions for charged particle induced reactions; 3.–2. Activation cross-sections for elements from lithium to sulphur; 3–3. Thick ...

The answer is enzymes. Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called ...

Some bonds, such as those between carbon and hydrogen (C–H bonds), are particularly strong and require considerable energy to ...
