WebA catalyst speeds up a reaction by providing an alternate reaction pathway with a lower activation energy. A lower activation energy means that more molecules will have enough energy to react, which translates to a greater rate of reaction. Quora User Founder at The Penny Hoarder (2010–present) Updated Mar 15 Promoted WebThe 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 …

WebHow do catalysts speed up chemical reactions? In biological systems, the energy required to make a reaction go is stored primarily in the bonds that make up adenosine triphosphate (ATP). Specifically, the energy is stored in the bonds between phosphate groups and the nucleotide, adenosine. Energy (~7 kcal/mole) is released when one of the ...

WebJan 20, 2024 · How does the addition of a catalyst increase the rate of a chemical reaction? A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. timothy francis baker
