An enzyme (/ ˈ ɛ n z aɪ m /) is a protein that acts as a biological catalyst by accelerating chemical reactions.The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.

5 days ago · Enzyme, a catalyst that regulates the rate at which chemical reactions proceed in living organisms without itself being altered in the process. Most critically, enzymes catalyze all aspects of cell metabolism. Learn more about enzymes in this article.

Dec 8, 2023 · Lipases: This group of enzymes help digest fats in the gut. Amylase: In the saliva, amylase helps change starches into sugars. Maltase: This also occurs in the saliva, and breaks the sugar maltose ...

May 12, 2021 · Enzymes are proteins that help speed up chemical reactions in our bodies. Enzymes are essential for digestion, liver function and much more. Too much or too little of a certain enzyme can cause health problems.

Apr 4, 2025 · The meaning of ENZYME is any of numerous complex proteins that are produced by living cells and catalyze specific biochemical reactions at body temperatures.

Jul 22, 2022 · Etymology: from German “enzym”, from Medieval Greek “enzūmos”, meaning ‘leavened’.

May 28, 2018 · Two explanations of how enzymes interact with substrates are the "lock and key" model, proposed by Emil Fischer in 1894, and the induced fit model, which is a modification of the lock and key model that was proposed by Daniel Koshland in 1958.In the lock and key model, the enzyme and the substrate have three-dimensional shapes that fit each other.

Introduction. In chemistry, a catalyst is a chemical that drives a reaction forward. Catalysts lower the activation energy, which is the amount of energy required for reactants to form products (Figure 1).Catalysts also lower the kinetic barrier, which is needed to drive a …

We are ushering in a new era of bio production through the creation of novel enzymes that address unmet market needs.

Nov 15, 2015 · Enzymes are biological catalysts (also known as biocatalysts) that speed up biochemical reactions in living organisms, and which can be extracted from cells and then used to catalyse a wide range ...
