Enzymes are catalysts and increase the speed of a chemical reaction without themselves .A chemical reaction can be represented by a chemical equation. An enzyme is a protein that speeds up a biochemical reaction .
The enzyme equation, often represented as a simplified version of the Michaelis-Menten equation, describes the rate of enzymatic reactions. It can be expressed as ( v = \frac{V_{max}[S]}{K_m + [S]} ), where ( v ) is the reaction velocity, ( [S] ) is the substrate concentration, ( V_{max} ) is the maximum reaction velocity, and ( K_m ) is the Michaelis constant. This equation illustrates how the rate of reaction depends on substrate concentration and enzyme saturation.
The general equation for all enzymatic reactions is: Substrate + Enzyme → Enzyme-Substrate Complex → Enzyme + Product. Enzymes catalyze reactions by lowering the activation energy required for the reaction to occur, thereby increasing the rate of the reaction.
Enzymes do not participate in chemical reactions or undergo permanent changes. Instead, they facilitate chemical reactions by lowering the activation energy required for the reaction to occur. The enzyme-substrate complex forms during the reaction, and the enzyme is regenerated after the reaction is complete.
Reaction catalyzed by enzyme B > reaction catalyzed by enzyme A > uncatalyzed reaction. Enzymes speed up reactions by lowering the activation energy required for the reaction to occur, making them faster than uncatalyzed reactions. The specificity and efficiency of enzyme-substrate interactions determine the rate of reaction catalyzed by different enzymes.

The Michaelis-Menten equation describes the rate of enzyme-catalyzed reactions by relating the reaction rate to substrate concentration. It establishes two key parameters: ( V_{\max} ), the maximum reaction rate when the enzyme is saturated with substrate, and ( K_m ), the Michaelis constant, which indicates the substrate concentration at which the reaction rate is half of ( V_{\max} ). This relationship helps in understanding enzyme efficiency and affinity for substrates, providing insights into enzyme kinetics.
Catalytic efficiency, represented by the ratio kcat/km, is important in enzyme kinetics as it measures how effectively an enzyme can convert substrate into product. A higher kcat/km value indicates a more efficient enzyme, leading to a faster reaction rate. This efficiency is crucial in determining the overall speed and effectiveness of a chemical reaction catalyzed by the enzyme.
The equation for the production of lactic acid after glycolysis is pyruvate + NADH + H+ -> lactate + NAD+. This reaction is catalyzed by the enzyme lactate dehydrogenase.
The word equation "substrate + enzyme = product" represents the process of enzyme-catalyzed reactions. Enzymes are proteins that act as biological catalysts, speeding up chemical reactions by lowering the activation energy required for the reaction to occur. Substrates bind to the enzyme's active site, where the reaction takes place to form products.
Based on Michaelis-Menten enzyme kinetics, the initial rate of reaction, vi, is dependent on maximum rate Vmax, substrate concentration [S], and the enzyme's Michaelis constant Km, which represents the the tendency of the substrate/enzyme complex to dissociate. The dependence on enzyme concentration is factored into the maximum rate. The equation to describe this is: vi = Vmax([S]/(Km+[S])) Follow the link below for details.

Enzymes speed up reactions by lowering the activation energy required for the reaction to occur, making them faster than uncatalyzed reactions. The specificity and efficiency of enzyme-substrate interactions determine the rate of reaction catalyzed by different enzymes.
