Glucose is phosphorylated to form glucose-6-phosphate. ALL biochemical reactions occur only and exclusively through the action of enzymes.
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.
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.
Substrate is the term used to describe a substance that undergoes a reaction catalyzed by an enzyme. It is the substance that is acted upon by the enzyme to form a product. In a chemical reaction, the substrate is the molecule upon which an enzyme acts.
This reaction is a phosphorylation reaction where phosphoenolpyruvate transfers a phosphate group to ADP to form pyruvate and ATP. It is catalyzed by the enzyme pyruvate kinase, an important step in glycolysis for ATP production.
The source of energy for the first step of glycolysis is the hydrolysis of one molecule of ATP to ADP and inorganic phosphate. This reaction is catalyzed by the enzyme hexokinase and helps to phosphorylate glucose to glucose-6-phosphate.
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 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 enzyme graph shows that the reaction rate of the catalyzed reaction is faster compared to the uncatalyzed reaction. This indicates that the enzyme is effectively speeding up the reaction process.
The rate-limiting step of an enzyme-catalyzed reaction is the slowest step in the reaction that determines the overall rate at which the reaction proceeds.
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.

catalyzed reaction
Enzyme concentration has no effect on the rate of an enzyme-catalyzed reaction after reaching a saturation point where all enzyme active sites are occupied. At this point, adding more enzyme will not increase the reaction rate further.
The rate of an enzyme-catalyzed reaction is often referred to as the enzyme's catalytic activity or turnover rate. It is a measure of how quickly the enzyme can convert substrate molecules into products.
