By changing the speed of the reaction.
Enzymes act as catalysts. They speed up the reaction time.
activation energy of the reaction.
Enzymes affect reactions in living cells by lowering the activation energy required for the reactions to occur, thus speeding up the rate of chemical reactions. They do this by binding to specific substrates and catalyzing the conversion of these substrates into products. This enables cells to carry out essential biological processes efficiently.
Activation energy! They change the amount of energy needed for a reaction to occur, through different mechanisms, message me if you want more information :)
Enzymes lower the activation energy (or free energy of activation for the very scientific) of the chemical reactions they catalyse. The enzymes can make a reaction proceed much more quickly than it otherwise would by astronomical figures, e.g. 109 times! Enzymes don't affect the equilibrium position, but they do affect the rate.
Enzymes play a key role in determining the fate of a chemical reaction in a living cell by catalyzing and regulating the speed of the reaction. Additionally, the intracellular concentration of reactants and products can also affect the direction and equilibrium of the reaction within the cell.
enzymes. Enzymes are biological catalysts that increase the rate of chemical reactions in living organisms without being consumed in the process. They help lower the activation energy required for a reaction to occur.
The function of enzymes in living things is to catalyze (instigate, speed up) chemical reactions.
Catalysts that are active working in the body are called enzymes.
enzymes
Enzymes are the most common type of catalyst that affect biochemical reactions. They are proteins that facilitate specific chemical reactions in living organisms, speeding up the reaction without being consumed in the process.
A catalyst. Definition from Pretence Hall Biology: A catalyst is a protein that speeds up the rate of a chemical reaction.
