Enzymes are biological molecules that act as catalysts to speed up chemical reactions in living organisms.

• Enzymes are proteins that are made up of long chains of amino acids.

• They work by lowering the activation energy needed for a chemical reaction to occur.

• Enzymes are specific to the reactions they catalyze, often referred to as lock and key model.

• Examples include amylase breaking down starch into sugars and catalase ...read more

Factors such as temperature, concentration, catalysts, and surface area can affect the rate of action.

• Temperature: Higher temperatures generally increase the rate of action as molecules move faster.

• Concentration: Higher concentrations of reactants can lead to more collisions and faster reactions.

• Catalysts: Catalysts can speed up reactions by providing an alternative pathway with lower activation energy.

• Surface area: In...read more

Activators/inhibitors are substances that either increase or decrease the activity of a biological process or enzyme.

• Activators are substances that increase the activity of a biological process or enzyme.

• Inhibitors are substances that decrease the activity of a biological process or enzyme.

• Examples include enzyme activators like ATP and enzyme inhibitors like penicillin.

• Activators can bind to enzymes and increase their...read more

pH is a measure of acidity or alkalinity of a solution on a scale of 0 to 14.

• pH stands for 'potential of Hydrogen'

• It measures the concentration of hydrogen ions in a solution

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline

• Examples: Lemon juice has a pH of around 2, while baking soda has a pH of around 9
