What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, resulting in a decrease in temperature.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings, resulting in an increase in temperature.

What two elements make up water?

Back

Hydrogen and oxygen.

What is the role of enzymes in chemical reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What are lipids?

Back

Lipids are a group of biomolecules that include fats, oils, and waxes, and are primarily used for energy storage and structural components in cells.

Front

What is activation energy?

Back

Activation energy is the minimum amount of energy required to initiate a chemical reaction.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the difference between a reactant and a product?

Back

A reactant is a substance that undergoes a chemical change in a reaction, while a product is a substance that is formed as a result of that reaction.

Front

What is a chemical reaction?

Back

A chemical reaction is a process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

Front

What are carbohydrates?

Back

Carbohydrates are biomolecules made up of carbon, hydrogen, and oxygen, and are primarily used for energy and structural support in living organisms.
