Chemistry of Life Review Game

Front

What negatively affects the efficient function of an enzymatic reaction?

Back

Changes in pH and temperature.

Front

What is the role of carbon in living organisms?

Back

Carbon can form four covalent bonds and complex structures.

Front

What is a chemical reaction?

Back

A process by which atoms or groups of atoms are reorganized into different substances.

Front

How are energy changes related to chemical reactions?

Back

There is a change in energy caused by the formation/breaking of chemical bonds, and chemical reactions can release or absorb energy in the form of heat.

Front

What is activation energy?

Back

The amount of energy that needs to be added for a chemical reaction to start.

Front

What is the significance of pH in enzymatic reactions?

Back

pH affects the shape and function of enzymes, which can alter their activity.

Front

What is a covalent bond?

Back

A chemical bond formed by the sharing of electrons between atoms.

Front

What is the difference between exothermic and endothermic reactions?

Back

Exothermic reactions release energy, while endothermic reactions absorb energy.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as catalysts to speed up chemical reactions by lowering the activation energy.

Front

What is a substrate in enzymatic reactions?

Back

The reactant molecule that an enzyme acts upon.
