Back

Enzymes are required for all biochemical reactions to occur in a biological system.

Front

What is the atomic number of oxygen and what does it signify?

Back

The atomic number of oxygen is 8, indicating it has 8 protons and 8 electrons.

Front

Why are non-polar molecules generally insoluble in water?

Back

Non-polar molecules are insoluble in water due to their inability to form hydrogen bonds with water molecules.

Front

What is the electronegativity difference between two identical atoms?

Back

The electronegativity difference between two identical atoms is 0.

Front

What is the range of electronegativities for the main 6 elements found in life?

Back

The range of electronegativities for the main 6 elements found in life is 2.0-3.5.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms, influencing the formation of molecules.

Front

What is a hydrolytic reaction?

Back

A hydrolytic reaction is a chemical reaction that involves the breaking of a bond in a molecule using water.

Front

What is a dehydration reaction?

Back

A dehydration reaction is a chemical reaction that involves the removal of water to form a bond between molecules.

Front

How does the structure of a molecule affect its solubility?

Back

The structure of a molecule, particularly the presence of polar or non-polar regions, affects its solubility in different solvents.

Front

What is the role of hydrogen bonding in solubility?

Back

Hydrogen bonding increases the solubility of polar substances in water.
