Biochemistry

Front

What is the role of enzymes in chemical reactions?

Back

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

Front

What type of molecule is water?

Back

Water is a polar molecule, meaning it has a partial positive charge on one side and a partial negative charge on the other.

Front

What is the pH of a strong acid?

Back

A strong acid typically has a pH of 1 or lower.

Front

What is the correct polymer/monomer pair for carbohydrates?

Back

The correct pair is polysaccharides: monosaccharides.

Front

What happens to heat when water evaporates?

Back

Water absorbs heat when it evaporates, which is why evaporation has a cooling effect.

Front

What is the function of lipids in biological systems?

Back

Lipids serve as energy storage, structural components of cell membranes, and signaling molecules.

Front

Define the term 'monomer'.

Back

A monomer is a small, basic molecular unit that can join together to form polymers.

Front

What is the significance of the pH scale in biochemistry?

Back

The pH scale measures the acidity or basicity of a solution, which is crucial for enzyme activity and biochemical reactions.

Front

What are the four main types of macromolecules in biochemistry?

Back

The four main types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

How do hydrogen bonds affect the properties of water?

Back

Hydrogen bonds give water its unique properties, such as high surface tension, high specific heat, and solvent capabilities.
