Front

What is the primary component of the cell membrane?

Back

The cell membrane is primarily formed by phospholipids.

Front

What property of water allows it to be considered the 'universal solvent'?

Back

Water is considered the 'universal solvent' because it is a polar molecule.

Front

Which type of substances are least likely to dissolve in water?

Back

Nonpolar fats and oils are least likely to dissolve in water.

Front

What elements make up carbohydrates?

Back

Carbohydrates are made up of carbon (C), hydrogen (H), and oxygen (O).

Front

What effect do enzymes have on activation energy?

Back

Enzymes lower activation energy.

Front

Define a polar molecule.

Back

A polar molecule is a molecule that has a partial positive charge on one side and a partial negative charge on the other, leading to an uneven distribution of charge.

Front

What is the role of carbohydrates in living organisms?

Back

Carbohydrates serve as a primary energy source and are important for structural components in cells.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

What is the function of enzymes in biochemical reactions?

Back

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

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have an uneven distribution of charge, while nonpolar molecules have an even distribution of charge.
