Front

What happens to an egg placed in a hypertonic solution like corn syrup?

Back

The egg will shrink (get smaller) due to water moving out of the egg.

Front

What macromolecule is known to be hydrophobic (dislikes water)?

Back

Lipids are hydrophobic macromolecules.

Front

True or False: Enzymes are used up in the reactions they catalyze.

Back

False. Enzymes are not used up and can be reused.

Front

What is the process of taking small molecules (monomers) and building them into large molecules (polymers) called?

Back

Synthesis (Anabolic) is the process of building larger molecules from smaller ones.

Front

Why is pure water not used in IVs in hospitals?

Back

Pure water would cause cells to expand due to osmosis, potentially leading to cell damage.

Front

What is osmosis?

Back

Osmosis is the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

Define hypertonic solution.

Back

A hypertonic solution has a higher concentration of solutes compared to another solution.

Front

Define hypotonic solution.

Back

A hypotonic solution has a lower concentration of solutes compared to another solution.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions without being consumed.

Front

What are the four main types of macromolecules?

Back

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