Mid-Term Review

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell, leading to cell shrinkage.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell, leading to cell swelling.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water and maintaining cell shape.

Front

What is osmosis?

Back

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

Front

What is endocytosis?

Back

Endocytosis is the process by which cells engulf substances from the outside environment, bringing them into the cell.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials to the outside environment, often involving the fusion of vesicles with the cell membrane.

Front

What are proteins?

Back

Proteins are large biomolecules made up of amino acids, essential for various functions in the body, including structure, function, and regulation of tissues and organs.

Front

What are nucleic acids?

Back

Nucleic acids are biomolecules, such as DNA and RNA, that store and transmit genetic information.

Front

What are lipids?

Back

Lipids are a group of hydrophobic biomolecules, including fats and oils, that are important for energy storage and cell membrane structure.

Front

What are carbohydrates?

Back

Carbohydrates are biomolecules made of sugar molecules, serving as a primary energy source and structural components in cells.
