Biology Midterm Review

Front

What are lipids?

Back

Lipids are biomolecules that act as energy storage for cells and also cushion and insulate organs.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a greater solute concentration outside of the cell compared to the inside.

Front

What is the function of mitochondria?

Back

Mitochondria produce ATP (cellular energy) by breaking down glucose.

Front

What is the role of the endoplasmic reticulum?

Back

The endoplasmic reticulum synthesizes lipids and proteins, and processes materials that are exported from the cell.

Front

What is chlorophyll?

Back

Chlorophyll is the primary pigment involved in photosynthesis, allowing plants to absorb light energy.

Front

What are carbohydrates?

Back

Carbohydrates are biomolecules that serve as a primary energy source for cells.

Front

What is the function of proteins in cells?

Back

Proteins perform a variety of functions including catalyzing biochemical reactions, providing structure, and regulating processes.

Front

What are nucleic acids?

Back

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

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 the difference between hypotonic and hypertonic solutions?

Back

A hypotonic solution has a lower solute concentration outside the cell, while a hypertonic solution has a higher solute concentration outside the cell.
