What are transport proteins?

Back

Transport proteins are specialized proteins that assist in the movement of molecules across the cell membrane, facilitating the passage of substances that cannot cross the membrane freely.

Front

What is a hypotonic solution?

Back

A hypotonic solution is one where the concentration of solutes outside the cell is lower than inside the cell, causing water to flow into the cell, leading to swelling.

Front

What is the function of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, maintaining homeostasis and protecting the cell's internal environment.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts, which contain chlorophyll and are responsible for converting light energy into chemical energy.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, used to power various cellular processes.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the cellular structures responsible for protein synthesis, translating messenger RNA into polypeptide chains.

Front

What is the difference between hypertonic and hypotonic solutions?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing the cell to lose water and shrink, while a hypotonic solution has a lower concentration of solutes, causing the cell to gain water and swell.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is osmosis?

Back

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

Front

What are nucleic acids?

Back

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