2024 Fall Final Semester Review

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a process of passive transport where molecules move across a cell membrane through protein channels from an area of high concentration to an area of low concentration.

Front

Where does DNA replication occur in a eukaryotic cell?

Back

DNA replication takes place in the nucleus of a eukaryotic cell.

Front

What process stores energy in the form of carbon?

Back

Photosynthesis is the process that stores energy in the form of carbon by converting sunlight, carbon dioxide, and water into glucose and oxygen.

Front

Does the sodium-potassium pump require ATP?

Back

Yes, the sodium-potassium pump requires ATP to transport sodium and potassium ions against their concentration gradients.

Front

What is gene expression?

Back

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, often a protein, leading to observable traits.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the role of ribosomes in a cell?

Back

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

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the function of the cell membrane?

Back

The cell membrane protects the cell, provides structure, and regulates the movement of substances in and out of the cell.

Front

What is the difference between simple diffusion and facilitated diffusion?

Back

Simple diffusion is the movement of small or nonpolar molecules directly through the lipid bilayer, while facilitated diffusion involves larger or polar molecules moving through protein channels.
