What are ribosomes?

Back

Ribosomes are cellular structures that synthesize proteins. They can be found in both eukaryotic and prokaryotic cells.

Front

What is the importance of DNA replication?

Back

DNA replication is crucial because it creates two identical daughter cells, ensuring that genetic information is passed on during cell division.

Front

What is active transport?

Back

Active transport is the process of moving substances against their concentration gradient, which requires energy.

Front

What is a direct product of cellular respiration?

Back

ATP (adenosine triphosphate) is a direct product of cellular respiration, providing energy for cellular processes.

Front

What does active transport require?

Back

Active transport requires energy to move substances against their concentration gradient.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves substances along their concentration gradient, while active transport requires energy to move substances against their gradient.

Front

What is osmosis?

Back

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

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is the role of ATP in cells?

Back

ATP serves as the primary energy currency of the cell, providing energy for various cellular processes.

Front

What are the two types of cells?

Back

The two types of cells are prokaryotic cells, which lack a nucleus, and eukaryotic cells, which have a nucleus and membrane-bound organelles.
