QSE Review(updated both q1 & q2)

Front

What is osmosis?

Back

Osmosis is the passive transport 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 the products of cellular respiration?

Back

The products of cellular respiration are carbon dioxide and water, along with energy (ATP).

Front

What is the purpose of cell transport?

Back

The purpose of cell transport is to maintain homeostasis by regulating the movement of molecules across the cell membrane, ensuring equilibrium on both sides.

Front

What happens during the anaphase of mitosis?

Back

During anaphase, chromosomes are separated and pulled apart towards opposite poles of the cell.

Front

When does DNA replication occur in the cell cycle?

Back

DNA replication occurs during the S phase (Synthesis phase) of the cell cycle.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move molecules across the cell membrane without energy.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy (ATP).

Front

Define homeostasis in the context of cells.

Back

Homeostasis is the process by which cells maintain a stable internal environment despite changes in external conditions.

Front

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) serves as the primary energy currency of the cell, providing energy for various cellular functions.

Front

What is the difference between simple diffusion and facilitated diffusion?

Back

Simple diffusion is the passive movement of molecules directly through the membrane, while facilitated diffusion requires specific transport proteins.
