Cell Structure & Processes Test

Front

What is osmosis?

Back

Osmosis refers to the diffusion of water specifically, moving from areas of high concentration to areas of low concentration.

Front

What is the rough endoplasmic reticulum?

Back

The rough endoplasmic reticulum is a type of endoplasmic reticulum that has embedded ribosomes where proteins are made.

Front

What process converts glucose, oxygen, water, and carbon dioxide into energy?

Back

The process is cellular respiration, which converts these molecules into energy in the form of ATP.

Front

What is the function of the endoplasmic reticulum?

Back

The endoplasmic reticulum transports substances from one place to another in the cell.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of compounds that pass electrons along, ultimately producing ATP through oxidative phosphorylation.

Front

Define diffusion.

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to power various cellular processes.

Front

What are ribosomes?

Back

Ribosomes are cellular structures where proteins are synthesized, either free in the cytoplasm or attached to the rough endoplasmic reticulum.

Front

What is the role of mitochondria?

Back

Mitochondria are the powerhouse of the cell, where cellular respiration occurs and ATP is produced.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.
