Unit 3 Cells Review questions

Front

What is the function of the Golgi apparatus in a cell?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is homeostasis in the context of cellular function?

Back

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

Front

What is diffusion?

Back

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

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space.

Front

What is glycolysis?

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP and NADH.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move molecules against their concentration gradient, while passive transport does not require energy.

Front

What are proteins and their role in the body?

Back

Proteins are large molecules made up of amino acids that perform various functions, including building tissues, transmitting signals, and supporting immune responses.

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 role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various biochemical reactions.

Front

What is the role of the endoplasmic reticulum (ER) in a cell?

Back

The endoplasmic reticulum is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), and it also plays a role in detoxification.
