Review - 4.4 - Cellular Respiration & Biosynthesis

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 primary purpose of cellular respiration in plants?

Back

The primary purpose of cellular respiration in plants is to release energy stored in glucose molecules.

Front

What role does oxygen play in cellular respiration?

Back

Oxygen is essential for cellular respiration as it acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is biosynthesis?

Back

Biosynthesis is the process by which living organisms produce complex molecules from simpler ones, often using energy from cellular respiration.

Front

Why do plants need nitrogen from the soil?

Back

Plants need nitrogen from the soil to build large plant parts like proteins, which are essential for growth and development.

Front

Where does the carbon that contributes to a plant's dry mass come from?

Back

The carbon that contributes to a plant's dry mass primarily comes from carbon dioxide in the air.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What are the byproducts of cellular respiration?

Back

The byproducts of cellular respiration are carbon dioxide and water.

Front

How do plants obtain the glucose needed for cellular respiration?

Back

Plants obtain glucose through the process of photosynthesis, where they convert sunlight, carbon dioxide, and water into glucose.
