Cellular Respiration HW Flashcard

Front

What is Cellular Respiration?

Back

The process by which cells break down food molecules to produce ATP (adenosine triphosphate), the energy currency of the cell.

Front

What is the main purpose of cellular respiration?

Back

To release energy from glucose for cellular activities.

Front

Which organisms perform cellular respiration?

Back

All living organisms, including plants, animals, fungi, and microorganisms.

Front

In which organelle does cellular respiration occur?

Back

Mitochondrion.

Front

What are the main products of cellular respiration?

Back

Carbon dioxide and water.

Front

What is ATP?

Back

Adenosine triphosphate, a molecule that stores and transfers energy within cells.

Front

What is glycolysis?

Back

The first step of cellular respiration that occurs in the cytoplasm, breaking down glucose into pyruvate and producing a small amount of ATP.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of a large amount of ATP.

Front

What is fermentation?

Back

An anaerobic process that allows cells to produce energy without oxygen, resulting in products like lactic acid or ethanol.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.
