What is cellular respiration?

Back

Cellular respiration is the process by which cells break down food molecules to produce energy in the form of ATP and release carbon dioxide as a byproduct.

Front

Where does cellular respiration occur in the cell?

Back

Cellular respiration occurs in the mitochondria, known as the powerhouse of the cell.

Front

What are the main reactants of cellular respiration?

Back

The main reactants are glucose (C₆H₁₂O₆) and oxygen (O₂).

Front

What are the main products of cellular respiration?

Back

The main products are ATP (energy), carbon dioxide (CO₂), and water (H₂O).

Front

What is the chemical equation for cellular respiration?

Back

The equation is: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP).

Front

How does cellular respiration provide energy for the cell?

Back

It breaks down glucose molecules, releasing energy stored in chemical bonds to form ATP.

Front

What role does oxygen play in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, enabling efficient ATP production.

Front

What happens to the carbon dioxide produced during cellular respiration?

Back

Carbon dioxide is released as a waste product and expelled from the body through respiration.

Front

How is cellular respiration related to photosynthesis?

Back

Cellular respiration uses the glucose and oxygen produced during photosynthesis to generate energy, completing the cycle of matter and energy.

Front

Why is cellular respiration important for living organisms?

Back

It provides the energy needed for essential life processes, such as growth, repair, and maintaining homeostasis.
