Front

What is ATP and why is it important for organisms?

Back

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

Front

Which organisms perform cellular respiration?

Back

Both plants and animals perform cellular respiration to produce ATP.

Front

What is homeostasis?

Back

Homeostasis is the tendency of an organism to maintain a balanced internal state to stay healthy.

Front

What process do mitochondria perform?

Back

Mitochondria perform cellular respiration, converting nutrients into ATP.

Front

What is the main difference between photosynthesis and cellular respiration?

Back

Photosynthesis converts light energy into chemical energy (glucose), while cellular respiration converts glucose into ATP.

Front

What happens to brain cells without oxygen?

Back

Without oxygen, brain cells cannot make enough ATP, leading to cell damage or death.

Front

Define cellular respiration.

Back

Cellular respiration is the process by which cells convert glucose and oxygen into ATP, carbon dioxide, and water.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is essential for cellular respiration as it acts as the final electron acceptor in the electron transport chain.

Front

What is the equation for cellular respiration?

Back

The equation for cellular respiration is: C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP.

Front

What is the significance of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell because they generate ATP through cellular respiration.
