Cellular Respiration

Front

What is cellular respiration?

Back

Cellular respiration is a metabolic process that converts glucose and oxygen into energy (ATP), carbon dioxide, and water. It occurs in both autotrophs and heterotrophs.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to produce ATP, which serves as the energy currency of the cell.

Front

Why is ATP referred to as a cell's 'energy currency'?

Back

ATP is called a cell's 'energy currency' because it provides the energy needed for various cellular processes and metabolic reactions.

Front

What are the reactants of cellular respiration?

Back

The reactants of cellular respiration are glucose and oxygen.

Front

What is produced as a result of cellular respiration?

Back

The products of cellular respiration are ATP, carbon dioxide, and water.

Front

What happens to muscles during intense activity?

Back

During intense activity, muscles may feel sore due to the accumulation of lactic acid, which is produced when oxygen levels are low.

Front

What is the role of glucose in cellular respiration?

Back

Glucose serves as the primary fuel source for cellular respiration, providing the energy needed to produce ATP.

Front

What is the significance of oxygen in cellular respiration?

Back

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

Front

What is lactic acid fermentation?

Back

Lactic acid fermentation is an anaerobic process that occurs when oxygen is scarce, converting glucose into lactic acid and producing a small amount of ATP.

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.
