Cellular Respiration

Front

What is the definition of an Autotroph?

Back

An organism that produces its own food using sunlight or chemical energy, such as plants.

Front

What is the definition of a Heterotroph?

Back

An organism that cannot produce its own food and must consume other organisms for energy, such as animals.

Front

What organelle is known as the powerhouse of the cell?

Back

Mitochondria, where cellular respiration occurs.

Front

What is the main purpose of cellular respiration?

Back

To convert biochemical energy from nutrients into ATP (adenosine triphosphate), which is used by cells for energy.

Front

What is the chemical equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is required for aerobic respiration to produce ATP efficiently.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.

Front

What is produced during anaerobic respiration in yeast?

Back

Ethanol and carbon dioxide.

Front

What is the significance of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, powering various biological processes.

Front

What is glycolysis?

Back

The first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.
