CELLULAR RESPIRATION

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert nutrients into energy, typically in the form of ATP, using oxygen.

Front

What is the primary function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, where cellular respiration occurs and ATP is produced.

Front

What is the equation for cellular respiration?

Back

The equation for cellular respiration is: C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 (carbon dioxide) + 6H2O (water) + energy (ATP).

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce energy, while anaerobic respiration occurs without oxygen.

Front

What is ATP and why is it important?

Back

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

Front

What role do enzymes play in cellular respiration?

Back

Enzymes act as catalysts in cellular respiration, speeding up the chemical reactions involved in breaking down glucose.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration, occurring in the cytoplasm, where glucose is broken down into pyruvate.

Front

What happens during the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, occurs in the mitochondria and processes pyruvate to produce electron carriers (NADH and FADH2) and ATP.

Front

What is the electron transport chain?

Back

The electron transport chain is the final stage of cellular respiration, where electrons are transferred through a series of proteins, leading to the production of ATP.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows cells to produce energy without oxygen, resulting in byproducts like lactic acid or ethanol.
