Cellular Respiration

Front

What is cellular respiration?

Back

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

Front

What are the main stages of cellular respiration?

Back

The main stages of cellular respiration are Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain.

Front

What is the primary purpose of cellular respiration?

Back

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

Front

What is the chemical equation for cellular respiration?

Back

The chemical equation is: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

What role does oxygen play in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is glycolysis?

Back

Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm, where glucose is broken down into pyruvate, producing a small amount of ATP.

Front

What is the Krebs Cycle?

Back

The Krebs Cycle, also known as the Citric Acid Cycle, is the second stage of cellular respiration that occurs in the mitochondria, where pyruvate is further broken down, releasing CO2 and generating ATP and electron carriers.

Front

What is the Electron Transport Chain?

Back

The Electron Transport Chain is the final stage of cellular respiration that occurs in the inner mitochondrial membrane, where electrons are transferred through proteins, leading to the production of a large amount of ATP.

Front

How many ATP molecules are produced in aerobic respiration?

Back

Aerobic respiration produces a total of approximately 38 ATP molecules per glucose molecule.

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.
