What is cellular respiration?

Back

Cellular respiration is a biochemical process in 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, and the Electron Transport Chain.

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 and NADH.

Front

What is the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions in the mitochondria that produces high-energy electron carriers (NADH and FADH2) and carbon dioxide from pyruvate.

Front

What is the electron transport chain?

Back

The electron transport chain is the final stage of cellular respiration, located in the inner mitochondrial membrane, where electrons are transferred through a series of proteins, leading to the production of a large amount of ATP.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows cells to produce energy without oxygen, typically resulting in the production of lactic acid or ethanol.

Front

What is the role of oxygen in cellular respiration?

Back

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

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

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.

Front

What are the raw materials for cellular respiration?

Back

The raw materials for cellular respiration are glucose and oxygen.
