Cellular Respiration

Front

What is glycolysis?

Back

Glycolysis is the first stage of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP and NADH. It occurs in the cytoplasm and does not require oxygen.

Front

What does anaerobic mean?

Back

Anaerobic means 'without oxygen'. It refers to processes that occur in the absence of oxygen, such as glycolysis.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What are the main products of cellular respiration?

Back

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

Front

What is the correct sequence of stages in cellular respiration?

Back

The correct sequence is Glycolysis, Krebs cycle, and Electron transport chain.

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 takes place in the mitochondria, where pyruvate is further broken down to produce ATP, NADH, and FADH2.

Front

What role does oxygen play in cellular respiration?

Back

Oxygen is the final electron acceptor in the electron transport chain, allowing for the production of a large amount of ATP.

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 is fermentation?

Back

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

Front

What is the electron transport chain?

Back

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