Electron Carriers and Overview of Respiration Steps (H)

Front

What are NADH and FADH2?

Back

NADH and FADH2 are loaded electron carriers that transport electrons to the electron transport chain during cellular respiration.

Front

What is the role of ATP in glycolysis?

Back

ATP provides the energy required to initiate glycolysis, with an investment of 2 ATP molecules.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the end product of glycolysis?

Back

The end products of glycolysis are 2 pyruvate molecules, 2 ATP, and 2 NADH.

Front

What is the significance of the mitochondrial matrix?

Back

The mitochondrial matrix is where the Krebs cycle occurs, producing electron carriers for the electron transport chain.

Front

What is the function of electron carriers in respiration?

Back

Electron carriers like NADH and FADH2 transport electrons to the electron transport chain, facilitating ATP production.

Front

What is the total ATP yield from glycolysis?

Back

The total ATP yield from glycolysis is 4 ATP, but 2 ATP are used in the process, resulting in a net gain of 2 ATP.

Front

What is the process of 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 three main stages of cellular respiration?

Back

The three main stages of cellular respiration are glycolysis, the Krebs cycle, and the electron transport chain.

Front

What is the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy.
