Cellular Respiration

Front

What is the process of breaking the outer phosphate bond of ATP called?

Back

This process is known as hydrolysis, and it releases energy for cellular activities.

Front

Where does the Krebs cycle occur in eukaryotic cells?

Back

The Krebs cycle occurs in the mitochondrial matrix.

Front

What is the role of NAD+ in anaerobic respiration?

Back

NAD+ is regenerated during fermentation to allow glycolysis to continue.

Front

What do NADH and FADH2 donate electrons to during cellular respiration?

Back

They donate electrons to hydrogen ion pumps in the electron transport chain.

Front

Which stage of cellular respiration produces the most ATP?

Back

The Electron Transport Chain produces the most ATP in eukaryotic cells.

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 three main stages of cellular respiration?

Back

The three main stages are Glycolysis, the Krebs Cycle, and the Electron Transport Chain.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What is the main purpose of the Krebs cycle?

Back

The main purpose of the Krebs cycle is to produce electron carriers (NADH and FADH2) for the electron transport chain.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows for the regeneration of NAD+ to continue glycolysis when oxygen is not available.
