Cell Respiration

Front

What is cell respiration?

Back

Cell 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 cell respiration?

Back

The main stages of cell respiration are Glycolysis, Krebs Cycle, and Electron Transport Chain.

Front

What is glycolysis?

Back

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

Front

Where does the Krebs Cycle occur?

Back

The Krebs Cycle occurs in the mitochondria of the cell.

Front

What are the products of the Krebs Cycle?

Back

The products of the Krebs Cycle include carbon dioxide, ATP, and electron carriers (NADH and FADH2).

Front

What is the role of oxygen in cell respiration?

Back

Oxygen acts as the final electron acceptor in the Electron Transport Chain, allowing for the production of a large amount of ATP.

Front

What is the Electron Transport Chain?

Back

The Electron Transport Chain is the final stage of cell respiration, occurring in the inner mitochondrial membrane, where electrons are transferred through a series of proteins, leading to ATP production.

Front

What are the reactants of cell respiration?

Back

The reactants of cell respiration are glucose (sugar) and oxygen.

Front

How are photosynthesis and cell respiration related?

Back

Photosynthesis and cell respiration are interconnected processes; the products of photosynthesis (glucose and oxygen) are the reactants for cell respiration, and vice versa.

Front

What is lactic acid fermentation?

Back

Lactic acid fermentation is an anaerobic process that occurs when oxygen is scarce, converting glucose into lactic acid and producing a small amount of ATP.
