10.2 The Process of Cellular Respiration Flashcard

Front

What is the innermost compartment of a mitochondrion?

Back

Matrix

Front

What is the first stage of cellular respiration that involves the breakdown of glucose?

Back

Glycolysis

Front

What product forms when glucose is broken down during glycolysis?

Back

2 molecules of pyruvic acid (C3H4O3)

Front

What cycle occurs in the matrix of the mitochondrion, breaking down pyruvic acid into carbon dioxide?

Back

The Krebs cycle

Front

How many molecules of ATP are produced from one molecule of glucose during cellular respiration?

Back

36 molecules of ATP

Front

What is released as a byproduct of the Krebs cycle?

Back

Carbon dioxide (CO2)

Front

What are the three stages of aerobic cellular respiration?

Back

Glycolysis, Krebs cycle, Electron transport chain

Front

What is the main purpose of cellular respiration?

Back

To convert glucose into usable energy (ATP) for the cell.

Front

What is the chemical equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Front

What is the role of oxygen in aerobic respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain.
