3.2 - Cellular Respiration

Front

What is cellular respiration?

Back

Cellular respiration is the process that our cells use to convert sugar (glucose) into energy (ATP).

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to produce energy.

Front

What is the energy molecule produced during cellular respiration?

Back

ATP (Adenosine Triphosphate) is the energy molecule produced during cellular respiration.

Front

What waste gas is produced by cellular respiration?

Back

The waste gas given off by cellular respiration is carbon dioxide.

Front

In which cell organelle does cellular respiration occur?

Back

Cellular respiration occurs in the mitochondria.

Front

What is the chemical equation for cellular respiration?

Back

The chemical equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

What are the two main stages of cellular respiration?

Back

The two main stages of cellular respiration are glycolysis and the Krebs cycle (Citric Acid Cycle).

Front

What is glycolysis?

Back

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

Front

What role does oxygen play in cellular respiration?

Back

Oxygen is used in the electron transport chain to help produce ATP and is essential for aerobic respiration.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, producing less energy and resulting in byproducts like lactic acid or ethanol.
