Unit 5: Cellular Respiration Review

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 is the primary energy currency of the cell?

Back

ATP (adenosine triphosphate) is the primary energy currency of the cell, used to power various cellular processes.

Front

Where does cellular respiration occur in eukaryotic cells?

Back

Cellular respiration occurs primarily in the mitochondria of eukaryotic cells.

Front

What are the main stages of cellular respiration?

Back

The main stages of cellular respiration are glycolysis, the Krebs cycle (citric acid cycle), and the electron transport chain.

Front

What is glycolysis?

Back

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

Front

What is the role of the mitochondrion in cellular respiration?

Back

The mitochondrion is the organelle responsible for producing ATP through the processes of the Krebs cycle and the electron transport chain.

Front

What is the byproduct of cellular respiration?

Back

The byproducts of cellular respiration are carbon dioxide and water.

Front

How does ATP provide energy to the cell?

Back

ATP provides energy by releasing a phosphate group, which transforms it into ADP (adenosine diphosphate) and releases energy for cellular work.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

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 through the oxidation of acetyl-CoA.
