2024 Bio Acc Exam Cellular Respiration, Exercise, & Diabetes

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 main stages of cellular respiration?

Back

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

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the role of the mitochondria in cellular respiration?

Back

Mitochondria are known as the powerhouse of the cell, where the Krebs cycle and electron transport chain take place.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows cells to produce energy without oxygen, resulting in products like lactic acid or ethanol.

Front

What are the reactants of cellular respiration?

Back

The reactants of cellular respiration are glucose and oxygen.

Front

What is the main product of cellular respiration?

Back

The main product of cellular respiration is ATP (adenosine triphosphate), which is used as energy by the cell.

Front

How does oxygen contribute to cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What happens to blood glucose levels during exercise?

Back

During exercise, blood glucose levels may decrease as the pancreas releases insulin, allowing cells to take in glucose for energy.

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.
