Cellular Respiration

Front

What is the primary purpose of cellular respiration?

Back

The primary purpose of cellular respiration is to make ATP.

Front

What happens when a phosphate group is removed from an ATP molecule?

Back

A substantial amount of energy is released.

Front

How do photosynthesis and cellular respiration differ in terms of carbon dioxide?

Back

Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.

Front

Why is ATP referred to as a cell's 'energy currency'?

Back

Because most of the energy that drives metabolism is supplied by ATP.

Front

What type of organism is yeast classified as?

Back

Yeast is classified as a fungus.

Front

What are the three main stages of cellular respiration?

Back

Glycolysis, Krebs cycle, and Electron Transport Chain.

Front

What is glycolysis?

Back

Glycolysis is the process of breaking down glucose into pyruvate, producing a small amount of ATP.

Front

What is the Krebs cycle?

Back

The Krebs cycle is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What role does oxygen play in cellular respiration?

Back

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

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.
