Respiration

Front

What is respiration?

Back

Respiration is the biochemical process in which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to produce ATP (adenosine triphosphate), which is used as energy by cells.

Front

What are the two main types of respiration?

Back

The two main types of respiration are aerobic respiration (which requires oxygen) and anaerobic respiration (which does not require oxygen).

Front

What is glycolysis?

Back

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

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows glycolysis to continue by regenerating NAD+ from NADH, enabling the production of ATP without oxygen.

Front

What is the role of the Electron Transport Chain?

Back

The Electron Transport Chain is a series of protein complexes in the inner mitochondrial membrane that transfer electrons and produce a large amount of ATP.

Front

What is the correct equation for cellular respiration?

Back

6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy.

Front

What is lactic acid and when is it produced?

Back

Lactic acid is a byproduct of anaerobic respiration in muscles, produced when oxygen levels are low during intense exercise.

Front

How does photosynthesis differ from cellular respiration?

Back

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

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.
