Cellular Respiration - 10th Bio

Front

What is the main purpose of cellular respiration?

Back

To convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the first step of cellular respiration?

Back

Glycolysis, which breaks down glucose into pyruvate.

Front

What is Acetyl-CoA and its role in cellular respiration?

Back

Acetyl-CoA is an energy-rich molecule formed from pyruvate that enters the Krebs Cycle.

Front

What occurs during the Krebs Cycle?

Back

Acetyl-CoA is oxidized to produce ATP, NADH, FADH2, and carbon dioxide.

Front

What is the electron transport chain?

Back

A series of proteins in the inner mitochondrial membrane that transfer electrons and produce ATP.

Front

What is the final electron acceptor in aerobic respiration?

Back

Oxygen, which combines with electrons and protons to form water.

Front

What is lactic acid fermentation?

Back

A process that occurs in muscles when oxygen is scarce, converting pyruvate into lactic acid.

Front

What is the difference between aerobic and anaerobic respiration?

Back

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

Front

What are NADH and FADH2?

Back

They are electron carriers that transport electrons to the electron transport chain.

Front

What is the overall equation for cellular respiration?

Back

6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy (ATP).
