What does it mean if a species is anaerobic?

• Anaerobic species require oxygen for cellular respiration.

• Anaerobic species do not require oxygen for cellular respiration and may produce byproducts like ethanol or lactic acid.

• Anaerobic species can only survive in water environments.

• Anaerobic species thrive in high-oxygen environments.

What is glycolysis and where does it occur?

• A process that converts glucose into energy, occurring in the mitochondria.

• The first stage of cellular respiration that breaks down glucose into pyruvate, occurring in the cytoplasm.

• A method of protein synthesis that occurs in the ribosomes.

• A type of fermentation that takes place in the nucleus.

Where is most of the energy from glucose stored at the end of the Krebs cycle?

• In ATP

• In FADH2

• In NADH

• In glucose itself

What is the primary role of oxygen in cellular respiration?

• Oxygen is used to produce glucose.

• Oxygen acts as an acceptor for electrons and hydrogen, forming water.

• Oxygen is a byproduct of cellular respiration.

• Oxygen is converted into carbon dioxide during respiration.

What is the difference between aerobic and anaerobic respiration?

• Aerobic respiration occurs in the absence of oxygen and produces less ATP.

• Anaerobic respiration requires oxygen and produces more ATP.

• Aerobic respiration requires oxygen and produces more ATP.

• Anaerobic respiration occurs in the presence of oxygen and produces more ATP.
