How do fish extract oxygen from water?

• Through their skin

• Using specialized lungs

• With gills

• By drinking water

Do plants require oxygen for any metabolic processes?

• No, they only produce oxygen through photosynthesis.

• Yes, they need oxygen for cellular respiration.

• Only during the night when photosynthesis is not occurring.

• Only when they are growing new leaves.

What are the necessary inputs (reactants) for aerobic cellular respiration?

• Carbon dioxide and water

• Glucose and oxygen

• ATP and carbon dioxide

• Water and ATP

What is the primary role of oxygen in aerobic cellular respiration?

• To act as a catalyst for glucose breakdown.

• To help break down glucose and form ATP.

• To produce carbon dioxide.

• To directly generate water.

What does the acronym ATP stand for?

• Adenosine Diphosphate

• Adenine Triphosphate

• Adenosine Triphosphate

• Amino Transfer Protein

When ATP releases energy for cellular processes, what molecule is typically formed?

• ADP

• AMP

• Glucose

• Pyruvate

Which of the following organisms can produce ATP even in the absence of oxygen?

• Fish

• Plants

• Humans

• Yeast

What is a key characteristic of fermentation compared to anaerobic respiration?

• Fermentation produces more ATP than anaerobic respiration.

• Fermentation involves the Krebs cycle and electron transport chain.

• Fermentation primarily relies on glycolysis and a mechanism to regenerate NAD+.

• Fermentation requires an oxygen substitute as a final electron acceptor.

What happens to a molecule when it gains electrons?

• Oxidized

• Reduced

• Hydrolyzed

• Synthesized

What is the primary purpose of fermentation in cells?

• To produce large amounts of ATP

• To break down glucose completely

• To regenerate NAD+ for glycolysis

• To create oxygen for cellular respiration
