Cellular Respiration

What is the balanced chemical equation for cellular respiration?

• C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (ATP)

• C6H12O6 + 3O2 → 3CO2 + 3H2O + Energy (ATP)

• C6H12O6 + 6O2 → 3CO2 + 3H2O + Energy (ATP)

• C6H12O6 + 6O2 → 6CO + 6H2O + Energy (ATP)

What is the relationship between photosynthesis and cellular respiration?

• They are the same process occurring in different organisms.

• They are opposite reactions. The raw materials for one reaction are the products of the other reaction.

• Photosynthesis occurs only at night, while cellular respiration occurs during the day.

• Both processes require oxygen to occur.

What waste gas is produced during cellular respiration?

• Oxygen (O2)

• Nitrogen (N2)

• Carbon dioxide (CO2)

• Hydrogen (H2)

What is the energy produced by respiration called?

• Adenosine triphosphate (ATP)

• Glucose

• Nicotinamide adenine dinucleotide (NADH)

• Lactic acid

What is the role of glucose in cellular respiration?

• Glucose is the primary fuel that is broken down to release energy.

• Glucose is a waste product of cellular respiration.

• Glucose is used to build proteins in the cell.

• Glucose is converted into oxygen during respiration.

What are the end products of anaerobic respiration in yeast?

• Ethanol and carbon dioxide.

• Oxygen and glucose.

• Lactic acid and water.

• Acetic acid and hydrogen.

What is the significance of ATP in cellular respiration?

• ATP is a type of sugar used in cellular respiration.

• ATP is the energy currency of the cell, used for various cellular processes.

• ATP is a waste product of cellular respiration.

• ATP is a protein that helps in the transport of oxygen.

How does the body use the energy produced from cellular respiration?

• For digestion and absorption of nutrients.

• For growth, repair, movement, and maintaining homeostasis.

• For storing fat and carbohydrates only.

• For producing hormones and enzymes exclusively.

What is the role of oxygen in cellular respiration?

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

• Oxygen is used to break down glucose into pyruvate during glycolysis.

• Oxygen is a byproduct of the Krebs cycle and has no role in ATP production.

• Oxygen is required for the synthesis of fatty acids in the mitochondria.

What is the difference between respiration and breathing?

• Respiration is a physical process of inhaling and exhaling air, while breathing is a chemical process of energy production.

• Respiration is a chemical process of energy production, while breathing is the physical process of inhaling and exhaling air.

• Respiration and breathing are the same processes with no difference.

• Breathing is a process that occurs only in humans, while respiration occurs in all living organisms.
