Respiration in Living Organisms

What is the primary function of respiration in living organisms?

• To produce glucose from sunlight

• To absorb water and release oxygen

• Obtain energy from oxygen and release carbon dioxide

• To regulate body temperature

Name the two types of respiration.

• Cellular respiration and transpiration

• Photosynthesis and fermentation

• Aerobic respiration and anaerobic respiration

• Inhalation and exhalation

Where does the process of respiration take place in a cell?

• Cell membrane

• Endoplasmic reticulum

• Nucleus

• Mitochondria

What is the chemical equation for aerobic respiration?

• 2H2O + 2NADH + 6O2 → 6H2O + 2NAD+ + 4H+ + 3ATP

• C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy

• C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

• C6H12O6 + 6O2 → 6CO2 + 6H2O + Heat

Explain the difference between aerobic and anaerobic respiration.

• Aerobic respiration produces less energy than anaerobic respiration

• Anaerobic respiration requires oxygen to produce energy

• Aerobic respiration requires oxygen to produce energy, while anaerobic respiration does not require oxygen and produces less energy.

• Aerobic respiration requires less energy than anaerobic respiration

What is the role of oxygen in respiration?

• Oxygen is used to break down glucose and produce energy in the form of ATP.

• Oxygen is used to produce carbon dioxide

• Oxygen is used to produce sunlight

• Oxygen is used to produce water

How is energy released during the process of respiration?

• By absorbing sunlight directly

• By converting water into glucose

• By breaking down glucose in the presence of oxygen

• By breaking down fats in the absence of oxygen

What are the waste products of respiration?

• sodium and potassium

• carbon dioxide and water

• oxygen and glucose

• nitrogen and methane

Explain the concept of cellular respiration.

• The process by which cells break down glucose to produce energy

• The process by which cells break down oxygen to produce energy

• The process by which cells break down carbon dioxide to produce energy

• The process by which cells break down water to produce energy

How does respiration contribute to the survival of living organisms?

• It causes fatigue and reduces the ability to survive

• It depletes the oxygen levels in the body, leading to suffocation

• It has no impact on the survival of living organisms

• It provides the necessary energy for survival by producing ATP.
