Total questions: 10
Worksheet time: 5mins
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.
