Biology final exam

During daytime, the rate of photosynthesis is faster than the rate of cellular respiration. A plant is placed in a clear, airtight container with a mechanism to allow its roots to get water. Will it be able to sustain itself?

• No, because the plant would need ATP to complete cellular respiration.

• No, because the plant would need oxygen to complete cellular respiration.

  
  

• Yes, because the amount of oxygen produced during the daytime would be enough to allow for

• Yes, because the amount of carbon dioxide produced during the daytime

Sodium and potassium are necessary electrolytes. As a result, the human body uses a great deal of energy keeping these electrolytes in balance. Explain why the body needs to use energy for this process.
