A diagram representing the relationship between photosynthesis and cellular respiration is shown here. The numbered boxes in the diagram represent which of the following?

• 1 - water; 2 - nitrogen
  
• 1 - nitrogen; 2 - oxygen
• 1 - oxygen; 2 - carbon dioxide
• 1 - carbon dioxide; 2 – water

A weightlifter is using heavy weights in short bursts for a  competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?

• As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen.
• As the cells run out of oxygen, they die off gradually and the weightlifter's   muscles have fewer contracting muscle cells.
• The cells will never run out of oxygen if the weightlifter is breathing
• As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP

The primary role of oxygen in cellular respiration is to

• yield energy in the form of ATP as it is passed down the respiratory chain
• act as an acceptor for electrons and hydrogen, forming water.
• combine with carbon, forming CO2
• combine with lactate, forming pyruvate

Which process in eukaryotic cells will proceed normally whether oxygen (O2) is present or absent? 

• electron transport
• glycolysis
• Krebs Cycle
• Electron transport chain

Terrestrial plants have stomata on the surface of their leaves. Stomata are surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. Which of the following best explains how the structure of the leaf is used in processes that occur in plants?

•  Water enters the plant through the surface of the leaf for transpiration
• Gases for photosynthesis are exchanged through the surface of the leaf
• Energy for cellular reproduction is absorbed through the surface of the leaf
•  Carbon dioxide enters the plant through the surface of the leaf for cellular reproduction
