Photosynthesis and Cell Respiration
• 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?
A. 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.
B. As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.
• 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.
Objectives
• Photosynthesis and Cellular Respiration• Students will be able to
• Identify reactants and products• Explain the relationship
• Compare and contrast
Exploration
• Modeling Photosynthesis and Cellular Respiration
• Black beads = carbon atoms• White beads = hydrogen atoms• Red beads= oxygen atoms
• Atom/Molecule
