Guiding Questions

Cellular Respiration

3

  • photosynthesis - the process by which plants and other autotrophs capture and use light energy to make food from carbon dioxide and water

  • cellular respiration - the process in which oxygen and glucose undergo a complex series of chemical reactions inside cells, releasing energy

  • fermentation - the process by which cells release energy by breaking down food molecules without using oxygen

  • produce - to use a combination of materials and processes to create something new

  • source - the place where something comes from; the point where something begins

Draw

Figure 1 : Biking takes a lot of energy! Your body uses cellular respiration to get energy from the food you eat, such as trail mix.

Draw arrows on Figure 1 to show the flow of energy from the food into the biker, and then out into the environment as heat and motion.

Draw

Sketch on the graph to show how the biker's energy level may change over time as they start biking, stop for a snack, start biking again, and finish their ride.
