Cellular Respiration
November 16
Do Now• Collect returned assignments (in hanging
folders)• Pick up a new tracker• Begin working on today’s warm-up:
What is aerobic exercise?
Upcoming assessments• Individual! Quizlet on Tuesday/Wednesday – Food webs & Energy flow– Photosynthesis
• Individual! Quest on Monday/Tuesday– Food webs & Energy Flow– Photosynthesis– Cellular Respiration– Carbon Cycle– 1 question recycled from Quiz 1
Photosynthesis & Energy Flow Concept Check
Photosynthesis & Energy Flow Concept Check
• Where do plants get their energy?
Photosynthesis & Energy Flow Concept Check
• Where do plants get their energy?
Photosynthesis & Energy Flow Concept Check
• What is the equation for photosynthesis?
Photosynthesis & Energy Flow Concept Check
• What is the equation for photosynthesis?
+ + +
Water + Carbon Dioxide + Energy Sugar + Oxygen
Photosynthesis & Energy Flow Concept Check
• Where do consumers (heterotrophs) get their energy?
Photosynthesis & Energy Flow Concept Check
• Where do consumers (heterotrophs) get their energy?– From the food
they eat!
Photosynthesis & Energy Flow Concept Check
• What happens to the energy available to an organism?
Photosynthesis & Energy Flow Concept Check
• What happens to the energy available to an organism?– MOST of the energy they use– SOME of the energy moves into the atmosphere
as heat– 10% of the energy is stored in plant tissues
Photosynthesis: Storing energy from the sun in sugar
Photosynthesis: Releasing energy in sugar to power life
Cellular respiration:: Releasing energy in sugar to power life
Objective
• Compare and contrast photosynthesis and cellular respiration.
By the end of class, students will be able to:
Cellular respiration takes place in mitochondria
Inputs of cellular respiration: sugar
Inputs of cellular respiration: sugar
Return to the warm-up• What is aerobic exercise?
Inputs of cellular respiration: oxygen
Outputs of cellular respiration: energy
Outputs of cellular respiration: carbon dioxide
CarbonOxygen
Oxygen
Outputs of cellular respiration: water
Oxygen
HydrogenHydrogen
Equation of cellular respiration
Sugar + Oxygen Energy + Carbon Dioxide + Water

INPUTS OUTPUTS
What is the relationship between the equations for photosynthesis and cellular respiration?
Who uses cellular respiration?
Who uses cellular respiration?• Every organism with access to oxygen– Animals AND Plants
• Fermentation is less efficient– (less energy per molecule of sugar)
Organisms without access to oxygen break down sugar for energy by fermentation
Fermentation results in alcohol or lactic acid
Humans can use fermentation during anaerobic exercise
Lactic acid in your muscles makes you sore
Muscles specialized for aerobic and anaerobic activity explain dark and light meat in turkey.

Compare and contrast photosynthesis and cellular respiration
Exit ticket• How are the outputs (products) of
photosynthesis related to the inputs (reactants) of cellular respiration?
