11. slowly in ________________. many steps
CELLULAR RESPIRATION happens __________
in ________________.
If all the energy was released in one step… most would be lost as ____________________!
slowly
many steps
light and heat

12. PHOTOSYNTHESIS CELLULAR RESPIRATION 6 CO2 6 H2O C6H12O6 6O2 C6H12O6
___________ + _________ + ___________ →_______________ + __________
6 CO2
6 H2O
C6H12O6
6O2
CELLULAR RESPIRATION
C6H12O6
6 CO2
_____________ + _________ →________ + __________ + __________
______________________________________________________________
6O2
6 H2O
The two equations are exact opposites!

13. Calorie UNITS FOR MEASURING HEAT ENERGY Food is Energy trapped
UNITS FOR MEASURING HEAT ENERGY
Food is Energy trapped
Unit for measuring energy in food
= _______________
Calorie

14. Plants do ____________ but Flooded Corn Field photosynthesis
By:
plants need ______________________ too.
So plants do Photosynthesis to make their food, then they do cellular respiration to get energy from their food! Does that mean plants are cannibals?!!
oxygen for cellular respiration

15. Factors Affecting Cellular Respiration
Temperature – usually the rate of cellular respiration increases as temperature increases
This is why you sweat more if its hot when you work out or dance or whatever you do to sweat.
You are burning Food for energy, doing more cellular respiration

16. Factors that affect Cellular Respiration
Glucose and Oxygen – The more reactants the cell has, the more energy it can produce
What happens when you don’t eat enough?
No Energy!!!!
Weak!!!!

17. Check for Understanding
Write the equation for Cellular Respiration.
What is the name of the molecule the cell uses to store energy taken from sugar and other food?
Besides sugar what does an organism need in order to do cellular respiration?
What is the name of the organelle where cellular respiration takes place?
If I am not feeling energetic what can I do to increase my cellular respiration?
