oxygen for cellular respiration too.
plants need ______________________
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?!!
Factors Affecting Cellular Respiration
1. 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
Factors that affect Cellular Respiration
1. 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!!!!
Check for Understanding
1. Write the equation for Cellular Respiration.
2. What is the name of the molecule the cell uses
to store energy taken from sugar and other
food?
3. Besides sugar what does an organism need in
order to do cellular respiration?
4. What is the name of the organelle where
cellular respiration takes place?
5. If I am not feeling energetic what can I do to
increase my cellular respiration?
