 Explain the interrelationships between the processes of photosynthesis and cellular respiration comparing and contrasting photosynthesis and cellular respiration reactions.
 Determine what factors affect the processes of photosynthesis and cellular respiration (i.e., light intensity, availability of reactants, temperature).

 What ultimately provides energy for living things?
What provides energy for us?

 Plants and other types of organisms are able to use light energy from the sun to produce food.
 What is the difference between autotrophs and heterotrophs?
 Give an example of an autotroph.
 Give an example of a heterotroph.


As you write you are “burning” fuel.
 Living things use chemical fuels.
 Adenosine Triphosphate (ATP) – large carbon molecule with THREE PHOSPHATE
GROUPS.

 When you remove the third phosphate from ATP a large amount of energy is released.
 Enough energy for active transport, protein synthesis, and muscle contraction.
(Remind me to show you a picture of a guy with too much ATP/Steroids)

POP QUIZ – If adenosine triphosphate loses a phosphate, is it still ATP?
Then what is it?
(Adenosine diphosphate or ADP which still has energy…just not as much)
