Exothermic and Endothermic Reactions
Photosynthesis and Respiration are the primary examples of energy transfer in biological systems.
Is photosynthesis exothermic or endothermic?
What is Exothermic and Endothermic Reactions?
"Exothermic and endothermic reactions are chemical processes that release or absorb energy respectively."
Respiration is described as exothermic because it:
On a very hot, bright day, the rate of photosynthesis might actually slow down. Why?
Which change would usually increase the rate of photosynthesis if light intensity is the limiting factor?
Which word equation correctly represents photosynthesis?
Energy Transfer
Photosynthesis: Endothermic (takes in light energy).
Respiration: Exothermic (releases energy to the surroundings).
This energy flow is the basis of all food chains on Earth.
Endothermic = Energy IN. Exothermic = Energy OUT.
