Download Chemical equation for aerobic respiration • C6H12O6 + 6O2

Chemical equation for aerobic respiration
 C6H12O6 + 6O2  6CO2 + 6H2O + chemical energy
 glucose + oxygen  carbon dioxide + water + ATP
Photosynthesis and respiration are the opposite of each other
Photosynthesis
Plants
* use sunlight to make glucose
* take in carbon dioxide
* give off oxygen
*carbon dioxide + water + sunlight
 glucose + oxygen
Respiration
Animals and plants
* eat plants to get glucose
* take in oxygen
* give off carbon dioxide
*glucose + oxygen  carbon
dioxide + water + ATP
1. All organisms require energy. What is this energy used for?
2.
What is the ultimate source of energy on Earth? Why?
3.
Distinguish between an autotroph and a heterotroph.
4. What is the source of oxygen (an atmospheric byproduct) produced during photosynthesis?
5. Cell respiration is the process by which all / some (circle your choice) organisms release energy
stored in organic molecules (glucose) to power cell activities.
6. How are photosynthesis and cellular respiration almost opposite processes?
