Cellular Respiration
Review: Heterotrophs vs. Autotrophs
Heterotrophs must consume others for energy (consume producers)
Autotrophs produce their own energy compounds (photosynthesis or chemosynthesis)
break down glucose to useable form of energy (ATP)
cellular respiration
Cellular Respiration
C6H12O6 + 6O2 ———> 6CO2 + 6H2O + ATP
process of breaking down glucose for making ATP
aerobic (requires oxygen)
Mitochondrion
site of cellular respiration
contains required enzymes & folded membranes (surface area)
Cellular Respiration
Step-wise reaction
Glycolysis= Breaks down glucose
Krebs cycle= Releases CO2
Electron transport chain (ETC)= Uses O2 and makes H2O, makes most ATP
Cellular Respiration
ATP
Adenosine triphosphate
Stores energy in unstable phosphate bonds
Made within cells (mitochondria)
Used for cellular transport and work
Breaking/Making ATP
ATP breaks down to form ADP + P
ADP = adenosine diphosphate
P = phosphate
Broken bond releases energy, ADP more stable
ATP can be reformed!
ADP + P and ATP
Mitochondria and Chloroplasts
Similarities?
Process Connection
Interdependence photosynthesis - cellular respiration
