Photosynthesis vs. Cellular Respiration

Photosynthesis: process where plants and other organisms use sunlight to synthesize food from carbon dioxide and water
                   
Light Dependent Reaction and Light Independent Reaction (Calvin Cycle)


Cellular Respiration: process to produce energy in the form of adenosine triphosphate (ATP) through oxidation of food molecules

1. Glycolysis (Does not require O2)
2. Pyruvate Oxidation
3. Kreb's Cycle
4. Electron Transport Chain/ Chemiosmosis

	Cellular Respiration	Photosynthesis
In what	Plants, some bacteria, and animals	Plants and some bacteria
Location	Glycolysis: Cytoplasm Krebs Cycle: Mitochondria Matrix ETC: Inner mitochondrial membrane	Chloroplast
ATP, NADH, FADH2 - Produced	Glycolysis:  4 ATP (2 net ATP)                     2 NADH Pyruvate Oxidation: 2 NADH Kreb's Cycle: 2 ATP                       6 NADH                       2 FADH2                       CO2 Overall: 36-38 ATP	18 ATP 12 NADP
When it can occur	When glucose and oxygen is available	When sunlight, water, and carbon dioxide is available
Function	Break down of food. Energy released	Production of food. Energy captured
Equation	6O2 + C6H12O6 ------> 6CO2 +6H2O + ATP (energy)	light 6CO2 + 12H2O ---------> C6H12O6 + 6O2 + 6H20
