Mechanisms MechanismsofofCellular CellularRespiration RespirationandandPhotosynthesis Photosynthesis

PHOTOSYNTHESIS

Converts carbon dioxide into glucose by using solar energy

CELL RESPIRATION

Breaks down glucose to produce usable chemical energy

Calvin Cycle

involves carbon fixation, reduction of G3Pmolecules, andribulose 1,5- bisphosphate regeneration.

Mitochondria

Key organelle for respiration

Chlorophyll

Key organelle for Photosynthesis

Glucose and oxygen molecules

Reactants of respiration

Carbon dioxide and water molecules

Reactants of photosynthesis

Exergonic

Energetics of respiration

Endergonic

Energetics of photosynthesis

Generally catabolic

Metabolics of respiration

Generally anabolic

Metabolics of photosynthesis

Glycolysis

Involves primarily the break down of glucose

Krebs Cycle

GeneratesNADH, CO2, FADH2, and G3P

Electron Transport Chain

Results in pumping of H+ into the intermembrane

Chemiosmosis

Passive movement of H+ drives ATP synthesis
