Study Notes
Energy and ATP
- ATP primarily performs energy transfer and storage functions in living cells.
Energy Sustenance
- ATP doesn't run out in living systems because it is constantly being regenerated and recycled through cellular processes.
Energy in Closed Systems
- In a closed system, free energy decreases over time, leading to an increase in entropy and disorder.
Energy Release Pathways
- Catabolic pathways, such as glycolysis, citric acid cycle, and fatty acid oxidation, release energy in cells.
Light Energy Utilization
- Living cells primarily use light energy through photosynthesis, where light energy is converted into chemical energy in the form of ATP and NADPH.
