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.
