Description

Life on the earth

.

Atmosphere Evolution

.

life takes place only in environments with an excess of energy: in our case, in the sunlight. This concept includes the following facts:
• Cells have to feed continuously
• Cells have to breath continuously
• Cells cannot ever stop producing energy
• Cells use energy to keep many ionic gradients (Ca++, Na+, K+, Cl- etc.)
Gradients are necessary for most cell functions (signal transduction, glucose and AA transport, etc.)
