Cell Reactions and Energy

Cells must perform thousands of different chemical reactions in order to survive.  These reactions are crucial to providing cells with energy. Endergonic reactions: -“energy in” require energy in order to proceed – biological endergonic reactions produce molecules that store energy (ex. Glucose) – Ex. Photosynthesis Exergonic reatctions: – “energy out” release energy – biological exergonic…

Where are Active Volcanoes?

Volcanoes formed at certian locations because they were along plate boundaries, which provide the ideal circumstances for magma formation and its subsequent eruption. At subduction boundaries the lithopsheres collide and the denser plate is pulled down into the mantle. This introduces water into the asthenosphere which lowers melting temperature and allows the less dense magma…
