Many of the biochemical reactions that occur within cells are catalyzed by enzymes. which of the following statements is true about most enzyme-assisted reactions?

I don't see answer choices but enzymes make it so less energy is needed to begin and reaction and basically speeds up can be done in the body

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
