Explain why gluconeogenesis requires the input of six molecules of nucleoside triphosphates (four atps and two gtps) per molecule of glucose synthesized, whereas glycolysis yields only two molecules of atp per molecule of glucose.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
