40%
Only 40% of energy is converted to useful work. The rest is given off as heat to maintain homeostasis
The energy is 95 x 40 watt-seconds (Joules).
40%
Approximately 40% of the energy in glucose is released as heat during cellular respiration. The rest of the energy is converted into ATP, which is used by the cell for various functions.
Well, 40 percent of 250 I guess! Which, if you are not good at arithmetic is 100 Joules.
About 40% of the energy derived from glucose is converted to ATP through cellular respiration. The rest is released as heat.
ATP is the only usable source of energy by cells.ATP is released through aerobic respiration, however, aerobic respiration is only 40% efficient, and so the other 60% of energy is lost as heat energy.Put simply, the energy released in aerobic respiration is: ATP (40%) and heat (60%).
Leaving an appliance on standby means it is using 40% of the energy it would if it was actually running.
Basic math Every time speed doubles energy potential energy quadruples 40 to 80 km 40 km x 4 = energy to brake (E) 80 to 120 energy doubles E x 2 = Energy to brake So (energy at 40 KM x 4) x 2 = Energy to brake

Power = (energy used) / (time to use that much energy) = 40/5 = 8 watts
