The Halifax Gibbet, a precursor to the guillotine was used in Halifax, England, at executions on market-days. May have functioned as early as 1280. The last execution with the Halifax gibbet took place in 1648. The Maiden was constructed and used in Scotland.
Cellular Respiration in Plants By Robert Korpella; Updated April 25, 2017 Cells in both plants and animals use cellular respiration as a means of converting stored energy into a chemical that individual cells consume. Adenosine triphosphate (ATP) is a chemical food that all cells use. Plants first create a simple sugar through photosynthesis. Individual cells then break down that sugar through cellular respiration.
Okay, great. So how do cells (remember, both plant and animal cells need energy, and neither can directly use the energy provided by the sun) get the energy out of the sugar molecule? They do it with a process called cellular respiration. In cellular respiration, cells use oxygen to break the sugar molecule. That releases the energy which is then transferred to an ATP (adenosine triphosphate) molecule. ATP is the fuel that cells need for energy.
