What happens to the chemical energy that is extracted from molecules by cellular activities but that is not used for cellular work?
  • The ordering of one system depends on the disordering of another.This is the correct answer.Selected:
  • arrangement of atoms within molecules
  • The energy leaves the system as heat.
  • The aerobic respiration of glucose generates heat.
In plant cells, carbon dioxide and water are joined to form carbohydrates. Plant cells can also break down carbohydrates such as glucose, releasing carbon dioxide, water, and energy. No one has ever observed such reactions between water and carbon dioxide outside of living cells. What allows simple molecules to assemble into more complex molecules, and also disassemble, in cells but not in other, nonbiological environments?
  • ATP converting to ADP + P in order to help reduce a 3 carbon molecule in the Calvin Cycle
  • The aerobic respiration of glucose generates heat.
  • Cells couple energy-releasing reactions to energy-requiring reactions.
