In cellular respiration, the energy for most atp synthesis is supplied by:

a. high energy phosphate bonds in organic molecules

b. a proton gradient across a membrane

c. converting oxygen to atp

d. transferring electrons from organic molecules to pyruvate

e. generating carbon dioxide and oxygen in the electron transport chain

5. what might happen if you were to remove all light from the setup after the discs have all become buoyant? describe what you would see. explain why this would occur with relation to cellular processes like respiration. [referring to an ap biology lab in which spinach discs are placed in a sodium bicarbonate solution and exposed to light.]
