In glycolysis of cellular respiration, the pyruvate amounts to c^3h^4o^3. the amount for carbon and oxygen make sense as there are two pyruvates and together they amount to 6 carbons and 6 oxygens (the amount glucose has), but the amount of hydrogens don't add up. there are 8 in total (from both pyruvates) and 2 going to nadh, but that amounts to 10 hydrogens, not 12. are the other two hydrogens used during glycolysis elsewhere? are they released in a different form? am i missing something? ?

18. determine whether each stateme blank space given. ach statement is true (t) or false (f). place your answer in the 8. when a cell is put into an isotonic solution, individual wat put into an isotonic solution, individual water molecules cannot move back and forth across the cell membrane. d. when a cell is put into a hypertonic solution, there is a net movement of water molecules across the cell membrane into the cell. c. when a cell is put into a hypotonic solution, there is a net movement of water molecules across the cell membrane out of the cell. d. the movement of any solvent across a semi-permeable membrane is called osmosis. e. carrier proteins have the ability to change shape and physically move molecules across the cell membrane. f. in facilitated diffusion, the concentration of the molecules to be moved across the cell membrane is higher inside the cell.
