During the cell cycle, specifically g1 interphase, a cell must reach a sufficient size and produce enough atp in order to
a. undergo mitosis.
b. undergo cytokinesis.
c. produce 2 daughter cells.
d. replicate its chromosomes.

What happens as electrons move along the chain of molecules known as the electron transport chain? they gain energy, which causes atp molecules to lose phosphate groups. they gain energy, which causes h *ions to join with oxygen to produce water. they lose energy, which is then used by the cell to make atp. they lose energy, which is then used to break down atp.
