Phase; (also, second gap) a cell-cycle phase; third phase of interphase where the cell undergoes the final preparations for mitosis.

The G2 phase(second gap) a cell cycle phase and third phase of interphase where the cell undergoes final preparation for mitosis.

Explanation:

G2 phase or second gap phase is a cell growth phase in the which cells continue to grow to produce new proteins and prepare for final mitosis. It is the third stage of interphase, the first and second phase areG1(cell growth), S(synthesis). G2 phase is shorter that G1 and S for it only lasts between 3 to 4 hours in cells.

materials water oxygen those are the things i can think of in this moment.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
