Hi!

Recalling what you have learned about cells, you marvel at the ability of these tiny things to support their life functions. You then remember that they could not easily get much bigger without drastic changes. Explain why cells are so small, considering the relationship between surface area and volume for objects of different sizes but similar shapes.

The reason cells are so small is because the fact that they need to diffuse through other materials more efficiently.

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.

2%? i tried finding the exact sorry if it's not 100% correct ; -;
