what causes muscle cells to switch from aerobic cellular respiration to fermentation in order to obtain energy for movement?

what's the rest of the question

one centimetre is equal to 0.01 metres

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.

the answer is definitely 36.

hope this : )
