Question

nerves work fast -- for the most part. tell your body to jump up and hit a volleyball, and youll find yourself up in the air a fraction of a second later. but some cell processes can be much slower. proteins, for instance, can take a around two minutes for a cell to assemble because they have so many small pieces. the nerve cell simulation sped up some processes so you didnt have to sit and wait several minutes while large molecules were being built. now that you know proteins are built much more slowly than the nerve cell fires, what can you conclude about how things work in a real nerve cell? select the best answer. nerve cells fire immediately once a protein is produced. it takes several minutes for nerve cells to fire. nerve cells make and store proteins well before they actually fire, so the proteins are ready when theyre needed. nerve cells dont actually use proteins at all.

Explanation:

• The text mentions that proteins take around two minutes to assemble as they have many small pieces.
• The nerve cell simulation sped up some processes so one didn't have to wait several minutes while large molecules (like proteins) were being built.
• This implies that in a real nerve cell, proteins are made and stored in advance (before the nerve cell actually fires) so that when the nerve cell needs to function (fire), the proteins are already ready.

Answer:

Nerve cells make and store proteins well before they actually fire, so the proteins are ready when they're needed.
