If muscles are made of cells, how do parts of a cell move?
In: Biology
Your muscle cells are made of units called sarcomeres which are composed of a central support structure called actin and then protein motors called myosin that act as hands that pull on the support to bring two ends of a cell together
Imagine a long rope and you and your friend pull on the rope to bring yourselves together
You have these sarcomeres in the thousands upon thousands in each muscle and they use a lot of energy to do this
