In a multicellular organism, different cells are specialized for certain functions to the whole organism maintain the living state. as cells differentiate to become specialized, the abundance of different organelles shifts to best serve those needs. which organelle might be expected to be present in high abundance in a mammal's muscle cells that must extract large amounts of energy from food molecules to support the work of muscle contraction?

Well the only organelle that produces ATP/cellular energy is the mitochondria so via process of elimination you would conclude mitochondria are most abundant in muscle cells.

this website is for anybody really not just for girls just saying, also while a lot of males are mean and you know there are the few who are kind and then there's the nice-guys but then theirs also guys like me who are shy we don't get out much because there are people like you who exist who would most likely punch a guy in the face so next time just think about things before you post them to a website where guys and girls can see your question.
