Ok the question is:
When you work harder, your muscle cells work harder and increase in size. How might various organelles in a muscle cell increase in size, number, or activity to respond to the challenge of an increased workload?
Please only answer if your 100 % sure of you're right. Thanks.

The increase in muscle mass experienced by body-builders is the result fo two changes:
(1) an increase in th diameters of glycolytic fibers, and (2) the addition of collagen and other connective tissue required to sustain the passive tension of heavy loads.

When muscle cells increase in size, they go through mitosis, but not cytokinesis (meaning there are multiple nucleii in one cell).
There would be an increased number of mitochondrion as it needs more energy (ATP) and an increased number of lysosomes (to get rid of more toxins that are being produced).
The cell needs to keep a fairly large surface area to volume ratio; if this doesn't happen there isn't sufficient exchange between the environment and the cell and it will die.
I'm sure there is much more, but I just can't think of everything off the top of my head right now.

whenever i post a question, even if it's the easiest one, they cant provide me a good informed answer here. what happened to people that really make the effort to write an answer?
