Why don't muscle cells burst when you exercise?

AI Thread Summary
Muscle growth occurs through muscle hypertrophy, which involves an increase in sarcoplasmic fluid within muscle cells. Concerns were raised about whether this fluid accumulation could cause cell membranes to burst. The discussion clarified that as muscle cells grow, the synthesis of lipids, which are the primary components of cell membranes, occurs. These newly synthesized lipids integrate with the existing membrane, effectively expanding its surface area and preventing rupture. This understanding reassures that muscle cells can accommodate growth without compromising their structural integrity.

One way muscle grows is muscle hypertrophy where sarcoplasmic fluid increases inside the muscle cell. Wouldn't this burst the cell membrane, I can understand how organelles can replicate but what about the cell membrane. I know this sounds like a stupid question but please help. Thanks :smile:

lipids are the main component of cell membrane. I think as muscle grows cell membrane lipids are synthesized and they simply join the pre-existing membrane and increase it's surface to resist cell rupture.

Yes for the time being I'll think like that. Thanks :smile:

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
