Question

MEDAL!
I know muscle weighs more than fat, but by how much?

Answer 1

It is not wrong to say that muscle weighs more than fat. In fact, almost 20 % more. The reason is that the fat cells primarily contains triglycerides, which are lighter than the proteins and the water, such as muscle cells is built from. Around 87 % of fat cell is fat. The remaining 13 % percent consists among other things of the cell membrane, the cell's nucleus and the mitochondria, which produce energy. Muscle cells, also called muscle fibers, are some pretty special cells - mainly because they are great. Certain muscle fibers are many cm long, for example because they move from one end of the large oblique muscle of the thigh to the other. The very elongated cells is typically between 0.02 and 0.1 mm in diameter. They have several nuclei, located at intervals near the cell's outer wall. Namely, they are formed by the fusion of a large number of cells that are precursors of muscle fiber. Normally, the cells tend to only a single core, and the size of them are measured in millionths of a meter. A typical fat cell is approx. 0.1 mm in diameter. The main component of the muscle cells are long wires, called myofibrils. The causes muscles to contract. They are located in the longitudinal direction of the muscle cell and is mainly composed of proteins actin and myosin. In addition, the cells are very rich in mitochondria that produce the chemical energy that myofibrillerne need to pull together. All in all muscle cells rich in elements that are heavier than the elements that are most of the fat cells. Therefore, considering a cubic centimeter muscle 1.06 grams, while the same volume of adipose tissue weigh 0.9 grams.

Answer 2

thank you soooo much!
where did you get this information?

Answer 3

Information I have collected through high school and the university I have combined into an answer... the books would among others be:
- Bremer j. Molecular biology and biochemistry (danish book)
- Reece, J. B. Campbell Biology.
- Stryer Biochemistry.
- Compledium in bioenergetics by N. J. Willumsen.

okay thanks! :)
