Heart muscle
would you expect skin cells to contain more or fewer mitochondria than muscle cell?
Muscle cell
We would die. Fairly quickly. Modern medical science would not be able to save anyone.
The mitochondria and chloroplasts are organelles that contain functioning ATP synthetase complexes in their membranes. These complexes are responsible for producing ATP through oxidative phosphorylation in the mitochondria and photophosphorylation in the chloroplasts.
Pacemaker cells in the sinoatrial (SA) node of the heart would likely have an unusually high proportion of gap junctions compared to other heart muscle cells. Gap junctions are essential for electrical coupling and coordination of cardiac cell activity, which is critical for generating and conducting the electrical impulses that regulate heart function.
No, the meat does not contain human flesh.
There aren't any (you're not a plant); The closest relative would be the mitochondria.
Muscle cells have more mitochondria because they require more energy to contract than skin cells.
A cells nucleus, mitochondria or a chloroplast may contain the DNA.
"muscle"
Cells with more mitochondria are typically found in tissues that require a lot of energy, such as muscle cells and liver cells.
Mitochondria, as they are responsible for producing energy in the form of ATP through cellular respiration. Cells that require a lot of energy, such as muscle cells or neurons, will have higher concentrations of mitochondria to meet their energy demands.
