|
Cardiac muscle cells have more structural proteins in their cytoplasm.

|
|
Cardiac muscle cells are located farther from areas where lipids are stored.

|
|
Cardiac muscle cells have a lower release rate of carbon dioxide into veins.
|
|
|
Cardiac muscle cells require a larger supply of energy released through respiration.

Detailed explanation-1: -Q. Cardiac muscle cells have a higher concentration of mitochondria than skeletal muscle cells. What does the difference in mitochondrial concentration most likely indicate about cardiac muscle cells compared with skeletal muscle cells? Cardiac muscle cells have more structural proteins in their cytoplasm.
Detailed explanation-2: -The heart muscle has a large number of mitochondria to provide sufficient energy. The heart muscle needs the energy to pump blood into the body. Pumping is promoted by mitochondria. The heart muscle is very active and continuously functioning, so it needs more energy.
Detailed explanation-3: -Cardiac muscle cells have more mitochondria, as they are more reliant on aerobic respiration than skeletal muscle.
Detailed explanation-4: -Mitochondria are highly present in cardiac cells due to the increased energy demands and are responsible for the daily production of approximately 6 kg of ATP through the process of oxidative phosphorylation (8) (Figure 1).
Detailed explanation-5: -Cardiac muscle has more mitochondria and depends less on a continual supply of oxygen than does skeletal muscle. Congestive heart failure means that the pumping efficiency of the heart is depressed so that there is inadequate delivery of blood to body tissues.
