Answer #1

Ans- Myocardium( cardiac muscle cells) contain high amount of Mitochondria.Mitochondria are the organelles that provide energy to the cells through ATP synthesis.That is why, these organelles are called as "Powerhouse of the cell".Since cardiac muscle cells require large amount of energy production to rhythmically expand and contract throughout life, their cells have high amount of the organelle Mitochondria.

Hence, the correct answer is mitochondria.

    26. Why did Jessie’s carnitine deficiency cause her to have abnormally low plasma glucose levels at the end of a fasting study, when compared to a healthy person who has fasted for the same length of time? In the absence of carnitine, the liver stores large amounts of glycogen; absorption of glucose to create these stores depletes blood glucose Carnitine acts as a hormone and stimulates glucose release from the liver; lack of carnitine results in loss of hepatic glucose...
