Question

question 6 / 10
human heart cells require a constant release of energy to function continuously. which of these structures would be numerous in such cells to meet this demand?
a. plasma membrane
b. golgi apparatus
c. mitochondria
d. smooth er

Explanation:

Mitochondria are the powerhouses of the cell. They produce ATP (adenosine triphosphate), the energy currency of the cell, through cellular respiration. Since heart cells need a constant energy supply to function continuously, having numerous mitochondria ensures an adequate energy (ATP) production. The plasma membrane is mainly for regulating what enters and exits the cell. The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids. The smooth endoplasmic reticulum (smooth ER) is involved in lipid synthesis, detoxification, etc. None of these other organelles (plasma membrane, Golgi apparatus, smooth ER) are the primary sites for energy (ATP) production like mitochondria are.

Answer:

C. mitochondria
