The function of Mitochondria is in the generation of metabolic energy in eukaryotic cells. Mitochondria are responsible for most of the useful energy derived from carbohydrates and fatty acids. Assembly of Mitochondria thus involves protein encoded by their own genomes and translated within the organelle.
The answer would be “D,” as gravity is the force that keep all objects on Earth’s surface.
The layer of connective tissue, called the _perimysium_ , extends inward from the epimysium and separates the muscle tissue into small sections. these sections contain bundles of skeletal muscle fibers called _fascicles_ .
Additionally, bundles of contractile proteins called fibrils fill a muscle cell, called a fiber. Outside of each fiber, is the connective tissue endomysium. Bundles of fibers form fascicles, surrounded by perimysium. Bundles of fascicles and perimysium comprise the entire muscle organ, which is enclosed by epimysium.
The cell contains many nuclei containing DNA, so DNA synthesis and mitosis are taking place, but the cell is not undergoing cytokinesis.
