The mitochondria are organelles that provide, energy for the cells. They convert energy into forms that are usable by the cell. Located on the cytoplasm of the cell. The mitochondria are involved in cellular respiration, which generates fuel for the cells activities. The Mitochondria is used for the splitting of glucose through pyruvate.
-Are striated and tubular
-are usually attached to the bones of the skeleton.
( Ex. Biceps, Triceps, long muscles)
-Are not striated
-have one nucleolus
-Are formed on the walls of Organs
( Ex. Vessels, Arteries, walls of Organs)
-Are striated and tubular and are branched
-Have one nucleolus
-Are formed on the walls of the Heart
The skeleton muscles consists of tendons, a heavy band of tissues that each end is attached to, bone to bone. Muscle fibers are organized into large bundles. The muscle consists of clusters of such bundles of muscle fibers. Blood vessels run between the muscle fibers.
Hierarchy of muscles:
-another band of muscle fiber
1) The primary function of ATP is to transfer from one location to another. At rest the muscle tends to produce more ATP than it needs, the excess ATP combines with creatine, (amino acids.)
Creatine phosphate + ADP-------------------- > creatine + ATP
2)During contraction of the muscles, the cross bridge breaks down ATP producing ADP. The energy ADP recharges to reverse the reaction.
ADP+ Creatine phosphate <----------- ATP +Creatine
This respiration takes place in the mitochondrion, glycogen and fat is stored in the muscles of the cell. Myoglobin an oxygen carrying molecule that is similar to hemoglobin is synthesized in muscle cells. Its presence accounts for its reddish color of the skeletal muscle.
Like creatine phosphate breakdown, supplies ATP without consuming oxygen. If there is an accumulation of lactate in a muscle fiber, the acidity concentration increases causing more fatigue in the performance. Lack of calcium ions are shown that’s why using creative in workout is necessary.
