Answer:
Acetylcholine
Explanation:
Acetylcholine is an organic chemical that functions in the brain and body of many types of animals and humans as a neurotransmitter.
Answer:
Skeletal muscle stores glycogen because it is a heavy consumer of energy.
Explanation:
Skeletal fiber contractions are based on different physiological and biochemical phenomena that happen in every cell and that need an amount of energy to occur. During muscle contraction, <em>myosin binds to the uncovered actin-binding sites, producing littles power strokes that, continuously, lead to muscle contraction</em>. To make this process possible, the muscle needs energy.
Glycogen is a very important energetic reserve polysaccharide for animals. It is stored in the liver and muscles, and when the organism needs energy it degrades glycogen into glucose, which is an available form for the metabolism. In the liver,<em> glycogen</em> is used to maintain constant levels of <em>blood glucose</em>. While in muscles, glycogen plays an important role in the glucose storage as a source of energy, needed and used only for contraction.
During muscle contraction, ATP molecules obtained from glucose are split to ADP and inorganic phosphate.
The claim that extant great apes and Miocene apes have an uninterrupted fossil record in Africa is not currently supported.
<h3>What started the evolution of primates?</h3>
The early primates most likely descended from a small, nocturnal, insectivorous mammal. Tree shrews and colugos, sometimes known as flying lemurs, are the two species that are most similar to primates. A living illustration of early primates or primate ancestors' appearance is the tree shrew.
<h3>Why are we not still descended from apes?</h3>
Like chimpanzees, we did not develop from a contemporary living primate. Our common ancestor with apes, who lived and perished in the distant past, is where we evolved and descended from. This indicates that we share ancestry with other apes.
