Cellular Respiration: Unraveling the Energy-Producing Process
Words • 581
Pages • 3
Cellular respiration is a fundamental biological process that takes place within the cells of living organisms. It is a series of complex chemical reactions that converts glucose and oxygen into carbon dioxide, water, and adenosine triphosphate (ATP) – the currency of energy in cells. This vital process is essential for the survival and functioning of all living organisms, from tiny microorganisms to complex multicellular beings like humans. At its core, cellular respiration is an aerobic process, meaning it requires oxygen…...

Words • 582
Pages • 3
Duchenne's muscular dystrophy is the result of a defective gene on the X chromosome. This gene is responsible for production of the muscle protein dystrophin. Dystrophin is an integral pan of the dystrophin-glycoprotein complex which bears the brunt of the force generated during muscular contraction. When dystrophin is not produced, the dystrophin»glycoprotein complex (DCG) is not present. Absence of the DCG leads to tears in the muscle membrane because the muscle membrane bears the force of muscular contraction alone. Tears…...
