NOUTCHA DATE : 7TH MARCH, 2013 INTRODUCTION Respiration is one of the characteristics of ALL LIVING THINGS. In the simplest terms, "respiration" simply means "breathing"
degradation of connective tissue occurs during short duration exposure to microgravity (Vailas, et al., 2001). Furthermore, the bone loss that occurs in microgravity has been estimated by various calcium-balance studies and excretion studies. An increased urinary excretion of calcium, hydroxyproline & phosphorus has been noted in the first 8 to 10 days of microgravity suggestive of increased bone re-absorption (Cena, Sculati, & Roggi, 2003). Rapid increase of urinary calcium has been noted after
maltose | Energy source | Sucrose is table sugar, lactose is present in milk; all must be broken down to monosaccharides before absorption | Polysaccharides | Glycogen | Storage of glucose molecules | Glycogen is found in animal cells; other starches and cellulose in plant cells | Lipids – also contain carbon, H, and oxygen but because they have relatively less oxygen than Carbs, the ratio does not approximate 1:2:1. * May contain small quantities of other elements such as phosphorus, nitrogen
