please solve DD3.2 part 2
DD3.2b Part 1: Open your refrigerator. There is water in some of the things you see. Choose and explain 2 examples of hydrophilic and hydrophobic substances and what those properties "cause" DD3.2b Part 2: Water is a solvent. It can dissolve lots of stuff. Some of that "stuff is very important for your body to function. Pick 5 substances and tell me where they originate from, their journey from your mouth to the blood stream, and what use they are for the bodyThis sounds like a lot .. If you do a lot you get a lot... of extra credit If you do not do so much, DD3.3- Part 1: Knowing why things are a base, or an acid, how can water be both? Explain.Explanation / Answer
The food consumed contains nutrients that are dissolved in water. The carbohydrates are sugars are water soluble. The polysaccharides are broken down to simple sugars or monosaccharides by the reaction with water. The carbohydrates provide immediate energy to the body in the form of glucose.
Proteins are amphipathic molecules and most of them are water dissoluble. The proteins are building blocks of muscle and perform variety of functions in body such as muscle building, wound healing, tissue repair, transport of substances in to cells and tissues and signal transmission and inter and intracellular communication etc. Proteins are provide energy.
Some of the lipids are hydrophilic or water attractant and can be hydrolyzed. The lipids provide energy, transport substances and regulate the body temperature.
The salt contains sodium and chloride. These are minerals that are dissolved in water. Other minerals like carbon, hydrogen and oxygen react with water. These ions and minerals maintain electrolyte balance in the body.
The water soluble vitamins such as B complex and vitamin C are important cofactors in metabolic activities and many of them act as coenzymes. The vitamin C is important for wound healing and exhibits antioxidant activity.
The salivary enzymes such as amylase, protease and lipase act on food consumed and breakdown the carbohydrates, proteins and lipids into simple substances that enter into stomach after meachnical processing of food by biting and chewing in mouth. Once the partially digested food enters the stomach, further the mechanical and chemical digestion (by enzyme activity, the enzymes are released from stomach and pancreas) processes are carried out. Finally, the end products of digestion such as monosaccharides, amino acids and fatty acids are absorbed in small intestines. The remaining waste is eliminated out of the body.
