Identify and describe basic tissue types.
Short essay
Imagine that you fell down in the garden and cut yourself on a dirty piece of metal. In a short essay, describe primary and secondary tissue repair, what is meant by the term “clean wound”, the role of nutrition in the healing process, and how scar tissue forms.
Explanation / Answer
As per chegg guidelines I have to answer one question. Rest of the questions kindly post separately.
2. Basic biological molecules are;
Carbohydrates, amino acids, protiens, lipids, nucleic acids.
1.Carbohydrates: They are also called as sugars. These are the compounds made up of carbon , hydrogen and oxygen in which hydrogen and oxygen occur in the ratio of 2:1 as in water . This gives them their name ,hydrates of carbon. They are chemically called as polyhedron aldehyde or keto nest. Carbohydrates are commonly called as saccharides or sugars as most of them are sweet in taste.
They are classified as monosaccharides which are simple sugars that are not hydrolysed furthur. Examples are glucose,fructose,galactose, mannose,ribose,deoxyribose etc.
Oligosaccharides; compound sugars formed by joining 2 to 10 monosaccharides units . Examples are maltose,sucrose, lactose etc.
Polysaccharides; complex long chain carbohydrates which are formed by polymerization of large number of monosaccharide units usually glucose. Examples are glycogen, cellulose, chitin , starch etc.
2. Amino acids : These are the organic compounds having both amino and carboxylic group.They are the building blocks of protiens.Twenty types of amino acids occur in protiens. They are called as standard amino acids or protien amino acids.
3. Protiens : protiens are high molecular weight organic compounds which are made by the polymerization of small units called amino acids . Thus protiens are long chain polymers made by joining of number of small units ,amino acids. Protiens serve important functions in the body. They are used as enzymes, hormones or antibodies. They carry respiratory gaseous. They form structural components of tissues and cells.
4. Lipids:Lipids are heterogenous group of fat and fat line substances which are insoluble in water but structuraloluble in non polar sOlvents like ether, acetone etc. These include a wide variety of compounds like cholesterol, pigments, phospholipids cutting, suberin etc.
5. Nucleic acids:Nucleic acids are long chain linear and unbranched macromolecules that are formed by the polymerization of large number of repeated units called nucleotides. Examples of nucleic acids recidivism are DNA which serves as genetic material in most of the organism's and RNA which serves as genetic material in some viruses and other functions within the cell.
