Question

ed on Buffers Buffers are defined as any substance that resists cha ges in pH. In the human body Bicarbonate is the most critical buffer. Bicarbonate will be discussed in much greater detail in Bio192 during our discussion of the respiratory system and urinary systems Now that we have discussed basic chemistry, the way in which atoms interact with each other. For Anatomy and Physiology the most important chemistry is the assembly of atoms into complex biological macromolecules (macro large). The study of complex biological macromolecules is called Biochemistry Organic vs Inorganic Molecules: As a general rule, organic molecules are defined as molecules that contain molecules are those that do contain Inorganic Classes of Organic Matter: All 4 of these classes of biological macromolecules are repeating subunits of reactions called monomers in a chemical reaction callec that are made up of . These monomers are joined together through chemical Polymers can then be broken down back into 1. Carbohydrates . Contain carbon, hydrogen and oxygen in a 1:2:1 ratico . Primary Function: Short term energy suppl

Explanation / Answer

Image 1

Organic v/s Inorganic molecules

1. carbon and hydrgen (May have nitrogen and phosphorous as well)

2. carbon or hydrogen (not both) and other as well.

Classes of organic matter

1. Carbohydrates

2. Proteins

3. Nucleic Acids

4. Lipids

Blank 1: polymers

Blank 2 monomers

Blank 3: Dehydration Synthesis

Blank 4: Hydrolysis

1. Carbohydrates

a) monomers of - monosaccharides

eg. Glucose, galactose, fructose

b) two linked monomers are called: disaccharides

eg. maltose sucrose lactose

c) chains of monomers are called: polysaccharides

eg. starch, glycogen, cellulose

2. Ans: Lipids

a) Are hydro ans: carbons....

b) comprised of monomers of fatty acid and gylcerol

c) fatty acid= a carboxylic acid consisting of hydrocarbon chain and terminal carboxyl group

d) saturated: the entire chain has predominantly all single bonds.

monounsaturated: has atleast one double bond or triple valence molecule.

4 major types:

1. triglycerides

Three molecules of fatty acid bound to one molecule of gylcerol. It includes fats and oils.

2. phospholipids

Major component of the cell membrane. Only 2 fatty acids attached to the glycerol while the third fatty acid holds the phosphate group which is in turn bonded to alcohol.

3. Sterols

The most common example being cholesterol. These molecules hold the cell membrane and very complex molecules in structure.

4. wax

they are esters formed between long chain alcohol and saturated fatty acids. Human skin, fur, feathers naturally produce wax which is waterproof coating. It also has pathogenic property in some bacteria.
