Chapters 1-3Introduction and Chemistry

Introduction to Biology• Name the domain that includes prokaryotic cells that live in extreme

conditions of pH, salinity and temperatures.• Look in the internet for the wording. Using the binomial nomenclature

system give the scientific names of:– Humans– Red tie– Button mushroom– Tomato

• Build in the hierarchy of organism from an atom to the biosphere, using man as the organism.

• Put in order– Kingdom – family – phylum – order – domain – genus – epithet - class

• Look at the picture and name the kingdoms

• List the properties of living things.• What is the importance of DNA and RNA?

Chemistry• What type of covalent bond do you see in each of these molecules?

• What type of atoms do you see in the next drawings?

• Which of the two drawings you see above is the anion and which is the cation?

• Look for the element P in the periodic table.– Name it – Give its atomic number– Give its atomic mass– How many electrons does it have in the last shell?– What is its valence?

• Find the reducing and oxidizing agents C6H12O6 + 6O2 6CO2 + 6H2O

• Name the physical and chemical properties of water.• Name the solvents and solutes in a cup of coffee.

• What is the difference between the terms hydrophilic and hydrophobic?

• Use the periodic table. How much does a mole of Maltose (C12H22O11) weigh?

• If the concentration is 0.2M, how many grams of maltose would you put in a liter of water?

• Which has a higher [H+] in it, a solution with pH 1 or pH 3?• If pH is 5, what is the concentration of OH- ions?• Name the types of isomers present in nature.• Give the monomer of a protein.

• Name the types of functional groups present in:– Ketones– Amino acids– Organic acids– Alcohol– Thiols– ATP

• Identify the functional groups

• Give the type of bond present in:– Carbohydrates– Proteins– Lipids– Nucleic acids

• Differentiate anabolism from catabolism• What is the difference between saturated and unsaturated fats?• Name and describe the 4 levels of protein structure.• Draw the mRNA product of this DNA strand
