Unit 3 Chemistry Of Life Essay
Mr. Johnson
Honors Biology
Unit 3: Chemistry of Life Study Guide 1) What are the major components of an atom?
Proton, Electron and Neutron 2) Which Subatomic particle is most important to biological systems?
The most important subatomic particle to biological systems is 3) Be able to indentify various Chemicals bonds. 4) How does polarity of water make it an excellent solvent?
The polarity of water is caused by the electro negativity of the oxygen atom, so electron density is drawn towards it from the hydrogen’s thus leaving a permanent dipole 5) How are the various properties of water utilized in biological systems?
6) Be able to analyze the components of a pH scale.
7) Why is Carbon the building block of all life on Earth? …show more content…
This ability makes it the building block of life as we know it. 8) Identify Products in a chemical equation 9) Identify reactants in a chemical equation 10) The definition of organic molecule is An organic compound is any member of a large class of chemical compounds whose molecules contain carbon. 11) Four macromolecules are Carbohydrates, Proteins, Lipids and Nucleic Acid. 12) Carbohydrates- Short term energy( sugar ) and structural energy
Lipids- Long term energy storage and insulation
Proteins- Build or repair tissue and catalyze chemical reactions
Nucleic Acid- storage of heritable information and helps make protein 13) Carbohydrates- Grains and Fruits
Lipids- Butter and Oil
Proteins- Meat, eggs, soybeans
Nucleic Acid- Nucleus of living cells 14) Carbohydrates- Plants: cellulose Animals:Glycogen
Lipids- Cell Membranes: Phospholipids
Proteins- Humans: Skin, Hair, Nails , Organs.. Enzymes: make or break molecules
Nucleic Acid- DNA: Genetic Blueprint… RNA: Copies
