Running Head: ACE BIOLOGY MODULE 3:4 1 Organic Macro-Molecules and Membranes Assignment 1.What is the most familiar way that atoms and molecules are held together? Covalent bonds. 2.How does the energy of a covalent bond compare to thermal energy at body temperature? The energy of a covalent bond is very high at 80 kilocalories per mole, compared to the thermal energy at body temperature, at 0.6 kilocalories per mole. 3.What is the significance of the energy level of covalent bonds for organisms? The energy level of covalent bonds for organisms is significant because the high energy level causes molecules to be able to survive over long periods of time and through different conditions 4.Is the delta charge on a polar molecule a full electronic charge? No 5.Is a hydrogen bond more or less energetic than a covalent bone? A hydrogen bond is less energetic than a covalent bond 6.In real life ( which diagrams cannot really show), what are the hydrogen atoms in water doing in relation to the oxygen atoms? In real life, the hydrogen atoms may be actually bouncing back and forth between the water and oxygen atoms. 7.Why does water not vaporize and become a gas at room temperature? Water does not vaporize at room temperature because the water molecules have a strong affinity for one another.
