  1. Chemistry in Biology Section 4 The Building Blocks of Life • The number and the order in which the amino acids are joined define the protein’s primary structure. • After an amino acid chain is formed, it folds into a unique three-dimensional shape, which is the protein’s secondary structure, such as a helix or a pleat.

  2. Chemistry in Biology Section 4 The Building Blocks of Life • Nucleic acids are complex macromolecules that store and transmit genetic information. • Nucleic acids are made of smaller repeating subunits called nucleotides, composed of carbon, nitrogen, oxygen, phosphorus, and hydrogen atoms.

  8. A B C Chemistry in Biology Chapter FQ 2 Section 1Formative Questions What causes the overall charge of an atom to be zero? an equal number of protons and neutrons an equal number of protons and electrons an equal number of neutrons and electrons

  9. A B C D Chemistry in Biology Chapter FQ 3 Section 1Formative Questions What type of substance is water? a compound an element an isotope a mixture

  10. A B C D Chemistry in Biology Chapter FQ 4 Section 1 Formative Questions What provides the energy for all living processes? chemical bonds ionic compounds radioactive isotopes van der Waals forces

  11. A B C D Chemistry in Biology Chapter FQ 5 Section 2 Formative Questions Which is a chemical reaction? a match burning salt dissolving water boiling gasoline evaporating

  12. A B Chemistry in Biology Chapter FQ 6 Section 2 Formative Questions Which chemical reaction is endothermic?

  13. A B C D Chemistry in Biology Chapter FQ 7 Section 2 Formative Questions How does an enzyme increase the rate of a chemical reaction? It acts as a reactant. It reduces the amount of heat produced. It increases the amount of product. It lowers the activation energy.

  14. A B C D Chemistry in Biology Chapter FQ 8 Section 2 Formative Questions What occurs at the active site in the enzyme substrate complex? An exothermic chemical reaction takes place. Chemical bonds are broken and new bonds are formed. The enzyme gets used up in the reaction. The substrates provide energy for the enzyme.

  15. A B C D Chemistry in Biology Chapter FQ 9 Section 3 Formative Questions Why is water able to dissolve a wide variety of solutes? It acts as a catalyst. Its pH is neutral. It is a polar molecule. It is an ionic compound.

  16. A B C D Chemistry in Biology Chapter FQ 10 Section 3Formative Questions What type of bonds attracts water molecules to each other and to other substances? covalent bonds double bonds hydrogen bonds ionic bonds

  17. A B C D Chemistry in Biology Chapter FQ 11 Section 3 Formative Questions Which ion, when released in water, causes a solution to be basic? Cl– OH– H+ Na+

  18. A B C D Chemistry in Biology Chapter FQ 12 Section 3 Formative Questions What is the name for a substance that keeps the pH in cells within the 6.5 to 7.5 pH range? alkali antacid buffer neutralizer

  24. A B C D Chemistry in Biology Chapter FQ 18 Section 4Formative Questions Which biological molecule transports substances between cells? carbohydrate lipid nucleic acid protein

  25. A B C D Chemistry in Biology ? Chapter CAQ 1 Chapter Assessment Questions Look at the following figure. Determine what the upward curve represents. activation energy reactants products enzymes

  26. A B C D Chemistry in Biology Chapter CAQ 2 Chapter Assessment Questions Look at the energy levels in the atom. What is the maximum number of electrons energy level two can hold? 2 4 6 8

  27. Chemistry in Biology Answer: Chemical reactions require balance of mass. Therefore, the number of atoms of each element on the reactant side must equal the number of atoms of the same element on the product side. Chapter CAQ 3 Chapter Assessment Questions Explain why chemical equations must be balanced.

  28. A B C D Chemistry in Biology Chapter STP 1 Standardized Test Practice Which is a result of van der Waals forces? atoms sharing electrons table salt dissolving in water ionic compounds forming crystals water molecules forming droplets

  29. A B C D Chemistry in Biology Chapter STP 2 Standardized Test Practice What is true of this chemical reaction? Energy is not needed to start the chemical reaction. Heat and/or light energy are released in this reaction. The activation energy is greater than the energy released. The energy of the products and the reactants is the same.
