Liberty University Biol 101 Quiz 5 Complete Solution Correct
Answer Key
Question 1 For most chemical reactions in the non-living world, the energy required to break
bonds in the reactant molecules
Selected Answer: a. and b. above
Question 2 In biosynthesis of a protein, energy for bonding amino acids together comes from
Selected Answer: the bonding reaction itself which gives off excess energy as it occurs.
Question 3 A producer organism is called a “producer” because it produces
Selected Answer: usable chemical energy.
Question 4 Physicists define energy as
Selected Answer: the ability to make specific changes occur.
Question 5 Reactants like hydrogen and oxygen molecules and are converted into a product like
water molecules in the course of
Selected Answer: a chemical reaction.
Question 6 Systems that convert energy from one form to another are
Selected Answer: not 100% efficient, the amount of useful energy decreases.
Question 7 In a long metabolic pathway, the multiple changes made to an initial reactant
molecule are entirely controlled by
Selected Answer: the active sites of the enzymes along the pathway.
Question 8 Energy-releasing reactions drive biosynthetic ones forward by contributing to a pool
of
Selected Answer: ATP molecules.
Question 9 If bacteria can get their energy for life from a single kind of chemical reaction, then
