1. Which of the following is a statement of the first law of thermodynamics?
A) The entropy of the universe is decreasing.
B) The entropy of the universe is constant.
C) Energy cannot be created or destroyed; it is conserved. It can, however, be transformed.
D) Energy is often destroyed but it can be created by certain cosmic anomalies.
2. Which of the following is true of metabolism in its entirety in all organisms?
A. Metabolism is only necessary during certain times of the day.
B. Metabolic activity does not occur when animals sleep.
C. Metabolism does not require enzymes to speed up the rate of reactions.
D. Metabolism consists of all of the energy transformation and chemical reactions that occur in an organism.
3. Which of the following is true for all exergonic reactions?
A) The products have more total energy than the reactants.
B) The reactions proceed with a net release of free energy.
D) The reactions are always rapid.
E) The reactions only occur in certain organelles called exergonomes.
4. A chemical reaction that has a positive AG is correctly described as what type of reaction?
A) endergonic.
B) exergonic
5. In a chemical reaction, the energy necessary to break the bonds of the reactants-that initial input of energy need to start a reaction whether or not it is spontaneous--is referred to as which of the following?
A) Energy of Endogenous Reactivity EEA
B). Activation energy EA
C) Free energy EF
6. What might account for the fact that a solution of only sucrose (a disaccharide) in a container at room temperature does not readily degrade to form a solution of monosacchari?e (i.e., fructose and glucose)? This is an exergonic reaction which is spontaneous.
A) the sucrose solution has less free energy than the two monosaccharides.
B) the hydrolysis of sucrose to monosaccharides is endergonic.
C) the activation energy barrier for this reaction cannot be overcome at room temperature or in the absence of the proper enzyme.
7.Both mitosis and meiosis are types of cell division; mitosis results in equational division of chromosomes and meiosis results in reduction division of chromosomes. Which type of cell division results in the production of haploid gametes in animals, and haploid spores in plants?
a) mitosis
b) meiosis
c) halitosis
d) precocious
8. The complete complement of an organism's genes-its repertoire of genetic material--is referred to as its:
a) genome
b) karyotype
c) gnome
