The Facts of Life: Chemistry Is the Logic of Biological Phenomena

1. All are distinctive properties of living systems EXCEPT:

• Living organisms are relatively simple.
• Biological structures play a role in the organism's existence.
• The living state is characterized by the flow of energy through the organism.
• Living organisms are highly organized.
• Living organisms are actively engaged in energy transformation.

- ANSWER: a

• Even though the building blocks have fairly simple structures,

macromolecules are exquisitely organized in their intricate three-dimensional

architecture known as:

• configuration.
• conformation.
• sequence.
• Lewis structure.
• structural maturation.

- ANSWER: b

• All of the following activities require the presence of ATP or NADPH

EXCEPT:

• osmoregulation.
• biosynthesis.
• movement of muscles.

• | P a g e

• light emission.
• none, they are all energy-requiring activities.

- ANSWER: e

• Which are the four most common elements in the human body?
• hydrogen, calcium, oxygen and sodium
• hydrogen, oxygen, iron and carbon
• hydrogen, oxygen, carbon and nitrogen
• oxygen, carbon, iron and nitrogen
• oxygen, silicon, calcium and nitrogen

- ANSWER: c

• What makes carbon such an abundant element in biomolecules?
• It can form up to five bonds by sharing its electrons.
• It forms only single bonds.
• It provides low bond energy.
• It forms stable covalent bonds by electron pair sharing.
• It does not usually bond to other carbons, allowing a more diverse

combination of elements.

- ANSWER: d

• The major precursors for the formation of biomolecules include all

EXCEPT:

• nitrate and dinitrogen.
• water.
• carbon dioxide.

• | P a g e

• ammonium ion.
• none, all are major precursors.

- ANSWER: e

• From the major precursors, the complex biomolecules are made in which

sequence?

• metabolites, building blocks, macromolecules, supramolecular complexes
• macromolecules, building blocks, metabolites, supramolecular complexes
• building blocks, macromolecules, supramolecular complexes, metabolites
• metabolites, macromolecules, building blocks, supramolecular complexes
• metabolites, building blocks, supramolecular complexes, macromolecules

- ANSWER: a

• The structural integrity of supramolecular complexes (assemblies) of

multiple components are bonded to each other by all of the following forces

EXCEPT:

• covalent bonds
• van der Waals forces
• hydrogen bonds
• hydrophobic interactions
• ionic interactions

- ANSWER: a

• Organelles have what three attributes?
• Only in prokaryotic cells, membrane bound, have a dedicated set of tasks.
