FIRST COURSE IN SYSTEMS
BIOLOGY 2ND EDITION PRACTICE
SET 2026 TESTED PROBLEMS AND
VERIFIED ANSWERS
◉ Reductionist approach. Answer: Studies isolated components with
high control; useful for mechanisms but limited real‑world relevance.
◉ Integrated approach. Answer: Examines whole organisms/systems
with less control but greater physiological relevance.
◉ Emergent properties. Answer: Properties of a system that cannot be
predicted by studying components alone.
◉ Energy distribution system. Answer: Interaction of adipose, muscle,
liver, gut, cardiovascular, and nervous systems.
◉ Genomics. Answer: Study of an organism's complete DNA set.
◉ Proteomics. Answer: Study of all proteins produced by a cell, tissue,
or organism.
◉ Metabolomics. Answer: Study of metabolites within a biological unit.
, ◉ Leptin paradox. Answer: Leptin increases fat oxidation in isolated
models but is ineffective clinically due to resistance and systemic
effects.
◉ VO₂ max limitation (whole body). Answer: Primarily limited by
cardiac output.
◉ VO₂ max limitation (single‑leg model). Answer: Limited by muscle
mitochondrial content.
◉ Control and Communication Network (CCN). Answer: Integrated
system coordinating all physiological functions.
◉ CCN components. Answer: CNS, PNS, endocrine system, support &
defense system.
◉ CCN properties. Answer: Always on, distributed, redundant,
chemically based communication.
◉ Mind-body connection. Answer: Thoughts and emotions are
biochemically mediated.
◉ CCN and health. Answer: Integrates genetics, lifestyle, and
environment to determine health or disease.
