, BIO101 – Saylor Exam Questions with
100% Correct Answers
Acetyl CoA - Answer ✓✓the combination of an acetyl group derived from pyruvic acid
and coenzyme A which is made from pantothenic acid (a B-group vitamin)
Activation Energy - Answer ✓✓the amount of initial energy necessary for reactions to
occur
Active site - Answer ✓✓a specific region on the enzyme where the substrate binds
Active transport - Answer ✓✓form of transport across the cell membrane that requires
input of cellular energy
Adaptation - Answer ✓✓The process of becoming adjusted to an environment; a
characteristic which helps an organism survive in a specific habitat.
Allosteric inhibition - Answer ✓✓the mechanism for inhibiting enzyme action in which a
regulatory molecule binds to a second site (not the active site) and initiates a
conformation change in the active site, preventing binding with the substrate
Amphipathic - Answer ✓✓describes a molecule that exhibits a difference in polarity
between its two ends, resulting in a difference in water solubility
Anabolic - Answer ✓✓describes the pathway that requires a net energy input to
synthesize complex molecules from simpler ones
Applied Science - Answer ✓✓a form of science that solves real-world problems
Asexual Reproduction - Answer ✓✓Reproduction involving only one parent; occurs
without a fusion of gametes; produces offspring that are all genetically identical to the
parent.
ATP Synthase - Answer ✓✓a membrane-embedded protein complex that regenerates
ATP from ADP with energy from protons diffusing through it
Basic Science - Answer ✓✓science that seeks to expand knowledge regardless of the
short-term application of that knowledge
Bioenergetics - Answer ✓✓the concept of energy flow through living systems
Catabolic - Answer ✓✓describes the pathway in which complex molecules are broken
down into simpler ones, yielding energy as an additional product of the reaction
