AP Biology - Unit 3 comprehensive
Questions and Answers with Verified
Solutions
Question 1:
ATP
Answer:
(adenosine triphosphate) main energy source that cells use for most of
their work
Question 2:
ADP
Answer:
adenosine diphosphate; molecule that ATP becomes when it gives up
one of its three phosphate groups
Question 3:
,free energy
Answer:
Chemical energy available to do work
Question 4:
substrate level phosphorylation
Answer:
the enzyme-mediated direct transfer of phosphate from another molecule
(the substrate) to ADP
Question 5:
reduction
Answer:
Gain of electrons by a chemical reactant; any reduction is accompanied
by an oxidation.
,Question 6:
oxidation
Answer:
Relative loss of electrons in a chemical reaction; either outright removal
to form an ion, or the sharing of electrons with substances having a
greater affinity for them,
Question 7:
oxidized
Answer:
loses electrons
Question 8:
reduced
Answer:
, gains electrons
Question 9:
NAD
Answer:
nicotinamide adenine dinucleotide - a coenzyme that is an electron
carrier; NAD+ is oxidized, NADH is reduced
Question 10:
reducing agent
