Cellular Respiration Correct answer-the metabolic processes whereby certain organisms
obtain energy from organic moelcules
Kilocalories Correct answer-the unit in which energy is measured
Redox Reaction Correct answer-A chemical reaction involving the transfer of one or more
electrons from one reactant to another; also called oxidation-reduction reaction.
Oxidation Correct answer-The loss of electrons from a substance involved in a redox
reaction.
Reduction Correct answer-any process in which electrons are added to an atom or ion (as
by removing oxygen or adding hydrogen)
NAD+ Correct answer-electron carrier involved in glycolysis
NADH Correct answer-the reduced form of NAD+; an electron-carrying molecule that
functions in cellular respiration
Electron Transport Chain Correct answer-a series of proteins in which the high-energy
electrons from the Krebs cycle are used to convert ADP into ATP
, AP Bio Unit 3 Test;Questions & Answers 100% Solved
Glycolysis Correct answer-first step in releasing the energy of glucose, in which a
molecule of glucose is broken into two molecules of pyruvate
Pyruvate Oxidation Correct answer-2nd step in cellular respiration occurs on the way to
the mitochondrial matrix. Pyruvate is oxidized into 1 CO2, 1 NADH, 1 acetyl-COA (2 carbons
attached to coenzyme A)
Citric Acid Cycle Correct answer-in cellular respiration, series of chemical reactions that
break down glucose and produce ATP; energizes electron carriers that pass the energized
electrons on to the electron transport chain
Oxidative Phosphorylation Correct answer-The production of ATP using energy derived
from the redox reactions of an electron transport chain.
Chemiosmosis Correct answer-A process for synthesizing ATP using the energy of an
electrochemical gradient and the ATP synthase enzyme.
Substrate-Level Phosphorylation Correct answer-The formation of ATP by directly
transferring a phosphate group to ADP from an intermediate substrate in catabolism.
Intermediates Correct answer-the compounds that form between the initial reactant,
glucose, and the final product, pyruvic acid
