CAMPBELL BIOLOGY 12TH EDITION CHAPTER 9 QUESTIONS WITH
COMPLETE SOLUTIONS VERIFIED
Are Cellular respiration and fermentation Catabolic or Anabolic? - CORRECT ANSWERS-
Catabolic
Arrangement of atoms represents? - CORRECT ANSWERS-potential energy
Energy enters as __ and exits as __ - CORRECT ANSWERS-light and heat
Inner membrane of the mitochondrion is the site of? - CORRECT ANSWERS-electron transport
and chemiosmosis
Which process occurs in the inner membrane of the mitochondrion? - CORRECT ANSWERS-
oxidative phosphorylation
some ATP is formed directly by glycolysis and citric acid cycle by what process? - CORRECT
ANSWERS-substrate-level phosphorylation
What happens to glucose during glycolysis? - CORRECT ANSWERS-it splits into three carbon
sugars, smaller sugars are oxidized and rearranged to form two molecules of pyruvate
the cell invests ATP to provide activation and energy by phosphorylating glucose, this requires 2 ATP per
glucose - CORRECT ANSWERS-energy investment phase
ATP is produced by substrate-level phosphorylation and NAD+ is reduced to NADH by electrons released
by oxidation of glucose - CORRECT ANSWERS-energy payoff phase
photosynthesis generates ___and ___that mitochondria use as fuel for cellular respiration -
CORRECT ANSWERS-oxygen; organic molecules
some of energy released is to do ___ while the rest goes out as ___ - CORRECT ANSWERS-
work; heat
, Catabolic Metabolic Pathways release - CORRECT ANSWERS-Energy stored in complex organic
molecules
Fermentation - CORRECT ANSWERS-A partial degradation of sugars that occur without the
use of oxygen.
Cellular Respiration - CORRECT ANSWERS-consumes oxygen as a reactant to complete the
breakdown of molecules
In eukaryotic cell, where does cellular respiration occur - CORRECT ANSWERS-mitochondria
Catabolism of glucose is - CORRECT ANSWERS-exergonic
Redox reactions release ___ when electrons move closer to ___ ___ - CORRECT ANSWERS-
energy; electronegative atoms
Catabolic reactions transfer the ___ stored in food molecules, releasing energy that is used to synthesize
___ - CORRECT ANSWERS-energy; ATP
redox reactions (oxidation-reduction reactions) - CORRECT ANSWERS-Reactions that result in
the transfer of one or more electrons from one reactant to another
Oxidation - CORRECT ANSWERS-loss of electrons
Reduction - CORRECT ANSWERS-gain of electrons
Reduction reactions require both ? - CORRECT ANSWERS-donor and acceptor
When else can reduction reactions occur? - CORRECT ANSWERS-when transfer of electrons is
not complete but involves a change in degree of electron sharing in covalent bonds
