In which stage of cellular respiration is acetyl-coA produced? - CORRECT ANSWER Glycolysis
What is an autotroph? - CORRECT ANSWER An organism that utilizes light energy or inorganic
compounds to meet their energy requirements
The citric acid cycle is considered a cycle because __________. - CORRECT ANSWER the last product is
used in the first reaction to start the cycle over again
Which of the following depicts the correct order of how molecules move through cellular respiration? -
CORRECT ANSWER Glucose ->pyruvic acid -> acetic acid -> acetyl CoA
Which of the following is false about glycolysis? - CORRECT ANSWER It requires oxygen.
Which stage of cellular respiration yields the greatest amount of ATP? - CORRECT ANSWER Electron
transport chain
What is cellular respiration? - CORRECT ANSWER The aerobic harvesting of chemical energy from
organic fuel molecules
The preferred source of energy for glycolysis is ___________. - CORRECT ANSWER glucose
Match the following step of cellular respiration with the appropriate outputs. - CORRECT ANSWER Citric
acid cycle - 2 CO2, ATP, 3 NADH, FADH2
Which molecules can be broken down to generate ATP? - CORRECT ANSWER
Glucose,Fats,Proteins,Glycerol
= All of the listed responses are correct.
, While serving as a visiting professor on the planet Freedonia, with infinite resources available to you,
you decide to try implanting mitochondria into alien bacterial cells that can perform only glycolysis.
Assuming your experiment is successful, what result would you predict? - CORRECT ANSWER An increase
in ATP yield per glucose molecule
A drug that blocks the electron transport chain would probably cause the organism to ___________. -
CORRECT ANSWER make insufficient ATP to survive
What is a true statement about cellular respiration? - CORRECT ANSWER It occurs in both producers and
consumers.
What do glycolysis and the citric acid cycle have in common? - CORRECT ANSWER They both produce 2
ATP
Not all of the energy harvested during the chemical breakdown of food molecules is captured and
stored in ATP. What happens to the rest of the energy? - CORRECT ANSWER It is released as heat.
What is the correct order of cellular respiration? - CORRECT ANSWER Glycolysis -> citric acid cycle ->
electron transport chain
What is the role of fermentation in muscle metabolism? - CORRECT ANSWER Fermentation ensures a
steady supply of NAD+ for proper glycolytic functioning during periods of low oxygen levels in muscles.
Which stage of cellular respiration takes place in the cytosol? - CORRECT ANSWER Glycolysis
Why are protons (H+) pumped across the inner mitochondrial membrane? - CORRECT ANSWER Their
movement back across the membrane generates ATP.
Which of the following allows for ATP to be produced with the electron transport chain? - CORRECT
ANSWER H+ concentration gradient
