Below are sample questions representative of the exercises included on this worksheet and related 10.44 Aerobic versus Anaerobic Pathways skill assessments:

Problem 1Difficulty: Mastery

Use the decision-tree model. Which branch correctly identifies alcoholic fermentation?

AOxygen present -> ETC active -> O2 accepts electrons -> water forms.

BNo oxygen -> ETC active -> nitrate accepts electrons -> no ethanol forms.

CNo oxygen -> pyruvate accepts electrons -> lactate forms with no CO2.

DNo oxygen -> no electron transport chain -> acetaldehyde accepts electrons -> ethanol and CO2 form.

Solution & Explanation:Alcoholic fermentation occurs without oxygen or an electron transport chain, uses acetaldehyde as the electron acceptor, and produces ethanol and carbon dioxide.

Problem 2Difficulty: Mastery

Use the ecosystem energy-flow model. Which statement best explains why anaerobic pathways matter even with lower ATP yield?

AThey always replace photosynthesis in oxygen-rich habitats.

BThey produce more ATP than aerobic respiration in every decomposer.

CThey allow energy transfer and matter cycling in oxygen-poor habitats where aerobic respiration is not possible.

DThey eliminate the need for glucose or other organic molecules.

Solution & Explanation:Anaerobic pathways are important because they let organisms metabolize organic matter in oxygen-poor environments, supporting ecosystem matter cycling despite lower energy yield.

Problem 3Difficulty: Mastery

A toxin damages the inner mitochondrial membrane but leaves cytosolic enzymes intact. Which result is most likely in a glucose-fed animal cell?

AAerobic ATP production increases because the membrane is unnecessary.

BAerobic ATP production decreases, and fermentation may partly maintain glycolytic ATP.

CThe cell makes ethanol and CO2 as its only option.

DGlycolysis stops because it occurs inside the inner mitochondrial membrane.

Solution & Explanation:The inner mitochondrial membrane is needed for electron transport and oxidative phosphorylation. Cytosolic glycolysis can continue if fermentation regenerates NAD+.
