BIOC 3021 Exam 3 Pathways Questions With Complete
Solutions
Aerobic Glycolysis Correct Answers Breaking down glucose
into pyruvate, while generating ATP and NADH, providing both
immediate energy and metabolic intermediates for further
oxidative metabolism in the mitochondria.
Anaerobic Glycolysis Correct Answers Breaking down glucose
to generate ATP when oxygen is limited, producing lactate
instead of pyruvate as the final product.
Citric Acid Cycle (TCA) Correct Answers Oxidizes acetyl-
CoA to CO2, generates high-energy electron carriers.
Electron Transport Chain (ETC) Correct Answers Uses high-
energy electrons to pump protons, creating a gradient for ATP
synthesis.
Energy Cost of Fatty Acid Biosynthesis Correct Answers 1
ATP per malonyl-CoA, 2 NADPH.
Energy Cost of Fatty Acid Oxidation Correct Answers 2 ATP.
Energy Cost of Gluconeogenesis Correct Answers 4 ATP, 2
GTP.
Energy Cost of Glycogenesis Correct Answers 1 ATP.
Energy Cost of PPP Correct Answers 0 ATP.
, Energy Cost of Urea Cycle Correct Answers 3 ATP.
Fatty Acid Biosynthesis Correct Answers Builds fatty acids
from acetyl-CoA, stores energy as fat.
Fatty Acid Oxidation (β-oxidation) Correct Answers Breaks
down fatty acids into acetyl-CoA, generating NADH and
FADH2.
Gluconeogenesis Correct Answers Synthesizes glucose from
non-carbohydrate precursors to maintain blood glucose during
periods of low-carbohydrate intake or intense exercise.
Glycogen Breakdown Correct Answers Converts stored
glycogen into glucose-1-phosphate to supply energy or maintain
blood glucose levels.
Glycogen Synthesis Correct Answers Stores excess glucose as
glycogen.
Glycogenesis Correct Answers Occurs in liver, skeletal muscle,
and adipose tissue; converts glucose into glycogen.
Location of ETC Correct Answers Occurs in the inner
mitochondrial membrane.
Location of Fatty Acid Biosynthesis Correct Answers Occurs
in the cytosol.
Location of Fatty Acid Oxidation Correct Answers Occurs in
the mitochondrial matrix.
