Cellular Respiration: Key Concepts
and Pathways2026 Exam Latest
Update 2026 (Questions and Answers-
Verified solutions
What is the function of the Electron Transport Chain (ETC)? - CORRECT ANSWERS The ETC
is involved in cellular respiration, facilitating the transfer of electrons and the production of ATP.
What are amphibolic pathways? - CORRECT ANSWERS Amphibolic pathways are metabolic
pathways that can function in both anabolism and catabolism.
Name two types of biomolecules that can enter the metabolic cycle. - CORRECT ANSWERS
Amino acids and fatty acids.
What is the role of glucose in metabolism? - CORRECT ANSWERS Glucose serves as a
primary fuel source for cellular respiration.
What are the building blocks of proteins? - CORRECT ANSWERS Amino acids.
What is a polymer? - CORRECT ANSWERS A polymer is a large molecule made up of
repeating subunits called monomers.
What reaction forms polymers from monomers? - CORRECT ANSWERS Condensation
reactions, also known as dehydration reactions.
What is hydrolysis? - CORRECT ANSWERS Hydrolysis is a reaction that breaks down
polymers into monomers using water.
, What are the three main types of carbohydrates? - CORRECT ANSWERS Monosaccharides,
disaccharides, and polysaccharides.
What is the base formula for carbohydrates? - CORRECT ANSWERS Cn[H2O]n, where 'n' is
the number of carbon atoms.
What is the primary function of lipids? - CORRECT ANSWERS Lipids serve as energy
storage molecules and are important for cell membrane structure.
What are the two main components of fats? - CORRECT ANSWERS A glycerol head and
fatty acid tails.
What distinguishes proteins from other macromolecules? - CORRECT ANSWERS Proteins
are made from amino acid monomers and perform a wide range of functions in the cell.
What are nucleic acids responsible for? - CORRECT ANSWERS Nucleic acids store genetic
information and provide instructions for protein synthesis.
What is the significance of the side chains in amino acids? - CORRECT ANSWERS The side
chains determine the unique properties of each amino acid, affecting their interactions in proteins.
What are the four levels of protein structure? - CORRECT ANSWERS Primary, secondary,
tertiary, and quaternary structures.
What is the role of carbohydrates in plants? - CORRECT ANSWERS Carbohydrates like
starch serve as energy storage in plants.
