• Electron transport chain

• Calvin cycle

• Glycolysis

What is the primary structure of a protein?

• Spiral sequence of amino acids

• Random sequence of amino acids

• Linear sequence of amino acids

• Circular sequence of amino acids

What are the building blocks of nucleic acids?

• Lipids

• Carbohydrates

• Amino acids

• Nucleotides

Which process in cellular respiration produces the most ATP?

• Citric acid cycle

• Fermentation

• Oxidative phosphorylation

• Glycolysis

What is the Michaelis-Menten equation used for in enzyme kinetics?

• Calculating the pH of a solution

• Describing the rate of enzymatic reactions by relating the reaction rate to the concentration of substrate.

• Determining the color of a reaction mixture

• Estimating the volume of a gas produced

In which organelle does cellular respiration take place?

• cytoplasm

• nucleus

• mitochondria

• endoplasmic reticulum

What is the function of helicase in DNA replication?

• Joins the Okazaki fragments

• Unwinds the double-stranded DNA

• Adds nucleotides to the growing DNA strand

• Proofreads the newly synthesized DNA

What is the role of coenzymes in metabolic pathways?

• Coenzymes have no role in metabolic pathways.

• Coenzymes are only found in non-metabolic processes.

• Coenzymes inhibit enzymes in metabolic pathways.

• Coenzymes assist enzymes by carrying chemical groups between enzymes in metabolic pathways.

• Alpha helices and beta sheets

• Phi structures and psi bonds

• Delta helices and omega sheets

• Random coils and gamma strands
