    Part A

    Why is ATP required for glycolysis?

    ATP is used to convert DHAP into G3P.

    ATP is used to convert PEP into pyruvic acid.

    ATP makes it easier to break apart glucose into two three-carbon molecules.

    ATP is used to reduce NAD+ to NADH.

    Part B

    Glycolysis literally means

    Glyceraldehyde 3-phosphate (G3P)

    Pyruvic acid

    Glucose

    Part E

    Which of the following statements about glycolysis is true?

    Glycolysis is the main source of NADH in the cell.

    All cells perform glycolysis.

    Glycolysis produces glucose.

    Glycolysis is also called the Embden-Meyerhof pathway.

    Part D

    What is the fate of metabolites during respiration?

    They are reduced to from NADH and FADH2.

    They are rearranged to form GTP.

    They are oxidized completely to carbon dioxide and water.

    They are oxidized completely to form pyruvic acid.SubmitHintsMy AnswersGive UpReview Part

    Which of the following is true of aerobic respiration compared to anaerobic respiration?

    Aerobic respiration uses oxygen as a final electron (hydrogen) acceptor, whereas anaerobic respiration uses an organic molecule.

    Aerobic respiration and anaerobic respiration both require oxygen as a final electron acceptor.

    Aerobic respiration uses oxygen as a final hydrogen acceptor, whereas anaerobic respiration uses an inorganic molecule other than oxygen as the final electron acceptor.

    Aerobic respiration is less efficient than all forms of anaerobic respiration, producing less ATP and largerend-products.

    Microbiology Animation: Enzymes: Overview

    Part A

    Why do all enzymatic reactions need activation energy?

    Energy is needed for the enzyme to find its substrate.

    Energy allows only the substrate to bind.

    Energy is required by an enzyme so that it can be reused.

    Energy is required to disrupt a substrate’s stable electron configuration.SubmitHintsMy AnswersGive UpReview Part

    Part B

    What is meant by the statement “Enzymes are biological catalysts”?

    Enzymes produce products useful for biology.

    Enzymes speed up the chemical reactions in living cells.

    Enzymes produce biological organisms.

    Enzymes are products of biological systems.SubmitHintsMy AnswersGive UpReview Part

    Part C

    Why are enzymes important to biological systems?

    Enzymes are reuseable.

    Enzymes decrease the amount of activation energy required for chemical reactions to occur.

    Enzymes prevent unwanted chemical by-products from forming.

    Enzymes increase the energy barrier required of chemical reactions. SubmitHintsMy AnswersGive UpReview Part
