  • Glycolysis is localized in what part of the cell?
    Cytosol
    Mitochondria
    Ribosomes
    Endoplasmic reticulum
  • When glucose is oxidized to two pyruvate molecules, the net number of ATP molecules produced by direct phosphate transfer is
    6
    2
    8
    4
  • NAD+ (nicotinamide adenine dinucleotide) is the hydrogen acceptor when
    A reduction produces a C-C bond
    An oxidation removes hydrogen to produce a C=O bond
    A reduction produces a C=O bond
    An oxidation produces a C=C bond
  • During anaerobic exercise, the process of lactate formation in the muscle,
    Does not form CO2
    Replenishes NAD+ for use in glycolysis
    Converts Pyruvate to Lactate
    All of these
  • In the process of glycolysis, glucose is converted to
    Ethanol
    Oxaloacetate
    Lactose
    Pyruvate
  • Under aerobic conditions, pyruvate produced in glycolysis can be converted to
    glyceraldehyde-3-phosphate.
    Acetyl coenzyme A
    fructose-6-phosphate
    lactic acid
  • The coenzyme primarily involved in activating two carbon units (acetyl groups) is
    ATP
    Coenzyme A
    FAD
    NAD+
  • In step 7 of glycolysis, ATP is generated when a phosphate group is transferred directly from 1,3-diphosphoglycerate to ADP in a process known as
    Oxidative phosphorylation
    Oxidation
    Transamination
    Substrate level phosphorylation
  • The portion of Coenzyme A that reacts with potential substrates is
    A C=O group
    a thiol group
    An alcohol group
    an acid group
  • Which of the following is true for the glycolytic pathway?
    All reactions involve trioses
    All reactions require ATP
    NO ATP is produced
    All reactions are catalyzed by specific enzymes
  • The Cori Cycle
    Utilizes glyconeogenesis in the liver
    Uses bloodstream to transport lactate from muscles to liver
    Uses bloodstream to transport glucose from liver to muscle
    All of these
  • The primary energy source for the brain is
    Fructose
    Amino acids
    Lactate
    Glucose
  • The final products of catabolic reactions are:
    Carbon dioxide, water and ammonia
    RNA and DNA
    lipids, oxygen and water
    Glucose, lipids and glycogen
