ECU Bio 1100 Exam 2 Practice
Questions and 100% Correct Answers
Phosphofructokinase ✅Enzyme that Catalyzes a reaction in which ATP is both a
substrate in the reaction and an allosteric inhibitor of the enzyme

Pyruvate Dehydrogenase ✅Uses Pyruvate as a substrate and products of the reaction
end up inside the mitochondrion.

Hexokinase ✅Transfers a phosphate from ATP to glucose during the energy
investment phase of glycolysis.

Pyruvate Kinase ✅Catalyzes a reaction with the products ATP and pyruvate

Glycolysis ✅Metabolic pathway with the net products of 2 ATPs, 2 NADHs and 2
pyruvates.

Oxidation of pyruvate to acetyl CoA ✅Metabolic pathway that releases 2 CO2
molecules for every glucose molecule fully catabolized during aerobic respiration.

Process carried out by a large enzymatic complex with products 2 NADH, 2 CO2 and 2
Acetyl CoA.

Krebs Cycle ✅Major metabolic pathway originally named after the product of following
chemical reaction: oxaloacetate + acetyl CoA ---> citrate

Process that releases 4 CO2 molecules for every glucose fully catabolized in cellular
respiration.

Glycolysis ✅Metabolic pathway that gets its name from the following reaction:
Fructose-1,6-bisphosphate --> glyceradehyde-3-phosphate + dihydroxyacetone
phosphate

Many enzymes are present in a cell, but in an inactive form until they are needed, or
can be inactivated when they are not needed. What, involving a covalent modification, is
a common mechanism for regulating enzymes? ✅Phosphorylation

Catabolic Reaction ✅Reaction or pathway in which the metabolic products have lower
free energy than the reactants

Anabolic Reaction ✅Reactant or pathway in which the metabolic products have higher
free energy than the reactants.

, Active Site ✅Location in an enzyme where the substrate for the reaction is bound.

Allosteric Inhibitor ✅A molecule that binds an enzyme at a location other than the
active site, resulting in a change of conformation that prevents the enzyme from binding
the intended substrate.

Competitive Inhibitor ✅A molecule that binds an enzyme at the active site, preventing
the enzyme from binding the intended substrate.

Activation Energy ✅All enzymes catalyze metabolic reactions by overcoming this.

Oxidation ✅This is what happens to an atom that loses electrons or ends up with
lesser share of electrons in a chemical reaction.

Reduction ✅This is what happens to an atom that gains electrons or a greater share of
electrons in chemical reaction.

First Law of Thermodynamics ✅In any process, the total energy of the universe
remains the same

Second Law of Thermodynamics ✅The entropy of an isolated system, not in
equilibrium, will tend to increase over time.

Exergonic Reactions ✅-Releases potential energy
-Free energy decreases
-Exothermic
-Catabolic

Endergonic Reaction ✅-Requires energy (ATP)
-Free Energy increases
-Endothermic
-Anobolic

Respiration ✅Glucose + O2 + ADP + Pi ---> CO2 + H2O + ATP

Fermentation ✅Glucose + ADP + Pi ----> Small organic molecules + ATP

Free Energy ✅the portion of a system's energy that can perform work

Isomeric Reaction ✅Chemical structure changes but the chemical formula remains the
same

-Refer to Glycolysis Exercise
