This textbook solution is under construction.
Students have asked these similar questions
a) Describe a specific chemical reaction that occurs within the human
body and state the name of the enzyme involved, the substrate(s)
of the reaction, and the specific product(s) formed.
b) Enzymes are not used up in chemical reactions. So, what exactly
does an enzyme do?
In your answer you should refer to activation energy.
c) Explain what is meant by the induced fit action of an enzyme,
referring to the role of the active site, and to the activation energy of
an enzyme-catalysed reaction.
Which of the following statements about enzymes are true? Choose all that apply.
Group of answer choices:
a) Enzymes are nonspecific
b) Enzymes speed up the rates of chemical reactions
c) Enzymes require a lot of energy to synthesize
d) Enzymes are not important in biological systems
E) Reactants in enzyme-catalyzed reactions are called substrates
F) Enzymes lower the activation energy of reaction
G) Enzymes change ∆G of reactions
H) One enzyme usually catalyzes many types of reactions
I answered for letters , B, E, anf F, and got a 1.5 out of 2, so I am missing one.
Thank You!
The movement of energy between living organisms is a matter of atoms, molecules and compounds being built into larger molecules or being broke into smaller ones. Reviewing the two equations for energy transference, which one is building energy?
6CO2 + 6H2O + energy --------> C6H12O6 + 6O2
C6H12O6 + 6O2 ---------> 6CO2 + 6H2O + energy
