Chapter 6.1, Problem 2TYK
Summary Introduction
Introduction:
Entropy is the increase in the randomness of a system that is present in the environment. The entropy is the measure of the system’s thermal energy that is present per unit temperature, which is unavailable for performing any useful work.

Coenzymes function to:
change the shape of enzymes, allowing different additional substrates to bind.
denature the enzyme, stopping the chemical reaction from occurring.
interact directly with enzymes, either enabling the reaction to occur or making the substrate-enzyme interaction more efficient.
dilate blood vessels, allowing more blood to flow, allowing more substrate to reach enzymes.
absorb excess hydrogen and hydroxide ions, keeping the pH relatively stable, so that reactions can occur most efficiently.
Which of the following will occur if there is an increase in enzyme or substrate concentration?
interfere with the reaction.
increase the rate of reaction.
decrease the rate of reaction.
not change the rate of product produced
reduce the rate of product produced.
The hydrolysis of ATP can occur via more than one pathway. Which one yields the most energy,
and what is involved?
ATP to ADP, 2 water molecules
ATP to AMP, 1 water molecule
ATP to AMP, 2 water molecules
ATP to ADP, hydride ion
ATP to AMP, hydride ion
