Question
Chapter 4, Problem 56TQ
Summary Introduction
To review:
The reason for the reduction of free energy of hydrolysis of ATP in the absence of Mg2+ (magnesium ion) from –35.7 kJ/mol (kilo Joule per mole) to –31 kJ/mol(∆Go [free energy change]) in the presence of 5 mM (millimolar) Mg2+ .
Introduction:
ATP (adenosine triphosphate) in cells exists in different forms. The four main forms of ATP are ATP4-, HATP3-, H2ATP2-, MgHATP-, and Mg2ATP. Free energy of the hydrolysis of ATP in the system is –35.7 kJ/molin the absence of magnesium ions.

Question 4.
Diabetes mellitus possesses a serious health challenge worldwide and there has been an
increased awareness for self-monitoring and point of care testing. The development of self-
monitoring of blood glucose (SMBG) is probably the most important advance in controlling
diabetes since the discovery of insulin.
a) Dextrostix, the first glucose meter was invented by Ernie Adams. Briefly discuss.
b) There are three principles of enzymatic reactions, utilized by current glucose meters.
Compare and briefly discuss these three principles.
