Question
Chapter 14, Problem 3P
Interpretation Introduction
Interpretation:
The reason for the GTPase activity of G proteins to be crucial for the functioning of a cell needs to be explained. A theory for G proteins to be not evolved in the hydrolysis of GTP as a catalyst needs to be proposed.
Concept introduction:
GTPase activities are performed by the GTPases which are the families of hydrolase enzymes.
G proteins are the kind of proteins which act as molecular switches inside the cells. They transmit signals from outside to interior.

1. Suppose an enzyme (MW = 5,000 g/mole) has a concentration of 0.05 mg/L. If the
kcat is 1 x 10 s, what is the theoretical maximum reaction velocity for the
enzyme?
A) 1050 µM/s.
B) 100 µM/s.
C) 150 μM/s.
D) 105 μM/s.
In 1956, E. P. Kennedy and S. B. Weiss published their study of membrane lipid phosphatidylcholine (lecithin) synthesis in rat
liver. Their hypothesis was that phosphocholine joined with some cellular component to yield lecithin. In an earlier experiment,
incubating 32 P-labeled phosphocholine at physiological temperature (37 °C) with broken cells from rat liver yielded labeled
lecithin. This became their assay for the enzymes involved in lecithin synthesis.
Determine the optimal pH for this enzyme and characterize the enzyme activity at different pH values.

The researchers then centrifuged the broken cell preparation
to separate the membranes from the soluble proteins. They
tested three preparations: whole extract, membranes, and
soluble proteins. Table 1 summarizes the results.

- Researchers isolated an unknown substance, X, from rabbit muscle. They determined its structure from the following observations and experiments. (a) Qualitative analysis showed that X was composed entirely of C, H, and O. A weighed sample of X was completely oxidized and the H2O and CO2 produced were measured. This quantitative analysis revealed that X contained 40.00% C, 6.71% H, and 53.29% O by weight. (b) The molecular mass of X, as determined by mass spectrometry, was 90.00 atomic mass units (u). (c) Infrared spectroscopy showed that X contained one double bond. (d) X dissolved readily in water, and the solution demonstrated optical activity when tested in a polarimeter. (e) The aqueous solution of X is acidic.
