4) In the lab you are extracting and enzyme called catalase
from a potato and want to use this enzyme to speed up a
reaction in the lab. The potato usually grows in soil pH of
5.5 and a temperature of 18 °C. You extract the enzyme and
run a reaction with it in the following conditions. pH 9.5
and temperature = 20 °C. What can be said about the
enzymes activity? If activity is low how would you correct
this issue? Please explain in detail and in your own words.
The mutated form of hemoglobin (hemoglobin S, or HbS) in sickle-cell anemia results from
the replacement of a glutamate residue by a valine residue at position 6 in the ß chain of the
protein. Normal hemoglobin is designated HbA.
Under conditions of low [O₂], HbS aggregates and distorts the red blood cell into a sickle
shape. See image of eight aggregated HbS molecules. Sickled red blood cells are relatively
inflexible and may clog capillary beds, causing pain and tissue damage. The sickled red
blood cells also have a shorter life span, leading to anemia.
Which amino acids would be expected to produce a similar sickling effect if substituted for Val at position 6?
arginine
phenylalanine
Aggregate of HbS molecules
lysine
leucine
alanine
Sickling occurs in deoxyhemoglobin S but not in oxyhemoglobin S. Oxyhemoglobin has a small, hydrophobic pocket in a B

The name carbohydrate comes from the fact that many simple sugars have chemical formulae that look like water has simply been added to carbon. (The suffix hydrate from the Greek word hydor ("water") means "compound formed by the addition of water.")
The actual chemical structure of carbohydrates doesn't look anything like water molecules bonded to carbon atoms (see sketch at right). But it is nevertheless possible to chemically extract all the hydrogen and oxygen from many simple carbohydrates as water, leaving only carbon behind. If you search the Internet for "reaction of sulfuric acid and sugar" you will find some impressive videos of this.
Suppose you had
300.g
of ordinary table sugar, which chemists call sucrose, and which has the chemical formula
C12H22O11
. Calculate the maximum mass of water you could theoretically extract. Be sure your answer has a unit symbol, and round it to the correct number of significant digits.
