H 2 O Rate Of Reaction
1,374 words
Title: The Effects of Substrate Concentration and
Temperature on the Rate of Hydrolysis of the
Enzyme Trypsin. Abstract: Quantitative
measurements can relate both temperature and
substrate concentration to the enzymatic activity
of trypsin. By analyzing the data, it is suggested
that at BAPNA concentrations below those
corresponding to Vmax are rate limiting, as less
active sights are available for adhesion. The
values of Vmax and Km relate a temperate catalytic
efficiency of trypsin. The temper...

Specific Heat Boiling Point
1,047 words
The purpose of this lab was to determine the
specific heat of two different metals. In order to
do this, specific directions were executed in
order to discover the specific heat. First, we
needed to obtain and record the weight of the
Styrofoam calorimeter cup. Next, we filled the cup
2 / 3 full with cool tap water and recorded the
temperature of the water. After this was done, we
filled a glass beaker half full with water and
placed it on a hot plate in order to have the
water reach boiling poi...

... ial's and Methods The first experiment
involved examining the effect of temperature on
aerobic respiration of germinated pea seeds. The
students testing the effect of temperature, will
be divided into two groups. The first group is
Student Pair A. They will test the effect of 10 C,
20 C and 30 C temperatures on pea respiration
rate. The second group is Student Pair B. They
will test the effect of 40 C and 70 C temperatures
on pea respiration rate. For both groups, the
first procedure calls f...

Pieces Of Literature Metabolic Rate
1,092 words
Animal metabolism consists of the utilization of
nutrients absorbed from the digestive tract and
their catabolism as fuel for energy or their
conversion into substances of the body. Metabolism
is a continuous process because the molecules and
even most cells of the body have brief lifetimes
and are constantly replaced, while tissue as a
whole maintains its characteristic structure. This
constant rebuilding process without a net change
in the amount of a cell constituent is known as
dynamic equil...

Global Warming - Problem and Solution
(Environmental) There are many problems concerning
the environment. Pollution, destruction of the
rainforests, and the consumption of all of our
planet's natural resources are just a few. None of
these issues quite compare to the problem of
global warming. Global warming is a problem that
affects not just some people, but everything and
everyone. People must take action to stop global
warming and must realize the severity of this
problem before it is too lat...

... over yet, is nothing but a prelude to the
future. According to scientists, the effect of
global warming is behind the increase of killer
hurricanes. The periodicity of hurricanes in the
next hundred years is going to increase by 60 - 70
% according to recent studies. Its been noted the
formation of hurricanes is closely related to
weather conditions around the globe. In 1991 the
winters were particularly cold in Alaska and
Siberia, yet it was the same year when many
furious hurricanes, notab...

Annual Temperature Fluctuation Ideal Storage Temperature Wine

A cellar may be humble or grand, large or small.
But if it is to qualify for name, it must achieve
three things. It should be dark, it should be free
of vibration and, above all else, and it should
reduce both daily and seasonal temperature
variations to a minimum. Ideal Cellar Conditions
The siting, or placement, of your wine cellar
within your home is your first major decision.
There are four components of ideal cellar
conditions: an absolutely constant temperature,
varying between neither day...

The Global Warming Global Warming The relationship
between humans and the state of the ecosystem is
not only dependent upon how many people there are,
but also upon what they do. When there were few
people, the dominant factors controlling ecosystem
state were the natural ones that have operated for
millions of years. The human population has now
grown so large that there are concerns that they
have become a significant element in ecosystem
dynamics. One of these concerns is the
relationship bet...

Rate Of Reaction Bunsen Burner
2,301 words
For this investigation I am going to investigate
the effect of the concentration of an enzyme, in
this case Amylase, on the time taken for the
enzyme to fully breakdown the substrate, which in
this case is starch. The reason why these two
enzymes have to be used is because each enzyme is
designed specifically to break down only one
substrate as each enzyme is made of a protein that
causes it to be a specific shape, in this case the
enzyme Amylase can only break down starch to
dextrin. I am going...

Burning Fossil Fuels Natural Greenhouse Effect
3,312 words
The Greenhouse Effect The greenhouse effect, as
defined in the dictionary, is the effect produced
as greenhouse gases allow incoming solar radiation
to pass through the Earths atmosphere, but prevent
most of the outgoing infrared radiation from the
surface and lower atmosphere from escaping into
outer space. Even though this process occurs
naturally and has kept the Earths temperature
about 60 degrees Fahrenheit warmer than it would
otherwise be, current life on Earth could not be
sustained with...

Polar Ice Caps Rise In Sea Level

The Greenhouse Effect Issue Statement While some
people believe the earths climatic changes are due
to the fact that the universe is getting older,
others believe it is due to the greenhouse effect.
The greenhouse effect is a naturally occuring
phenomenon that is responsible for trapping heat
near the earths surface and keeping the planet
warm. It is called the greenhouse effect because
the way it works is similar to the way in which a
green house functions. In a greenhouse sunlight
passes throu...

Times Per Minute Body Temperature Falls Hibernation

Hibernation: Definition Hibernation is an
inactive, sleep like state that animals must go
and at least one bird enter during the winter.
Animals that hibernate shelter themselves from
harsh winter and reduce their need for food. Their
body temperatures are considerably lower, as well
as their heartbeat and breathing. The true
hibernator spends most of the winter in a state
close to death; in fact the animal may appear to
be dead. The body temperature is close to zero
degrees; the respiration is ...

Measuring Cylinder Reaction Rate

How concentration affects reaction rate. The aim
of this investigation is to see how the
concentration of a reactant in ratio to the
reactor affects the rate of a reaction. When
hydrochloric acid and Thiosulphate react together
sulphur is liberated this means that as the
reaction goes on the solution will become yellow
and will change from being transparent to
translucent to opaque. The sulphur is formed as a
solid but not in the usual precipitation way. Na 2
