A starved subject is fed with radio labeled protein (with NT5 and C14). Breath, blood, urine and liver samples are analyzed for chemical composition. List the names of the
different compounds that will be labeled with radioactive carbon or nitrogen in the four different samples (state which compounds will be labeled with N15 and which will be
labeled with C'14).
Sample 1: Liver
Sample 2: Breath
Sample 3: Blood
Sample 4: Urine
Lactose in milk is hydrolyzed, absorbed through the intestines, and then utilized for
energy metabolism. Oligosaccharides that are not hydrolyzed in the digestive tract
cannot be absorbed nor used for energy. Choose the best explanation for why
these oligosaccharides would be necessary in human milk (or infant formula).
A) These oligosaccharides prevent weight gain
in infants.
B) These oligosaccharides absorb excess
energy, allowing infants to sleep.
C) These oligosaccharides train the digestive
tract to tolerate high levels of sugars, necessary
for a typical adult American diet.
D) These oligosaccharides provide fiber and
prevent constipation.
Fragments of the Murchison meteorite that crashed in 1969 have been analyzed by multiple laboratories. The Murchison meteorite broke apart and crashed on Earth 3.5 billion years ago, causing mass destruction. The 1969 data can be broken down into the following statements.
More than 86 amino acids and 14,000 molecular compounds have been detected.
The amino acids detected are a mixture of right-handed and left-handed molecules and include some known amino acids and several extraterrestrial amino acids.
The concentration ratios of known amino acids are similar to the ratios found on Earth.
The Murchison meteorite belongs to the class of meteorites that contain chemical signatures of the solar system around the time of the Sun’s formation.
Researchers in a lab recreated conditions similar to the Murchison meteorite strike in an environment comparable to Earth 3.5 billion years ago.
Which of the following statements predicts the most likely results from their simulation…
