Answer:
b) When glucose is labeled on carbon #1, 0.1 mole of acetyl-CoA is radiolabeled
c) When glucose is labeled on carbons #2 and #6, 0.2 mole of acetyl-CoA is radiolabeled
e) When glucose is labeled on carbons #2 and 6, the carbonyl groups of half of the acetyl-CoA molecules are radiolabeled
f) When glucose is labeled on carbons #2 and 6, the methyl groups of half of the acetyl-CoA molecules are radiolabeled
Explanation:
When glucose undergoes glycolysis, it is converted into two molecules of pyruvate with carbon 1 to 3 forming the first molecule of pyruvate and carbon 4 to 6 the second molecule of pyruvate. The C-1 and C-6 of the glucose molecule becomes the methyl groups of each of the two molecules of pyruvate. The C-2 and C-5 of the glucose molecule forms the carbonyl carbon of each of the two pyruvate molecules. Each of the two pyruvate molecules undergoes further oxidation to yield acetyl-CoA with the carbonyl and methyl groups of pyruvate retained in the acetyl-CoA molecules.
Thus when 0.2 moles of glucose are labelled at C-1 and then C-2 and C-6 in each of the two experiments the following results are obtained:
When glucose is labeled on carbon-1, 0.1 mole of acetyl-CoA is radiolabeled since half of the two pyruvate molecules are obtained from C-1
When glucose is labeled on carbon-2 and carbon-6, 0.2 mole of acetyl-CoA is radiolabeled since the C-2 and C-6 of the glucose molecules forms a part of one of each of the two pyruvate molecules.
When glucose is labeled on carbons #2 and 6, the carbonyl groups of half of the acetyl-CoA molecules are radiolabeled since one of the two carbonyl groups of the two pyruvate molecules is formed from C-2 of glucose.
When glucose is labeled on carbon-2 and carbon-6, the methyl groups of half of the acetyl-CoA molecules are radiolabeled since one of the two methyl groups of the two pyruvate molecules is formed from C-6 of glucose.

If a person had not drunk any water for 8 hours before collecting a sample, would you expect his/her urine to have a high or low specific gravity? Why?
Answer:
The person’s urine will have a high specific gravity
Explanation:
A high specific gravity is characterized by an increased concentration of solutes in the urine of am individual. A low specific gravity is characterized by a low or decreased concentration of the solutes.This is usually due to dehydration as a result of environmental conditions or tedious physical activities.
This explains why a person who had not drank any water for 8 hours and is dehydrated before collecting a sample is thought to have a urine with a high specific gravity

Explanation:
Describe how protein functional groups can act as acid and base catalysts. How is it possible for a single amino acid side chain to function as both?
Answer:
By changing the transition state and pH of the medium
Explanation:
Enzymes are proteins that bind to their corresponding substrates at their active sites in order to form complexes that catalyze specific chemical reactions. A key feature of this process is the fact that both acid and base catalytic activities may be combined in the same reaction. The acceleration in the velocity of the enzymatic reaction due to the addition of acids and bases is known as acid–base catalysis, where the acid or base is not consumed during the reaction. For example, enzymes can partially transfer a proton to the medium, thus changing the transition state of the chemical reaction and also decreasing its pH.
In the image, the arrow Is pointing to a celestial object. Which attribute disqualifies the object from being a planet?
A. It appears to have no moons.
B. It is spherical in shape.
C. Its neighborhood is not clear.
D. It has horizontal bands on its surface.
The correct answer is C. Its neighborhood is not clear.
Explanation:
One of the key features of a planet is that it clears its neighborhood; this means the planet gravitational force is strong enough that there are no other celestial bodies on its orbit or next to it except by its moons or satellites. This does not occur in the image presented because there are smaller celestial bodies near to the main or bigger celestial body. This likely occurs if the celestial body is not big enough to clear its neighborhood, and therefore it is not a planet.
Which of the following reflects the relationship between the posterior and the anterior pituitary glands?A. Unlike the posterior pituitary, the anterior pituitary makes and releases its own hormones without input from the hypothalamus.B. One is always a little behind.C. The anterior pituitary is under the control of the hypothalamus but the posterior pituitary is not.D. Unlike the posterior pituitary, the anterior pituitary releases "releasing or inhibiting" hormones.E. The posterior pituitary releases neurohormones and the anterior pituitary releases hormones.F. They are both extensions of the hypothalamus.
Answer:
The correct answer is - option E.
Explanation:
The anterior and posterior pituitary glands are he two distinct lobes of the pituitary gland which is controlled by the hypothalamus. The anterior lobe of the master gland is receives its signals from the specific neurons of the hypothalamus known as parvocellular neurons and produces six hormones that release in to circulation by itself.
On other hand the extension of the hypothalamus or the posterior pituitary gland receives the neurohormones from the hypothalamus such as oxytocin and ADH. Neurohormones are the hormones that are released by neurons of the posterior pituitary gland.
Thus, the correct answer is option E.

what kind of mutation occurred when the DNA strand changed from AATCGTCCG TO AATAGTCCG?
Answer:
Missense Mutation
Explanation:
AAT CGT CCG to AAT AGT CCG where CGT has become AGT is a point mutation. If a point mutation changes the amino acid, it’s called a missense mutation. In this case CGT (arginine) has become AGT (serine).
Why are G protein only found in Eukaryote cell ?
Answer:
they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes
Explanation:
G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.

which of the following would differ if you compared the same reaction taking place with and without an enzyme
a. the chemical energy of the reactants
b. the chemical change of the product
c. the energy required to the reaction
Answer:
The correct answer is - option C.
Explanation:
Chemical energy is the energy that every substance or chemical have and its not affected by the presence or absence of the enzyme, while the activation energy is the required energy to initiate for a chemical reaction. If the energy of the chemical reaction is less than the activation energy reaction will not take place.
Presence of a enzyme lowers the amount of the energy for the initiating the reaction which is activation energy and the chemical reaction takes place.
Thus, the correct answer is - option C.

In meiosis, each centromere has a spindle fiber attached only to one side. In mitosis, each centromere has a spindle attached to how many sides?
Answer:
In mitosis, each centromere has a spindle attached on both side of centromere
Explanation:
In mitosis, each centromere has a spindle attached on both side of centromere because Spindle fibers move chromosomes during cell division by attaching to chromosome arms and centromeres. A centromere is the specific region of a chromosome where replicates are linked together.
Spindle fibers are active in mitosis and also meiosis and they move throughout the cells and also direct chromosomes to move to where they need to move to.
Spindle fibers function in centromere in mitosis and meiosis by pulling homologous chromosomes apart after they might have been replicated to prepare for division.
A researcher discovers that polar bears have very good insulation and very think hair (similar to pandas). However, they do not show the rest of the panda behaviors. For example, they have high daily energy expenditure and are very active. Why are the panda and polar bear so different
Answer:
Panda and polar bear have some similar characteristics but they also have differences in their behaviors such as polar bears have high daily energy expenditure and are very active while pandas are not.
The panda and polar bear so different because of the geographical difference where they live.
Polar bears are marine mammals and live in north pole perform swimming in north oceans and also move on ice flows, where they catch seals for survival, it makes them active and energetic.
While Pandas are found in China bamboo forests and are herbivores. They eat leaves from bamboo trees, for which they do not require to be more active and get their food easily. So, Pandas are not active as polar bears.
As the climate of North pole and China is cold, both polar bear and panda have very good insulation
