A suspension of yeast cells is being grown under anaerobic conditions such that glucose is degraded to ethanol and carbon dioxide. To follow this process by monitoring the release of CO214, at which positions in the glucose molecule would the C14 label need to be incorporated
Answer:
carbons 3 and 4
Explanation:
Alcoholic fermentation is an anaerobic (non-oxygen-requiring) pathway capable of converting one mole of glucose (C6H12O6) into two moles of ethanol (C2H5OH) and two moles of carbon dioxide (CO2), producing during this process two moles of ATP. The overall chemical reaction is as follow: C6H12O6 (glucose) >> 2 C2H5OH (ethanol) + 2 CO2. During this process (fermentation), energy is obtained from the glycolysis process by which each glucose molecule is broken down into two pyruvate molecules (2 CH3COCOO−). Pyruvic acid is an organic acid that ionizes to produce a hydrogen ion and a molecule of pyruvate. Subsequently, this pyruvate is then converted into ethanol and CO2, generating NAD+, i.e., the oxidized form of nicotinamide adenine dinucleotide or NAD, which is required for glycolysis (and therefore to produce ATP). Moreover, dismutation refers to the redox reaction by which one compound with an intermediate oxidation state converts into two compounds. In consequence, the CO2 generated during fermentation arises from the dismutation of pyruvic acid. During this process, the major source of CO2 is carbon 3 (C3) and carbon 4 (C4) of the glucose as a result of the dismutation of pyruvate, and thereby these positions in the glucose molecule would the C14 label need to be incorporated.

The kinetics analyses of an enzyme are measured as a function of substrate concentration in the presence and in the absence of 2mM inhibitor
[S] (microM): 3, 5, 10, 30, 90
Velocity (micromol/min) No Inhibitor: 10.4, 14.5, 22.5, 33.8, 40.5
Velocity (micromol/min) With Inhibitor: 4.1, 6.4, 11.3, 22.6, 33.8
Required:
What are the values of Vmax and Km in the absence of inhibitor? In its presence?
Answer:
take the reciprocal of the values as 1/S and 1/V and plot the values on lineweaver-burk plot.
so the re-arranged data is as following
1/S 1/V (no inhibitor) 1/V (with inhibitor)
0.333 0.096 0.244
0.2 0.068 0.156
0.1 0.044 0.088
0.033 0.029 0.044
0.011 0.024 0.029
and the plotted lineweaver-burk plot with the equation of straight line would be....
where, first line represents the velocity of reaction with no inhibitor and second line represent the velocity in presence of inhibitor. X-axis has the substrate concentration as 1/S and y-axis has the velocity as 1/V.
as per the plot, equation of line on the lineweaver-burk plot, Y = mx + c, where c = 1/Vmax and m = Km/Vmax.
so solve for the given equations.
First, equation of line in the absence of inhibitor is Y = 0.23x + 0.021
so Vmax = 1/0.021 = 47.6 micromol/min
and Km/Vmax = 0.23, or Km = 0.23 x 47.6
Km = 10.95
Km do not have a unit, so 10.95 x 10-6 or as per your values round it up to 1 decimal point as 1.1 x 10-5
so value of Vmax = 47.6micromol/min and Km = 1.1 x 10-5 in the absence of inhibitor.
similarly, equation of line in the presence of inhibitor is given as Y = 0.67x + 0.021
so Vmax = 1/0.021 = 47.6 micromol/min
and Km/Vmax = 0.67
or Km = 0.67 x Vmax = 0.67 x 47.6 = 31.89
Km do not have a unit, so 31.89 x 10-6 or 3.1 x 10-5
so value of Vmax = 47.6micromol/min and Km = 3.1 x 10-5 in the absence of inhibitor.

What is the role of DNA polymerase enzymes in replication?
(A) unzipping the double helix by breaking down the hydrogen bonds
(B) adding the free nucleotides to the complementary strand of DNA
(C) splitting the DNA molecule
(D)connecting the fragments on the lagging strand of DNA
Answer:
A
Explanation:
the function of DNA polymerase is to unzip the double helix structure of DNA by breaking down the weak hydrogen bond
Answer:
(B) adding the free nucleotides to the complementary strand of DNA
Explanation:
A DNA polymerase is an enzyme capable of creating new DNA molecules by sequentially adding nucleotides to the three prime (3')-end of a DNA strand. A DNA strand is a polynucleotide chain composed of a linear series of nucleotides, each consisting of a deoxyribose sugar, and phosphate, and a base (i.e., thymine, guanine, cytosine and adenine). Before a cell starts to divide, it needs first to replicate its genetic material by using DNA polymerases that duplicate the cell's DNA during the interphase (S phase). During this process (DNA replication), an enzyme known as helicase unwinds the DNA molecule, which is made up of two antiparallel strands oriented in opposite 3′-5′ directions to each other. Subsequently, each strand is used as a template for its replication through DNA polymerases that can add nucleotides (one at time) to an existing short fragment of RNA, i.e., the primer sequence, which is paired with the template DNA strand.
Products of DNA replication
DNA replication occurs during Interphase. What Image shows the products of replication. If the parent strands are blue and the new strands are red? Click the correct box.
Answer:
The red one.
Explanation:
The red colour strands are the products of replication in which new DNA molecules are formed. The main purpose of replication is to produce extra set of DNA molecules for the new cell so that each cell receives extra molecules of DNA. Due to DNA replication, the cell has two types of DNA i.e. parent strands and new strands. The parent strands are blue in colour whereas the new strands are red in colour.

Respuesta corta: Produciendo un sentimiento de satisfacción.
Explanation
En el texto se hace referencia a una investigación para analizar la relación entre las redes sociales y el cerebro de los adolescentes. Para ello los investigadores utilizaron imágenes magnéticas del cerebros de los 32 adolescentes estudiados. Una vez terminaron el estudio se dan cuenta que "una estructura del cerebro, llamada núcleo accumbens, se activa más cuantos más likes tuviera una imagen". Además, el autor del texto agrega que "Esto es interesante si se tiene en cuenta que este órgano nervioso es el responsable de que experimentemos momentos de placer intensos al ganar un premio, comer helado, etc". De acuerdo a lo anterior se puede interpretar que las redes sociales influyen en el cerebro de los adolescentes debido a que produce en ellos un sentimiento de satisfacción o reconocimiento a recibir "likes" de otras personas. Además, este sentimiento se puede interpretar como aprobación por parte de las demás personas.

Meiotic recombination produces new genetic information in sister chromatids.This Happens During prophase I. Order the stages of prophase I chronologically: ____ Diplotene.-The synaptonemal complex dissociates; homologous pairs remain attached (chiasmata).
Answer:
See the answer below
Explanation:
The various stages of propase I of meiosis I in chronological order would be
1. Leptotene
2. Zygotene
3. Pachytene
4. Diplotene
5. Diakinesis
The leptotene stage is characterized by the thickening or condensation of the genetic material in the nucleus such that 'thick thread' structures is formed.
At the zygotene stage, the thickness advances and structures can be seen as chromosomes under the microscope. Homologous chromosomes are seen pairing up (synapsis) through the formation of synaptonemal complex to form tetrads or bivalents.
At pachytene, an exchange of chromosomal segments between synapsed homologous chromosomes occur in a process known as crossing over. The exchange point along the synapsed chromosomes are known as the chiasmata. After the crossing over, homologous chromosomes begin to separate but remains joined at the chiasmata.
At diplotene, the dissolution of the synaptonemal complex occur and homologous chromosomes still held together by the chiasmata begin to repel one another. The chiasmata becomes terminalized.
At Diakinesis, chromosomal condensation is completed and the cell is conditioned to progress to metaphase I of meiosis I.

Osteology 1) For the following fill-in the correct anatomical term: (ex. Inferior, superior, posterior, etc.) a. Your knee is ____________ relative to your navel. b. Your sternum is _____________ relative to your right side.
Answer:
a. inferior
b. medial
Explanation:
There are three planes that are used to divide the human body: 1-transverse plane, which is a horizontal line that divides the body into a superior (above) section and an inferior (below) section; 2-median sagittal plane, which is a vertical line that divides the body into equal left and right portions; and, 3-coronal plane, which divides the body into a ventral (anterior) section and a dorsal (posterior) section. As its name indicates, inferior is the opposite term of 'superior' and refers to a structure that is 'below' something else (for example, the feet are inferior to the head). Moreover, a medial structure refers to a structure that is closer to the midline of the body, and therefore divides the body into equal right and left sections (for example, the nose is medial to the eyes).
