(a) Pepsin is a protein-digesting enzyme found in the stomach. It
has an optimum pH of 2 and is fully denatured at pH 6. Sketch a
curve on the graph to show the effect of pH on the rate of
reaction of pepsin.
Please find attached a sketch of the rate of reaction enhanced by pepsin at various pH, which shows a peak in the reaction rate at a pH of 2, and a reduction to (almost) zero rate of reaction at a pH of 6.
How can the variation of the rate of reaction with pH be graphically presented?(a) The given parameters for the enzyme, pepsin are;
Type of enzyme = Protein–digesting enzymeLocation of enzyme = The stomachEnzyme optimum pH = 2pH at which the enzyme is denatured = 6Required;
A sketch of a curve that shows the effect of varying pH values on the reaction rate of pepsin.
Solution;
An enzyme is denatured when it is not able to function to affect the rate of a reaction due to the loss of its tertiary or three dimensional structure.
The rate of the reaction when pepsin is denatured at a pH of 6 can therefore be taken as zero.
The graph of the variation of the rate of reaction for pepsin with pH consists of a curve that has a peak reaction rate at a pH of 2, and slopes downwards towards a reaction rate of zero at a pH of 6.

A virus is isolated, and individual virions appear spherical. what type of virus is this?
For each of the following scenarios, describe the most likely pathway from beginning of synthesis (when peptide bonds are made) to final location for
a protein. Include short descriptions of key steps. The scenarios are: a protein that floats freely in the cytoplasm; a protein that is in the lumen (liquid
interior) of a lysosome; a protein that is secreted from a cell; and a protein that is imbedded in the plasma membrane of a cell.
Both the nucleus and the cytoplasm of a cell are the sites where protein synthesis takes place. A DNA template is used to create RNA in the nucleus. The translation is then carried out by this RNA in the cytoplasm.
Transcription and translation are the two processes that make up protein synthesis. A segment of DNA called a gene, which codes for a protein, is transformed into a template molecule called messenger RNA during transcription (mRNA). In the cell's nucleus, enzymes referred to as RNA polymerases perform this conversion. [2] Eukaryotes make this mRNA prematurely at first (pre-mRNA), which then goes through post-transcriptional changes to produce mature mRNA.
Nuclear pores allow the mature mRNA to be evacuated from the cell nucleus and transported to the cytoplasm, where translation can take place. Ribosomes read the mRNA during translation, using its nucleotide sequence to infer the order of the amino acids. To create a polypeptide chain from the encoded amino acids, the ribosomes catalyse the production of covalent peptide bonds. After translation, the polypeptide chain needs to fold in order to create a functioning protein. For instance, for an enzyme to work properly, the polypeptide chain needs to fold properly in order to create a functional active site. The polypeptide chain initially forms a series of smaller underlying structures termed secondary structures before it can assume a useful three-dimensional (3D) shape.

One species gain from parasitic interactions while the other loses. Medical microbiology studies a large majority of parasitic, human tissue-eating bacteria. For instance, parasitic bacteria are responsible for cholera, leishmaniasis, and giardia.
Any coexistence of two or more biological species is referred to as symbiosis. These connections are typically long-lasting and have a significant effect on the fitness of either one or both animals. The advantages and physical characteristics of symbiotic interactions are classified. In nature, relationships in which both species profit are known as mutualistic relationships. Numerous instances of mutualistic bacteria in the stomach that support digestion in both humans and animals may be found in the field of microbiology. A relationship between species known as commensalism occurs when one species benefit and the other is unaffected.

What was the calculated concentration of protein of Serum Specimen A? To receive credit,
report the value as a whole number and the units of measure!
By making use of a standard curve made up of known quantities of a pure sample protein, protein concentration is calculated. The type of chemical used can be used to separate these protein test techniques into two groups.
Either assessing the UV absorbance at 280 [tex]nm[/tex] or quantitatively reacting the protein with dyes and/or metal ions can be used to figure out the protein concentration of sample preparation (Bradford, Lowry, or BCA assays). Simply multiply the dilution factor by the undiluted, unknown sample's protein concentration to determine its concentration. 0.5 x 10 equals 5 [tex]\frac{mg}{ml}[/tex]. By contrasting the colour produced by the "unknown" solution with the colour generated by solution of known proteins, or the standard curve, one can determine the protein content of an unknown.

Which set of twins (3-year-old or 50-year-old) have the most similar DNA methylation profiles? Provide a brief explanation of your observations.
A DNA base is altered biochemically during DNA methylation, which typically takes place during gametogenesis and after fertilization.
The DNA methyltransferases DNMT1, DNMT3A, and DNMT3B keep methylation marks in tact after each cell division. Although the majority of methylation marks are stable, there is typically 10% to 20% variation over time. Ly cytosine undergoes enzymatic 5-carbon methylation. DNA methylation represents the best characterized form of epigenetic modification. DNA methylation is written onto the genome by two methyltransferases, known as Dnmt3a and Dnmt3b.These enzymes catalyze the addition . Aging is often marked by the establishment of global hypomethylation and regions of CpG island hypermethylation. These changes in the epigenetic landscape may contribute to aging by adversely affecting genomic stability and gene regulation.

Mr. Shepherd has gone outside to shovel snow on a cold day. How does his body maintain a relatively constant body temperature? What is this process called?
The thermoregulatory center, which is primarily responsible for controlling body temperature, is situated in the preoptic area of the hypothalamus.
Homeostasis is the term used to describe the process of maintaining a constant internal environment within an organism.
Vasodilation and vasoconstriction, which result in an increase or reduction in blood flow to the skin, are the primary thermoregulatory mechanisms.
On the skin's surface (peripheral receptors), in the pre-optic region of the anterior hypothalamus (central receptors), and in other areas of the body exist thermal sensing cells or thermal sensors for heat and cold.Blood flow to the skin increases in hot weather (making it red), while it reduces in cold weather (the skin becomes paler).The body employs perspiration in addition to blood flow to control body temperature because sweating causes water on the skin's surface to evaporate and heat to escape, which lowers body temperature.We can therefore draw the conclusion that the internal environment, a significant indicator, and the maintenance of body temperature are strongly associated (homeostasis).
