A doctor is exploring some tissues with a blunt probe. she notices that the tissue is white and fatty and seems to be concentrated within the spinal cord. she is observing A. gray matter B. Myelin Sheaths


The correct answer is option B, that is, myelin sheaths.


Myelin refers to an insulating layer, or a sheath, which get produced surrounding the nerves, comprising those in the spinal cord and the brain. It is formed of fatty substances and protein. This myelin sheath permits electrical impulses to conduct briskly and effectively between the nerve cells.  

The neuron’s myelin sheath comprises the cells containing fat, which shield the axon from electrical activity. The insulation functions to enhance the rate of conduction of signals. The myelin sheath provides the whitish look to the brain's white matter.

Humans have a well defined range of pH tolerance; 7.35-7.45. In the context of molecules and macromolecules, what effects might you see from departure from normal pH?

The pH range of tolerance for humans is well defined and very small for a number of reasons.
First, we must understand that all biological reactions in our body are carried out by biological catalysts called enzymes. These enzymes operate under specific pH and and temperature conditions. Deviation from these conditions will result in inefficiency of the enzymes' functions. This may be observed macroscopic-ally as poor digestion among other things.
Next, an equilibrium is necessary for the movement of CO2 in red blood cells. CO2 is kept in equilibrium in the form of carbonic acid. This equilibrium may be disturbed by the change in pH; resulting in a difficulty to breathe. 
Other effects such as fatigue, headaches and nausea may also be observed as the blood circulates throughout your body and its functions will be impaired by the changed pH.

5) Which of these organic molecules functions to help speed up biological chemical reactions? A)lipids B)proteins C)nucleic acids D)carbohydrates

The right answer is B. proteins.

A catalyst is a chemical species (which may be a protein or a cation ...) that allows the implementation of catalysis. As it is not consumed during the chemical reaction, it is used in small quantities and does not appear in the equation of the balance of the reaction that it can accelerate.

A catalyst has the effect of modifying the very nature of the steps which make it possible to pass reagents to the products. However, it is not able to modify either the direction of the evolution of the system or its state of equilibrium. It only influences the chemical kinetics, accelerating a reaction or allowing one reaction to be preferred over another.

A catalyst is specific for one type of reaction, i.e. the same catalyst cannot be effective for all chemical reactions.

One gene controls the synthesis of one polypeptide.


The concept of one gene-one enzyme was given by Beadle and Tatum. This concept states that a gene codes only for a single enzyme. The enzyme affects the metabolic pathway of the reaction.

The enzymes are the proteins which performs a metabolic function. The protein is made up of amino acids. The amino acids are joined together to form a  linear chain. This linear chain is also called as a polypeptide.

Which of the following statements about the formation of polypeptides from amino acids is true?


The correct answer is - A bond forms between the carboxyl functional group of one amino acid and the amino functional group of the other amino acid.


A polypeptide is a polymer made up of amino acids linked together by peptide bonds. A peptide bond is formed between two amino acids in which the α-amino group of one amino acid is linked to the α-carboxyl group of another amino acid.  So peptide bonds are amide linkage.

This amide linkage is formed by the removal of one water molecule so it is a dehydration reaction. The linked amino acids are called amino acid residues. When many amino acids are joined together by the peptide linkage they are called polypeptides.

Therefore the correct answer is- A bond forms between the carboxyl functional group of one amino acid and the amino functional group of the other amino acid.

How are proteins and nucleic acids related? A.They both provide energy. B.They both carry genetic information. C.The structure of proteins is determined by nucleic acids. D.The subunits of nucleic acids are also the subunits of proteins.

Proteins and nucleic acids are related because the structure of proteins is determined by nucleic acids.

Further Explanation

Nucleic acids

  • Nucleic acids are one of the four major bio-molecules in nature. Nuclei acids is divided into two; RNA and DNA.
  • The building blocks of nucleic acids are Nucleotide bases which are made by a nitrogenous base, a sugar and a phosphate group.


  • DNA is a nuclei acid that is responsible for carrying genetic information in living organisms.
  • It is through DNA that genetic information is passed from one organism to another through the process of DNA replication.
  • Additionally, it carries the information that is used to make proteins which performs various functions in living cells.
  • Each Nucleotide in DNA contains a nitrogenous base, a deoxyribose sugar, and a phosphate group.
  • DNA molecules are made up of nitrogenous bases; Adenine, Guanine, Cytosine and Thymine.


  • Ribonucleic acid (RNA) is a type of nucleic acid, a molecule that plays a major role in the flow of information from the DNA to the proteins. For a gene to be expressed information has to be passed through the RNA.
  • Each nucleotide in RNA contains a nitrogenous base, a ribose sugar, and a phosphate group.
  • Nitrogenous bases in RNA includes; Adenine, Guanine, Cytosine and uracil. Thymine in DNA is replaced with Uracil.


  • Proteins are one of the major biomolecules that exists in nature.
  • They are made of amino acids which are the building blocks.

Protein synthesis

  • Proteins synthesis occurs in ribosomes through a process known as translation.
  • During translation the genetic code carried by the messenger RNA from the DNA through transcription is interpreted to code for specific amino acids. The amino acids are then joined to form proteins with the help of transfer RNA.
