You have discovered an enzyme that can catalyze two different chemical reactions. Which of the following is most likely to be co

rrect?
A) The enzyme contains α-helices and β-pleated sheets.
B) The enzyme is subject to competitive inhibition and allosteric regulation.
C) Two types of allosteric regulation occur: The binding of one molecule activates the enzyme, while the binding of a different molecule inhibits it.
D) Either the enzyme has two distinct active sites or the reactants involved in the two reactions are very similar in size and shape.

The correct option is D.

Enzymes are biological catalysts that speed up the rate of biochemical reactions in living systems by lowering the activation energy required for the reactions to occur. Enzymes take part in various reactions but they are never used up during the course of the reaction.  

Enzymes are very specific in action and will only catalyze certain reactions under optimal conditions. For a single examine to catalyze two different reactions, it implies that the enzyme either have two active sites or the molecules involve in the reaction are very similar in term of size and shape.

Equilibrium is attained when ______
Vikentia [17]

Answer:

When the rates of the forward and reverse reactions have become equal to one another, the reaction has achieved a state of balance. Chemical equilibrium is the state of a system in which the rate of the forward reaction is equal to the rate of the reverse reaction.

What are the contributions of each of these scientists to the cell theory? And how did that information contradict what was beli
SpyIntel [72]

M. J. Schleiden:

In the year 1838, a German botanist presented the first cell theory (Although his theory was ultimately disproved, it did contribute to a change in scientific focus to cellular processes.)

<h3>What is cell?</h3>

All living creatures and body tissues are made up of the smallest unit that can live on its own. The cell membrane, nucleus, and cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates the molecules that enter and exit it.

His theory: Cells make up all plant tissues, and an embryonic plant is made up of just one cell. He declared that the cell is the fundamental building block of all plant matter.

Louis Pasteur- 1855 - German physiologist, physician, pathologist; and anthropologist. Added a third to the cell theory: Omnis Cellula e cellula (all cells develop only from existing cells).- Implied that there was no Spontaneous generation.

Rudolf Virchow- In 1862 he conducted a famous experiment supporting the theory that cells can only come from other cells.

His experiment:

Steralized flasks with straight and curved necks were used to heat nutrient broths. Bacteria only developed in the straight necks because bacteria cells from the air settled in the S-shaped necks' curves. Spontaneous gen did not produce proven cells in the broth.

What alternate form of genes do nucleic acids have that allows them to offer variability allele codon nucleotide chromosome
Y_Kistochka [10]

Answer:

The options to this question are:

A) allele

B) codon

C) nucleotide

D) chromosome

The answer is A) allele

Explanation:

RNA and DNA are the two nucleic acids in living organisms used for transferring and storing genetic information. Deoxyribonucleic acid (DNA) is the genetic material in living organisms that contains segment coding for useful products/proteins and transmits genetic information from one generation to another. These segments are called GENES.

However, genes contain an alternate form responsible for genetic variation in the traits coded for by them. These alternate or variant form of a gene is called ALLELE. In a diploid organism like human, each trait is encoded by genes which contain contrasting pair of alleles that allows variation for that particular trait i.e. two alleles for each gene. For example, height trait in humans are encoded by gene, which possess two alleles; one coding for short variety (t) and the other for tall variety (T).
