Why are some bacteria, such as those of the genera mycobacterium and nocardia, not effectively stained with the gram stain?
Answer:
Some bacteria, such as those of the genera mycobacterium and nocardia, not effectively stained with the gram stain because they have too much peptidoglycan in their cell walls.
Explanation:
Across most types of bacteria, the cytoplasmic membranes is encased in a hard material called peptidoglycan. It helps maintain cell shape all across the life cycle and shields bacterial cells against environmental stress. The production of peptidoglycan has a significant role in controlling bacterial cell division. The bacterial cell wall's peptidoglycan plays a structural role by providing structural support and balancing the cytoplasm's osmolarity. Additionally, peptidoglycan participates in binary fission throughout bacterial cell division. Christian Gram, a microbiologist, developed a test in 1884 which might identify whether a bacterium possessed a strong, mesh-like membrane known as peptidoglycan. Numerous bacteriophages, eukaryotic, and bacteria all generate peptididoglycan hydrolases.

How do electrostatic interactions contribute to the free enrgy of hydrolysis of atp?
Answer:
Electrostatic repulsion destabilizes ATP relative to the hydrolysis products and therefore makes hydrolysis favorable.
Explanation:
Whenever in contact with water, the highly unstable molecule of ATP hydrolyzes into ADP as well as inorganic phosphate. Those two high-energy containing phosphate bonds inside this molecule are what give it its high energy. When the high-energy containing phosphoanhydride bonds within the adenosine triphosphate (ATP) are broken, like inside the muscles, energy that had previously been deposited in these bonds is freed through the catabolism method known as ATP hydrolysis. The amount of energy should always be entered into ATP synthesis because ATP hydrolysis radiates. An endergonic mechanism is a phosphorylation, or perhaps the condensing of phosphate groups into AMP. Energy is required for a variety of vital biological and cellular functions, including ATP hydrolysis.

What effect would substituting the atom in the circle with the atoms in the square (a) have on the chemical properties of the resulting molecule?
The correct answer is option f) Both a and c.
We know that the formation of the carbocation intermediate is the rate-limiting step in an SN1 reaction. The rate of this phase, and hence the rate of the total substitution reaction, is determined by the activation energy for the process in which the link between the carbon and the leaving group breaks and a carbocation is formed. According to Hammond's postulate, the faster this first bond-breaking event occurs, the more stable the carbocation intermediate is. In other words, the stability of the resulting carbocation intermediate greatly influences the chance that a nucleophilic substitution process would occur through a dissociative SN1 mechanism.
A carbocation is a positively charged entity that has very few electrons, thus anything that adds electron density to the area of electron poverty will help stabilize it. However, an electron-withdrawing group will destabilize a carbocation.
Alkyl groups, such as methyl, ethyl, and similar compounds, are weak electron-donor groups that stabilize adjacent carbocations. This means that more substituted carbocations are often more stable; for example, a tert-butyl carbocation is more stable than an isopropyl carbocation. Since methyl carbocations are even less stable than primary carbocations, they are rarely seen as reaction intermediates.
Additionally, adding methyl groups as new substituents to a molecule often makes it more lipophilic and less soluble in water. Therefore, it decreases solubility.
Therefore, if the H-atom in the ethane is replaced by the methyl group, then the resultant molecule has the following effects:
