In general, why might cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-posi

tive bacteria?
Group of answer choices

The mutation rate of gram-negative bacteria is much greater than that of gram-positive bacteria.

The outer membrane of the gram-negative bacteria inhibits penetration of the drug.

The peptidoglycan found in gram-positive bacteria is structurally different from that in gram-negative bacteria.

The gram-negative bacteria do not synthesize peptidoglycan.

The gram-negative bacteria digest these drugs at a much higher rate than gram-positive bacteria.

Mutation rate of Gram negative bacteria is much greater than that of Gram positive bacteria.

Explanation:

The gram positive types of bacteria responsible for causing diseases in humans. It is called as Gram positive bacteria. Both the bacteria are different in structural and physical properties. It is defined as the group of bacteria’s which positive result in gram stain test.

Gram negative bacteria are the group of bacteria’s which gives negative result to the gram stain test. This classification is done according to the cell wall. The cause of common disease by Gram positive bacteria is our anthrax, diphtheria, etc.

Which of the following sequences is correct for the downhill movement of electrons during cellular respiration? A. glucose – cit
Volgvan

Answer:

B. glucose – NADH – electron transport – O2

Explanation:

This is the sequence  from glycolysis in which  glucose molecules are split down to pyruvate, to oxidative phosphorylation.

During this process the electrons are released from glucose  molecule as it is oxidised multiple times as pyruvate, and other molecules formed subsequently in Kreb's cycle, until the oxidative phosphorylation is reached .

The makes the  carrier molecules to be reduced.Thus NAD→NADH,FAD→FADH .

The electrons from above are  transferred in hydrogen atoms  to matrix by these co-enzymes.Where the H is split to electrons  and protons.

The electrons for the ETC, produce the PMF for transporting  protons into the intramembrane space.

The concentration of protons generated the electrochemical gradients  which is needed to produce energy for for phosphorylation of ADP with Pi to form ATP by ATpase synthase.

The electrons moves as chain,and this is finally accepted by oxygen as the final electron acceptor.

Which period is the stage of disease during which the patient begins to present general signs and symptoms?
ELEN [110]

Answer: Option D

Explanation:

Once the pathogen enters the body, it starts dividing and after a certain period of time the patients experience some sign and symptoms of illness.

The prodromal period occurs just after the incubation period. In this phase the pathogen keeps on dividing and the host begins to experience general symptoms and signs of illness.

This is a result of the activation of immune system of the body which results in the swelling, pain, soreness.
