What is a function of a bacterium's capsule?
nevsk [136]

The purpose of a bacterium's capsule is protection.

<h3>What use does the capsule of a bacteria serve?</h3>

White blood cells may eat and kill pathogens, but capsules could stop that from happening (phagocytosis). Although the precise mechanism for avoiding phagocytosis is unknown, it may occur because the presence of capsules makes the surface elements of bacteria more slippery, preventing the bacterium from being absorbed by phagocytic cells.

Capsules comprised of bacterial defenses and the host. The main function of the capsules of pathogenic bacteria is to prevent opsonophagocytosis or in the case of Gram-negative bacteria, complement-mediated lysis by shielding the bacterial surface from interactions with the host immune system.

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.
