Flagella may best be described as:

Biology
2 answers:
vlada-n [284]3 years ago
6 0

Answer:

The correct answer is number one: <em>Filamentous rotating structures that provide motility may be singular, paired or scattered.</em>

Explanation:

Flagella are organelles defined by function rather than structure.

The primary function is that of locomotion but also being sensitive to chemicals and temperatures outside the cell.

Helicobacter pylori is a good example of flagella: It uses multiple flagella to propel itself through the mucus lining to reach the stomach epithelium.

Sperm cell is a good example, which uses its flagellum to propel itself through the reproductive tract of females.

I hope it helps!

Answer:

1. filamentous rotating structures which porvide motility, may be singular, paired or scattered.

Explanation:

"Bacterial flagella are helically shaped structures containing the protein flagellin. The base of the flagellum (the hook) near the cell surface is attached to the basal body enclosed in the cell envelope. The flagellum rotates in a clockwise or counterclockwise direction, in a motion similar to that of a propeller."

Pseudomonas aeruginosa is a non-fermenting GNR, it grows on EMB. Which of the following would be true (Circle none, one or many)
Dafna11 [192]

Answer:

The correct answer is a. Pseudomonas aeruginosa would be colorless on EMB

Explanation:

Pseudomonas aeruginosa is a gram-positive bacteria that is rod shape. It shows a few nutritional requirements and can even adapt to those conditions in which the other bacteria can be adapt.

It is non-fermentative bacteria so it does not ferment lactose and other carbohydrates. As EMB agar contains lactose and some dye, therefore, the lactose fermenting bacteria ferment the lactose and show good growth and color change.

But as Pseudomonas aeruginosa is a non-fermentative bacteria it does not ferment lactose and does not show any color and forms a colorless colony. Therefore the correct answer is a.

Consider the atps that can be generated via substrate-level phosphorylation. Will glycolysis be useful for generating any atps d
iris [78.8K]

Indeed, glycolysis would be useful for creating ATP as it produces a net increase of ATPs. One glucose particle produces two ATP in a cycle. On the off chance that the ETPUM experiences the procedure of aging, at that point the natural atoms would then be able to be used as the essential electron transporter. Two ATPs would be delivered by means of TCA cycle and yes it will be sufficient to help development.  

Further Explanation:  

Phosphorylation:  

Phosphorylation is the synthetic expansion of a phosphoryl gathering (PO3-) to a natural atom. The expulsion of a phosphoryl gathering is called dephosphorylation. Both phosphorylation and dephosphorylation are done by catalysts (e.g., kinases, phosphotransferases).  

ATP:  

Adenosine triphosphate is an unpredictable natural synthetic that gives vitality to drive numerous procedures in living cells, for example muscle withdrawal, nerve motivation proliferation, and substance amalgamation. Found in all types of life, ATP is regularly alluded to as the "atomic unit of money" of intracellular vitality move.  

ATP utilized for:  

ATP Molecule. The Adenosine triphosphate (ATP) particle is the nucleotide referred to in organic chemistry as the "atomic cash" of intracellular vitality move; that is,ATP can store and move substance vitality inside cells.  

TCA:  

Tricyclic antidepressants (TCAs) are a class of drugs that are utilized basically as antidepressants. TCAs were found in the mid 1950s and were promoted later in the decade. They are named after their concoction structure, which contains three rings of particles.
