Halophilic bacteria possess a pigment related to the plant's chlorophyll.

<h3>Halophilic bacteria</h3>

They are bacteria that live in high salt environments. They have a certain feature that enables them to pump out salts in order to maintain normal osmotic conditions in their bodies.

Halophilic bacteria are equipped with bacteriorhodopsin and halorhodopsin. These enable them to photosynthesize like plants. and generate the much-needed ATP for pumping out salts.

Which of the following statements about ATP-powered pumps is NOT true? All ATP-powered pumps contain at least one transmembrane
MAVERICK [17]

Answer:

Only P-, F-, and V-class pumps transport ions.

Explanation:

The distinct classes of ATPases include:

1) Only the P-type ATPase actively transports ions across biological membranes. P-ATPases (also named E1-E2 ATPases) are found both in plasma and organelle membranes. These ATPases serve to transport ions and phospholipids by hydrolyzing ATP to ADP and phosphate.

2) A- and F-ATPases synthesize ATP by transforming the energy from a gradient of ions across the cell membrane.

3) V-ATPase (also known as Vacuolar-H+ ATPases) acidifies vacuole, lysosome, endosome and Golgi membranes. This type of ATPase couples the hydrolysis of ATP to the active transport of protons across biological membranes.

4) E-ATPases hydrolyze extracellular ATP.
