This Family of ATPases Is Structurally Related to the Turbine-Like

question 30

Multiple Choice

This family of ATPases is structurally related to the turbine-like pumps that acidify lysosomes and vesicles; however, they usually function in reverse, generating ATP from ADP and Pᵢ using proton gradients across membranes. What are they called?

• A) P-type pumps
• B) ABC transporters
• C) V-type pumps
• D) F-type pumps
• E) Permeases

Definitions:

Parallel Connection

A way of connecting electrical components in a circuit so that each component is directly connected to the voltage source, and the current can flow along multiple pathways.

Total Capacitance

The overall capacity of an electrical circuit to store an electric charge, often measured in farads (F).

μ F

Microfarad, a unit of capacitance equal to one millionth of a farad, used to measure the storage of electrical charge.

Dielectric Stress

The molecular stress placed on a dielectric material proportional to the level of applied voltage.
