Molecular Machines Quiz

Biological molecular machines are used to transport cargo within a cell, power the movement of organisms, synthesize proteins, and separate strands of DNA.

Molecular machines are of nanometer size, protein-based in nature, and depend on ATP or energy stored in electrochemical gradient to generate mechanical force via conformational changes in their structure. Biological molecular machines are either rotary or linear.

DNA-based molecular motors, walkers, tweezers, gears, springs, robots, transporters, and interlocked structures such as DNA rotaxanes and catenanes.

<p>ATP synthase, also called F0F1-ATPase, is a rotary form of motor that catalyzes the synthesis of adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate using the energy stored in a proton gradient.</p> Signup and view all the answers
