Stem cells are cells that are undifferentiated, and therefore have the potential to differentiate into a wide variety of specialized cell types. How might stem cells most likely be used in the future to treat human disease? a. Stem cells could be modified to produce chemicals that kill bacteria and viruses.
b. Stem cells could potentially be used as a source of renewable healthy cells and tissues.
c. Stem cells could be used to prevent genetic mutations that occur at birth.
d. Stem cells could be used as vectors to insert genetic information into human DNA.

What drives the atp synthase reactions that produce atp

Omg substrates with the same size and shape as the active site will bind to the enzyme. why is the key labeled the “bad” substrate?
