What do mitochondrial and thylakoid membranes have in common?

a. they both use energy carriers that were made in the krebs cycle.
b. they both are involved in cellular respiration in animal cells.
c. they both contain the chlorophyll pigment.
d. they both use atp synthase proteins in atp production.

Mitochodrial and Thylakoid membranes both use adenosine triphosphate or ATP synthase proteins in ATP production. They are sites of electron transport. Both Mitochodrial and Thylakoid membranes is a place where ATP is produced. Mitochondria is found in all living cells while Thylakoid is found in plants. 

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass
