what do mitochondrial and thylakoid membranes have in common
A) they both contain the chlorophyll pigment
B) they both are sites of electron transport chains
C) they both produce FAD and NADH molecules
D) they both are involved in cellular respiration in animal cells

Answer 1

Answer:

it is b

Explanation:

go get'em tiger.lol,

Answer 2

The answer is B because mitochondria and thylakoid membrane are both sites of electron transport chains.

• Mitochondria is an organelle present in all eukaryotic cells like plants, animals, fungi etc. It is referred to as the power house of the cell because a process called CELLULAR RESPIRATION, which supplies energy to the cell, occurs there. The last step in the synthesis of energy in the mitochondria is the ELECTRON TRANSPORT CHAIN (ETC).

• Thylakoid membrane is a compartment of an organelle called CHLOROPLAST. Chloroplast is present only in plant cells, which performs photosynthesis. A stage of photosynthesis called LIGHT REACTION occurs in the thylakoid. Electron transport chain (ETC) also takes place in the thylakoid membrane in order to synthesize the energy needed for the photosynthetic process.

Therefore, the occurrence of ELECTRON TRANSPORT CHAIN (ETC) is a common feature of both mitochondria and thylakoid membrane of the chloroplast.
