Question

What gets passed through the electron transport chain and both photosystems to create energy?

A. electrons
B. oxygen
C. pigments
D. ATP​

Answer 1

Answer: Electrons

Explanation: The electron transport chain is a series of molecules that accept or donate electrons easily

Answer 2

A. electrons

Step-by-step explanation:

Energy in form of ATP is generated at both cellular respiration and photosynthesis. In cellular respiration, energy (ATP) is synthesized in the mitochondria when ELECTRONS (e-) passes through series of complexes composed of proteins called ELECTRON TRANSPORT CHAIN.

On the other hand, ATP is synthesized when ELECTRONS produced from splitting water i.e photolysis of water, passes through photosystems 1&2 in the chloroplast (thylakoid).
