Which of tne followingl is electron carrier?

Explanation

Plastoquinones are molecules that serve as electron carriers in the process of photosynthesis. They help transport electrons during the light-dependent reactions in plants. On the other hand, cytochromes are proteins that also act as electron carriers, specifically in cellular respiration. They play a role in transferring electrons within the electron transport chain to produce ATP. Both are essential for energy production in different biological processes.
