The figures below illustrate the similarities between ATP synthesis in mitochondria and chloroplasts.
The figures can best assist in answering which of the following questions?
In both processes, the electron transport chain generates an electrochemical gradient which "powers" ATP synthase.
The sources that drive the electron transport chains are not visible in the figures. Light energy drives the chloroplast electron transport chain. Glucose is the original source of energy for the mitochondrial electron transport chain.
No indication of temperature is given in the figures.
Although the two processes are likely related evolutionarily, the figures don't really help in providing evidence for the relationship.
