True or false: Since ATP is generated in chloroplasts, cells capable of undergoing photosynthesis do not require mitochondria.
The proton-motive force is a measure of the potential energy generated across the mitochondrial inner membrane during electron transport. Explain the factors that constitute this potential energy, that will be converted to the chemical energy of ATP by the cell
The inner mitochondrial membrane exhibits all of the fundamental characteristics of a typical cell membrane, but it also has several unique characteristics that are closely associated with its role in oxidative phosphorylation. What are these unique characteristics? How does each contribute to the function of the inner membrane?
