The "powerhouse" of a prokaryotic cell can be the cell membrane. That's where they produce their ATP.
cell membrane
Most of the cell's ATP is made in the inner membrane of the mitochondria through a process called oxidative phosphorylation. ATP is then stored and used as an energy source by the cell for various cellular activities.
Mitochondria are double-membrane organelles that specialize in ATP production through cellular respiration. They have an outer membrane and an inner membrane that houses the electron transport chain where ATP is generated. Mitochondria are often referred to as the powerhouse of the cell due to their role in producing energy for the cell.
Membrane proteins are important to carry out the process of selective transport across cells. Na/K channel proteins, ABC transsporters, ATP synthase, ETC chain proteins are some good examples. They mostly cost energy to transport a molecule (active transport) and other protein actually synthesize ATP (ATP synthase)
Facilitated diffusion is an inactive mode.So no ATP cost.

No, passive transport does not require ATP for the movement of molecules across the cell membrane.

What does a cell membrane do in a plant cell?A cell membrane creates a barrier that is semipermeable. The barrier separates the plant's internal structure consisting of organelles from the external environment. Exchange of molecules between the two environments exists in the form of passive transport (requires no ATP) and active transport (requires the expenditure of ATP).
Membrane activities that require energy from ATP hydrolysis include active transport, endocytosis, exocytosis, and membrane protein pumps. During these processes, ATP is hydrolyzed to provide energy for the movement of molecules across the membrane against their concentration gradient.
Yes, the process of endocytosis does require ATP for its functioning. ATP provides the energy needed for the cell to engulf and internalize substances through the cell membrane.
transport across the membrane
Mitochondria are double-membrane organelles that specialize in ATP production through cellular respiration. They have an outer membrane and an inner membrane that houses the electron transport chain where ATP is generated. Mitochondria are often referred to as the powerhouse of the cell due to their role in producing energy for the cell.
