Final answer:
The movement of water across the plasma membrane is known as osmosis, not the movement of hydrogen ions or glucose, which require specific transport proteins to cross membranes.
Step-by-step explanation:
The movement of water across the plasma membrane can be described by all of the following except the movement of hydrogen ions across a mitochondrial membrane and the movement of glucose through the cell membrane.
The correct term for the movement of water across the plasma membrane is osmosis, which is the diffusion of water through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration, attempting to equalize solute concentrations across the membrane.
Water movement typically occurs via facilitated diffusion through protein channels known as aquaporins or by slipping between the lipid tails of the plasma membrane itself without expenditure of energy.
Other substances like glucose require specific transport proteins to cross the plasma membrane, as they cannot move freely due to their size or polarity.
Similarly, ions such as hydrogen have specific transport mechanisms and typically move across mitochondrial membranes rather than plasma membranes in the process of ATP production.
