When a molecule uses energy to move a cross a semipermeable membrane what is it called?
When a molecule uses energy to move across a semipermeable membrane, it is called active transport. This process requires ATP or another energy source to transport substances against their concentration gradient, allowing cells to maintain specific concentrations of ions and molecules. Active transport is essential for various cellular functions, including nutrient uptake and waste removal.

A special molecule that uses energy to push molecules through a membrane of a cell is called?
The special molecule is called ATP, which stands for adenosine triphosphate. ATP provides the necessary energy to power transport proteins in the cell membrane to move molecules across it.

Movement of substances from higher to lower concentration across a semipermeable membrane that must have a specific protein carrier but no energy expenditure is called?
Facilitated diffusion is the movement of substances from higher to lower concentration across a semipermeable membrane with the help of specific protein carriers, without requiring energy input.
The rate of diffusion through a semipermeable membrane will be lowest when?
The rate of diffusion through a semipermeable membrane will be lowest when temperatures are low. Lower temperatures decrease the energy of the molecules, which in turn decreases the rate of diffusion.
Minimum gibbs free energy is NOT attained by a semipermeable membrane. True or false?
True. The minimum Gibbs free energy is not attained by a semipermeable membrane, as the membrane itself does not participate in any chemical reactions that could lower the system's overall free energy. The minimum free energy is achieved through chemical reactions occurring within the system.
The diffusion of water across a semipermeable membrane is called?
When water diffuses through a semipermeable membrane, such as a cell, it is called osmosis. In osmosis the concentration of water will differ on one side of the membrane from that of the other side. Water molecules will tend to diffuse from the high concentration side to the lower.
