How do you use passive transport in a sentence?
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
What is net movement of substances across plasma membrane without additional energy?
Diffusion. With the need of energy, it would be called active transport.
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
Does active transport get substances across a cell membrane?
Yes, active transport is a process that uses energy to move substances across a cell membrane against their concentration gradient. This enables the cell to accumulate certain molecules or ions inside the cell or remove them from the cell.
Do enzymes change shape to move substances across the plasma membrane?
Enzymes and the substrates they work on fit like a lock and key, if you change the shape of the key, the lock won't open. An enzyme whose shape changes is no longer able to activate the reaction of the substrate.
What is it called when substances move past the membrane without using energy?
Passive transport is when substances move past the membrane without using any energy.
What is it called when substances move past the membrane without using any energy?
Passive transport is when substances move past the membrane without using any energy.
Substances that move across a cell membrane without using energy?
Passive transport is the movement of substances across a cell membrane without the use of energy. This process includes simple diffusion, facilitated diffusion, and osmosis. These mechanisms rely on the concentration gradient to drive the movement of molecules.
What uses a protein to move a molecule across a membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.

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.
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
How does active transport work against the concentration gradient to move substances across a cell membrane?
Active transport is a process in which cells use energy to move substances against their concentration gradient, from an area of low concentration to an area of high concentration, across the cell membrane. This is achieved by using specialized proteins called pumps that actively transport the substances across the membrane, requiring energy in the form of ATP.
When sugars pass across a membrane without the use of energy?
Passive transport.
How does passive transport move substances across a cell membrane in the direction of their concentration gradient?
Passive transport moves substances across a cell membrane in the direction of their concentration gradient without requiring energy input from the cell. This process relies on the natural movement of molecules from areas of high concentration to areas of low concentration, facilitated by protein channels or carriers in the cell membrane.
The use of energy to move substances across a cell membrane describes?
Active transport, which requires energy in the form of ATP to move substances against their concentration gradient across a cell membrane. This process involves specific protein pumps that bind to the molecule being transported, consuming ATP to change conformation and move the molecule across the membrane.
