What ways of moving molecules across a membrane requires energy?
Active Transport.
What process drives molecules across a membrane against a concentration gradient?
Active Transport.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
What assists the movement of polar molecules across the membrane A. Passive Transport B. Active Transport?
Polar molecules must pass through the membrane via active transport. This is because the cellular membrane is mostly nonpolar, and polar and nonpolar molecules repel each other. Only nonpolar molecule (i.e. hormones) can pass through the membrane without active transportation.
What is the act of molecules crossing a membrane?
passive or active transport
What ways of moving molecules across a membrane requires energy?
Active Transport.
What ways molecules cross the membrane with energy?
active transport
What process drives molecules across a membrane against a concentration gradient?
Active Transport.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
Which is a form of active transport?
active transport as it requires energy provided by ATP

proteins

When the cell itself plays an active role in the passing of molecules through its membrane?
active transport
Describe a form of active transport similar to the work of carrier proteins?
Molecules are moved through the cell membrane by active transport.
Active transport is the process of what?
Active transport is the process of molecules being moved across a membrane using energy. Passive transport moves the molecules without using energy.
What is the movement of molecules through a cell membrane requiring energy?
active transport
