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
Which process requires energy to bring molecules across the cell membrane?
active transport
What helps molecules diffuse across membrane through transport proteins?
A process known as passive transport helps molecules to diffuse across a membrane. Passive transport does not involve the use of chemical energy, unlike active transport does.

Active transport

active transport
What is the movement of molecules across a membrane against their concentration at the expense of ATP energy called?
This process is called active transport.
What helps molecules diffuse across membrane through transport proteins?
A process known as passive transport helps molecules to diffuse across a membrane. Passive transport does not involve the use of chemical energy, unlike active transport does.
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.
Some materials can move across the cell membrane against a concentration gradient by?
Large molecules such as glucose that cannot cross the phospholipid bilayer can still move across the membrane through transport proteins by active transport. Active transport uses energy to move molecules the bilayer.
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.
When engery is required from a cell to move molecules across the cell membrane it is called?
It is called active transport.
What is the function of active transport moving small molecules and ions across cell membrane?
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
When would active transport be used by a cell?
Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.
