What ways of moving molecules across a membrane requires energy?
Active Transport.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What process drives molecules across a membrane against a concentration gradient?
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.
Does diffusion help phloem to absorb minerals from the soil or active transport?
anything
What is moved by active transport?
Molecules are moved by active transport.
Why is active transport of molecules necessary?
To move substances from low to high concentration.
What is the Method of movement that requires the expenditure of ATP molecules is?
active transport
Does active transport result in an even distribution of molecules?
No. Active transport uses energy to transport specific molecules against a concentration gradient. Passive transport will result in an even distribution of molecules because they allow molecules to move down a concentration gradient.
What ways of moving molecules across a membrane requires energy?
Active Transport.
Which is a form of active transport?
active transport as it requires energy provided by ATP
What is it called when molecules uses energy to move across a semipermeable membrane?
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 process drives molecules across a membrane against a concentration gradient?
Active Transport.
How is active transport diffrent from osmosis?
Active transport occurs when molecules are moved from an area of low concentration to an area of high concentration. The cell membrane acts as a semi-permeable barrier during the process. Energy is required for active transport. Osmosis is a type of passive transport. Passive transport is similar to active transport except it requires no energy and molecules move from an area of high concentration to an area of low concentration. Osmosis occurs only if the molecules moving across the cell membrane are WATER molecules.
What is the function of active transport in moving small molecules and ions across the membranes?
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
What ways molecules cross the membrane with energy?
active transport
