ATP (adenosine triphosphate) is the molecule that typically provides the energy needed to push molecules through the membrane of a cell by facilitating active transport processes. This energy is released when ATP is hydrolyzed to ADP (adenosine diphosphate) and inorganic phosphate, powering cellular activities such as transporting molecules across the cell membrane.

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.
What molecule is produced as a result of the hydrogen leaking back through the membrane?
Many molecules can be synthesized using that energy. Most important one is ATP
How do cells transport molecules across a cell membrane?
Molecules can move through the membrane in many ways. If the molecule is hydrophobic (or lipophilic) it can easily pass through the membrane. Other than that, most molecules move through the membrane through channels (which flow towards the molecules concentration gradient) or pumps (which flow against a molecules concentration gradient using energy).
Which requires the use of energy to move a molecule across a cell membrane?
Active transport requires the use of energy to move a molecule across a cell membrane, usually against its concentration gradient. This process relies on protein pumps that use ATP as an energy source to drive the movement of molecules.
Which type of molecule will require some amount of energy to cross the cell membrane?
Polar molecules, ions, and large molecules like proteins typically require energy to cross the cell membrane because they cannot diffuse through the hydrophobic lipid bilayer. This process often involves the use of transport proteins or energy-dependent mechanisms such as active transport.

What uses a protein to move a molecule across a cell membrane without using energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What is the movement of molecules through a cell membrane requiring energy?
active transport
Which requires the use of energy to move a molecule across a cell membrane?
Active transport requires the use of energy to move a molecule across a cell membrane, usually against its concentration gradient. This process relies on protein pumps that use ATP as an energy source to drive the movement of molecules.
How does the size of molecules affect diffusion?
The smaller the molecule, the faster it can diffuse through a medium. Larger molecules have more difficulty moving through the medium due to their size and shape, which slows down the rate of diffusion.
What ways molecules cross the membrane with energy?
Molecules can cross the membrane with energy through active transport, which uses energy (often from ATP) to move molecules against their concentration gradient. Another way is through facilitated diffusion, where molecules move with the help of specific protein channels or carriers that provide energy for their transport.
What is the movement of heat energy from one molecule to the next?
The movement of heat energy from one molecule to the next is called conduction. It occurs through direct contact between molecules, with vibrating molecules passing on their kinetic energy to neighboring molecules.
Which type of molecule will require some amount of energy to cross the cell membrane?
Polar molecules, ions, and large molecules like proteins typically require energy to cross the cell membrane because they cannot diffuse through the hydrophobic lipid bilayer. This process often involves the use of transport proteins or energy-dependent mechanisms such as active transport.
What is the transfer of energy when molecules bump into each other through contact?
When molecules bump into each other through contact, the transfer of energy is known as heat transfer. During the collision, energy is transferred from the molecule with higher energy to the molecule with lower energy, causing an increase in the temperature of the lower energy molecule.
