Membrane activities that require energy from ATP hydrolysis include active transport, endocytosis, exocytosis, and membrane protein pumps. During these processes, ATP is hydrolyzed to provide energy for the movement of molecules across the membrane against their concentration gradient.
Active transport... Not anything passive though.
active transport
Most of the cell's ATP is made in the inner membrane of the mitochondria through a process called oxidative phosphorylation. ATP is then stored and used as an energy source by the cell for various cellular activities.
No, facilitated diffusion does not require the use of cellular energy (ATP). It relies on membrane transport proteins to help move molecules across the cell membrane with the concentration gradient, without needing energy input from the cell.
Yes, exocytosis requires ATP. ATP is needed to provide the energy necessary for vesicle transport and fusion with the cell membrane during the process of exocytosis.
Proteins that require ATP include motor proteins involved in cellular movement, such as myosin in muscle contraction and kinesin in intracellular transport. ATP is also needed as an energy source for protein folding and unfolding processes, as well as for various cellular processes like protein synthesis and degradation.
Adenosine triphosphate (ATP) is the special molecule that provides energy for a cell's activities. It is often referred to as the "energy currency" of the cell because it stores and transfers energy for various cellular processes.
The mitochondria is the organelle responsible for synthesizing ATP through a process called cellular respiration. ATP is the main source of energy for the cell's metabolic activities.
No, osmosis is a passive process that does not require the use of cell energy (ATP). It is driven by the concentration gradient of solutes across a selectively permeable membrane.
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.
Breaking the bonds in ATP releases the energy in the bonds. Making ATP would "trap" the energy. The difference in the ion gradient across a membrane happens during cellular respiration. The enzyme ATP synthase makes ATP. It allows protons to pass through the membrane using the kinetic energy to add P to ADP making ATP. ATP production occurs in chloroplasts and mitochondria.
