ATP synthase is the protein enzyme involved in chemiosmosis. It is responsible for generating ATP by facilitating the movement of protons across the inner mitochondrial membrane.
Chemiosmosis involves the movement of ions across a membrane, which creates an electrochemical gradient that drives ATP synthesis. The membrane is necessary to separate the high and low concentration of ions, allowing for the generation of the proton gradient that powers ATP production.
ATP through the movement of protons across the inner mitochondrial membrane via ATP synthase. This process creates a proton gradient, driving the production of ATP from ADP and inorganic phosphate.
ATP formation occurs through a process called oxidative phosphorylation, where protons (H⁺ ions) move across a membrane via ATP synthase, an enzyme located in the inner mitochondrial membrane. This movement creates a proton gradient, with a higher concentration of H⁺ ions outside the mitochondrial matrix. As protons flow back into the matrix through ATP synthase, the energy released drives the phosphorylation of ADP to form ATP. This mechanism is a crucial part of cellular respiration, linking the electron transport chain to ATP production.
The universal energy molecule of the cell, adenosine triphosphate (ATP) cannot passively diffuse across the cell membranes. Despite its low molecular weight, ATP carries a strong negative charge making it hydrophilic and thus unable to diffuse across the lipophilic cellular membrane.
No, passive transport does not require ATP for the movement of molecules across the cell membrane.
The movement of hydrogen ions across a mitochondrial membrane.

The movement of protons during ATP production is called chemiosmosis. In this process, protons are pumped across a membrane, creating an electrochemical gradient that drives ATP synthesis.

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.
The universal energy molecule of the cell, adenosine triphosphate (ATP) cannot passively diffuse across the cell membranes. Despite its low molecular weight, ATP carries a strong negative charge making it hydrophilic and thus unable to diffuse across the lipophilic cellular membrane.
No, osmosis is a passive process that does not require the input of ATP. It is the movement of water molecules across a semipermeable membrane from an area of high concentration to an area of low concentration.
ATP is made in the mitochondria through a process called oxidative phosphorylation, which occurs in the inner membrane of the mitochondria. The electron transport chain generates a proton gradient across the inner membrane, which drives the production of ATP by ATP synthase.
Active transport is ATP dependent, whereas passive transport uses only the kinetic energy of the particles for movement across the plasma membrane- mastering A and P homework-
