What are membrane structures that function in active transport?
Protein pumps, such as the sodium-potassium pump and the proton pump, are membrane structures that function in active transport by moving ions against their concentration gradients across the cell membrane. These pumps require energy, usually in the form of ATP, to transport substances.
What have a neutral charge proton neutron electron plasma?
neutron
What replaces the mitochondria as the site of cellular respiration in prokaryotes?
Because Prokaryotic cells contain no membrane bound organelles - the only thing they can use to create the proton concentrations needed for oxidative phosphorylation (ATP production), and photosynthesis, is the plasma membrane, which isn't as exposed in Prokaryotes as in Eukaryotic cells. Prokaryotes not only have a cell wall protecting their plasma membrane, they also have a "capsule" which provides additional support and separation for the plasma membrane, allowing it to perform this important task of creating ATP.
Why is it important that a membrane separate the cellular regions on either side of an ATP synthase molecule in order for the protein to perform its function?
A membrane separation is crucial for ATP synthase to establish a proton gradient across the membrane. This gradient serves as the driving force for ATP synthesis as protons flow through the ATP synthase from high to low concentration. Without this separation, the necessary proton gradient cannot be generated.
ATP synthase works by means of?
a proton gradient across the inner mitochondrial membrane
What is the difference between double membrane cell organelles and single membrane cell organelles?
The plasma membrane is the phospholipid bilayer that is defines the outer border of the cell. All of the organelles (which are also membrane bounds) are contained within the boundaries of the plasma membrane.
What does ATP synthase use to add phosphate to ADP?
ATP synthase uses the proton gradient created by the electron transport chain to drive the formation of ATP from ADP and inorganic phosphate. This process occurs in the inner mitochondrial membrane in eukaryotic cells and the plasma membrane in prokaryotic cells.
What is synthasizer?
ATP synthase (also known as FoF1-ATP synthase) is a multisubunit integral membrane protein that produce ATP from ADP and Pi using the energy of transmembrane electrochemical potential difference of proton (or sodium ion in some cases). The enzyme is found in bacterial plasma membrane, in thylakoid membrane (chloroplast ATP synthase) and in inner mitochondrial membrane. The main function of the enzyme is ATP production. However, in some cases (especially in bacteria) the enzyme works in the reverse direction, acting as an ATP-driven proton pump that generates the transmembrane electrochemical potential difference of proton. is it the right energy used in a body of matter from movemwent of molecules?
What is the function of the chloroplast inner membrane in photosynthesis?
The function of the chloroplast inner membrane in photosynthesis is to separate the stroma (fluid-filled space) from the thylakoid membrane system, where light-dependent reactions occur. This separation allows for the creation of a proton gradient that drives ATP synthesis during photosynthesis.
Would a proton pump require help?
No, a proton pump is a type of protein that is found in the membranes of cells and is responsible for pumping protons across the cell membrane. It does not require external help to perform its function.

Where is the electron transport chain found in a prokariotic cell?
In prokaryotic cells, the electron transport chain is located in the plasma membrane. Unlike eukaryotic cells, which have mitochondria to house this process, prokaryotes utilize their cell membrane to carry out oxidative phosphorylation and energy production. The components of the electron transport chain are embedded in the membrane, facilitating the transfer of electrons and the generation of a proton gradient.
