The carrier protein that transports hydrogen ions across thylakoid membranes and produce ATP acts as both?
The carrier protein that transports hydrogen ions across thylakoid membranes and produces ATP acts as both a pump and an enzyme. It uses the energy from the movement of hydrogen ions to generate ATP through chemiosmosis.
How do protein pumps function within cells to regulate the movement of substances across cell membranes?
Protein pumps within cells use energy to move substances across cell membranes, regulating the flow of molecules in and out of the cell. These pumps can transport specific substances against their concentration gradient, maintaining the balance of ions and molecules inside and outside the cell.
What is a carrier that transports only one type of solute at a time is called?
A carrier that transports only one type of solute at a time is called a uniporter. Uniporters are integral membrane proteins that facilitate the transport of a single type of molecule across cell membranes.
The compounds in biological membranes that form a barrier to the movement of hydrophilic materials across the membranes are?
phospholipids and cholesterol are the main compounds that form the barrier to the movement of hydrophilic materials across biological membranes. The hydrophobic tails of the phospholipids create a barrier that prevents the passage of hydrophilic substances. Cholesterol helps maintain the fluidity and stability of the membrane.
What role do membrane transport proteins, such as channels, carrier proteins, and pumps, play in the movement of substances across cell membranes?
Membrane transport proteins, like channels, carrier proteins, and pumps, help regulate the movement of substances across cell membranes. Channels allow specific molecules to pass through, carrier proteins transport molecules across the membrane, and pumps use energy to move molecules against their concentration gradient. These proteins are essential for maintaining the balance of substances inside and outside the cell.
What is passive transports function?
Passive transport refers to the movement of biochemicals and other atomic or molecular substances across cell membranes. The function of the passive transport is that it is used in filtration and osmosis processes.

What substances can pass across them but others cannot?
semi-permeable membranes
What are Passive processes that move substances across membranes?
Diffusion ,osmosis
What passive process that move substances across membranes?
Diffusion ,osmosis
What are the passive process that moves substances across membranes?
Diffusion ,osmosis
The carrier protein that transports hydrogen ions across thylakoid membranes and produce ATP acts as both?
The carrier protein that transports hydrogen ions across thylakoid membranes and produces ATP acts as both a pump and an enzyme. It uses the energy from the movement of hydrogen ions to generate ATP through chemiosmosis.
What membrane components allow movement of non-polar substances across membrane?
Integral proteins allow movement of non-polar substances across membranes.
Are membranes selectively permeable if they allow only certain substances to move across them?
False.
What is actively transported across plasma membranes?
Ions, glucose, amino acids, and certain proteins are actively transported across plasma membranes. This process requires the use of energy in the form of ATP to move substances against their concentration gradient.
When some substances can pass across them but other can not biological membranes are said to have?
selective permeability or semi-permeability
What is diffusion assisted by special protein molecules which bind to substances that diffuse across membranes?
facilitated diffusion
