The process that relies on a concentration gradient of protons is called oxidative phosphorylation. This process occurs in the mitochondria and involves the movement of protons across the inner mitochondrial membrane through ATP synthase, resulting in the production of ATP. The proton gradient is established through electron transport chain reactions during cellular respiration.

What is the process that allows oxygen to pass from the tracheoles to the body cells?
Oxygen diffuses from the tracheoles into the body cells through a process called passive diffusion. This process relies on a concentration gradient, where oxygen moves from an area of high concentration in the tracheoles to an area of low concentration in the body cells.
What is The process by which small molecules pass through a membrane by moving from an area of high concentration to an area of low concentration is?
This process is called passive diffusion or simple diffusion. It does not require energy input and relies on the concentration gradient to drive the movement of molecules across the membrane.
The movement of glucose molecules across a plasma membrane from an area of lower glucose concentration to an area of higher glucose concentration occurs due to?
active transport, specifically through a process known as secondary active transport or cotransport. This process relies on the use of energy generated by the concentration gradient of another molecule, usually sodium ions, to drive the movement of glucose against its gradient.
Is simple diffusion saturable?
No, simple diffusion is not saturable because it does not involve specific carrier proteins or channels that can become saturated as concentration increases. Instead, it is a passive process that relies on the concentration gradient of molecules for movement across a membrane.
What is a Small uncharged substances enter and leave the cell membrane a process of?
Small uncharged substances enter and leave the cell membrane through passive diffusion. This process relies on the concentration gradient and does not require energy input from the cell.
What name is given to the process by which substances pass into or out of a cell from an area of higher concentration to an area of lower concentration?
diffusion
Photosynthesis relies on gas defusion briefly describe the process of gas diffusion and explain what is meant by concerntration gradient?
Gas diffusion is the movement of gases from an area of high concentration to an area of low concentration to equalize the concentration of gases. This process is essential for photosynthesis as it allows for the exchange of gases such as oxygen and carbon dioxide between the plant and its environment. The concentration gradient refers to the difference in the concentration of a substance between two areas, driving the movement of the substance from an area of higher concentration to an area of lower concentration.

Why does osmosis not an active transport?
Osmosis is a passive transport process because it does not require energy to move molecules across a semipermeable membrane. It relies on the concentration gradient of solute particles to drive the movement of water molecules from an area of high concentration to an area of low concentration. In contrast, active transport requires energy in the form of ATP to move molecules against their concentration gradient.
Is energy required to move molecules from a high concentration to a low concentration?
Yes, energy is required to move molecules from a high concentration to a low concentration. This process is known as passive transport and it relies on the kinetic energy of the molecules themselves to move across the concentration gradient.
What is a Small uncharged substances enter and leave the cell membrane a process of?
Small uncharged substances enter and leave the cell membrane through passive diffusion. This process relies on the concentration gradient and does not require energy input from the cell.
Compare and contrast active transport and facilitated diffusion-?
Active transport requires energy input to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to move molecules down their concentration gradient. Both processes involve the use of proteins to transport molecules across the cell membrane, but active transport can move molecules against their concentration gradient, while facilitated diffusion can only move molecules down their concentration gradient.
What drives Facilitated diffusion?
Facilitated diffusion is driven by the concentration gradient of the molecule being transported. This means the molecule moves from an area of higher concentration to an area of lower concentration. No energy input is required for facilitated diffusion, as it relies solely on the natural tendency of molecules to move down their concentration gradient.
Is pushing a cart through a store more like an active or passive transport why?
Pushing a cart through a store is an active transport process. Active transport requires energy input to move molecules or objects against a concentration gradient, which is similar to the effort required to push a cart through a store. Passive transport, on the other hand, does not require energy and relies on diffusion down a concentration gradient.
