Electron Transport Chain
Water-soluble molecules diffuse through the cell membrane by passing through protein channels or transporters that are embedded in the membrane. These channels and transporters allow the molecules to move across the membrane, from an area of high concentration to an area of low concentration, without requiring energy.
Glucose molecules are molecules that pass through a protein instead of between the phospholipids. This is because they are to big to diffuse through phospholipids.
Facilitated diffusion occurs through a protein channel by allowing specific molecules to pass through the cell membrane with the help of a protein channel. The protein channel acts as a tunnel that facilitates the movement of molecules that are too large or polar to pass through the membrane on their own. The molecules bind to the protein channel, which changes shape to allow them to pass through, ultimately helping them move across the membrane.
Large or polar molecules, such as proteins or carbohydrates, face difficulty in passing through a cell membrane due to their size or charge.
Two characteristics that can prevent a molecule from passing through a membrane are size and charge. Larger molecules may be too big to fit through the pores in the membrane, while charged molecules may be repelled by the hydrophobic core of the membrane.
This process is known as electron transport chain. It is a series of protein complexes and molecules within the inner membrane of the mitochondria that transfer electrons and generate a proton gradient, ultimately producing ATP through oxidative phosphorylation.

The solute molecule, when passing through the membrane passively using a carrier protein, is called the substrate. The solute, or substrate will bind to the carrier protein from the outside, the carrier protein changes conformation, and the substrate is exposed to the inside of the membrane.
The series of molecules through which excited electrons are passed down a thylakoid membrane during photosynthesis is called the electron transport chain. This chain consists of various protein complexes and molecules, such as plastoquinone, cytochrome b6f complex, and plastocyanin, that work together to transfer electrons and generate a proton gradient used to produce ATP.
To determine the number of electrons passing through the bulb in one minute, we need to use the formula: Number of electrons = (current * time)/(charge of one electron) Given current = 300 A and time = 1 minute, we can calculate the number of electrons passing through the bulb. Charge of one electron is approximately 1.6 x 10^-19 Coulombs.

Integral protein channels facilitate the movement of ions and small molecules across cell membranes. These channels are selective based on the size and charge of the molecules they allow to pass through.
