Proton pumps as well as ATP synthase operating in reverse maintain the hydrogen ion gradient of a cell.
ATP molecules are essentially cellular energy currency. The hydrogen gradient (or proton gradient as it is technically called) is responsible for the functioning of a protein complex called ATP synthase which in turn is responsible for the synthesis of ATP molecules. Therefore, the proton gradient is the driving force for the synthesis of ATP molecules.
The Bicoid protein gradient forms through the localization of bicoid mRNA at the anterior end of the Drosophila embryo, leading to the production of the Bicoid protein in higher concentrations in the anterior region. This gradient is essential for establishing the anterior-posterior axis of the embryo during development.
Facilitated diffusion defines he movement of materials along a concentration gradient through protein channels.

The transmembrane protein channels that are specialized for the passage of water is aquaporin's. Osmosis is the diffusion of water down its concentration gradient.

The protein responsible for producing ATP in the mitochondrial membrane is ATP synthase. This enzyme utilizes the electrochemical gradient generated by the electron transport chain to convert ADP and inorganic phosphate into ATP through a process called oxidative phosphorylation.
The pump protein helps move molecules across the cell membrane by using energy to pump them against their concentration gradient. This process is essential for maintaining the balance of substances inside and outside the cell.

Intrinsic factor or gastric intrinsic factor is a protein produced by the stomach. It is used to absorb vitamin B12 in the small intestine. When there is a deficiency of the Intrinsic factor, there is a deficiency in the absorption of B12 into the body and this leads to pernicious anemia.
Ribosomes, are responsible for protein synthesis.
