The transmission of a nerve message from the fingertips to the brain involves both electrical and chemical transport processes. Initially, the message is transmitted as an electrical signal called an action potential along the nerve cells through a process known as depolarization. Once the signal reaches the synaptic junction between nerve cells, it is converted into a chemical signal in the form of neurotransmitters that cross the synapse to communicate with the next nerve cell in the chain, ultimately reaching the brain.
Cellular transport processes refer to the movement of molecules across cell membranes. This includes passive processes like diffusion and facilitated diffusion, as well as active processes like active transport and endocytosis/exocytosis. These processes are crucial for maintaining cellular homeostasis and allowing cells to exchange nutrients, ions, and waste products with their environment.
Active transport processes, such as primary active transport, secondary active transport, and vesicular transport, require the cell to expend energy in the form of ATP. These processes enable the movement of molecules or ions against their concentration gradients or across membranes.
The three major processes of nutrient absorption requiring a carrier molecule for transport are facilitated diffusion, active transport, and cotransport (symport). These processes are essential for the absorption of nutrients such as glucose, amino acids, and ions in the small intestine. The carrier molecules help transport these nutrients across the cell membrane.
Two transport processes that use carrier proteins are facilitated diffusion and active transport. In facilitated diffusion, carrier proteins help move molecules across the cell membrane down their concentration gradient, while in active transport, carrier proteins help move molecules against their concentration gradient by using energy.

Vesicular transport
The two general types of transport used by cells are passive transport, which does not require energy and includes processes like diffusion and osmosis, and active transport, which requires energy and involves processes like protein pumps and vesicle transport.
passive or active transport. Passive transport does not require energy input and includes processes like diffusion and facilitated diffusion. Active transport requires energy input and includes processes like primary active transport and secondary active transport.
Active transport processes, such as primary active transport, secondary active transport, and vesicular transport, require the cell to expend energy in the form of ATP. These processes enable the movement of molecules or ions against their concentration gradients or across membranes.
