Biochemistry, Dopamine Receptors

Abstract

Cell-to-cell communication is critical for the survival of an organism. Cells can communicate through a process called the signal transduction pathway. When sending a signal, different molecules, such as hormones, can bind to a receptor on or inside the cell membrane, leading to chemical reactions in the cell, ultimately reaching the target. Cells use a second messenger to transmit these messages. This article will be discussing the different types of receptors, focusing specifically on dopamine receptors, the different types of dopamine receptors, and what function each receptor has. The article will also go into different illnesses and medications that target these receptors. The dopamine receptors affect many various functions, ranging from hypertension and hormonal regulation to voluntary movement and reward.

Neurotransmitters

• Acetylcholine (ACh)
• Dopamine

Stimuli

• Voluntary Movement
