1. Cortisol passes through the plasma membrane into the cytoplasm. 2. Cortisol-receptor complex forms in the cytoplasm. 3. Cortisol-receptor complex enters the nucleus where it binds to genes. 4. Cortisol-receptor complex acts as a transcription factor 5. The transcribed mRNA is translated into a specific protein. Cortisol is a small, hydrophobic steroid hormone that can pass through the plasma membrane of cells. In target cells, cortisol binds to the intracellular receptor protein in the cytoplasm, forming a hormone-receptor complex. The hormone-receptor complex then moves into the nucleus and acts as a transcription factor, binding to specific genes and activating their transcription into mRNA. The mRNA that is produced is eventually translated into specific proteins. Proteins produced in response to the cortisol signal function in the stress response. For example, some of these proteins aid in elevating glucose levels in the blood, helping an animal to meet the demands of starvation or intense physical activity

About the flashcard:

This flashcard is meant to be used for studying, quizzing and learning new information. Many scouting web questions are common questions that are typically seen in the classroom, for homework or on quizzes and tests. Flashcards vary depending on the topic, questions and age group. The cards are meant to be seen as a digital flashcard as they appear double sided, or rather hide the answer giving you the opportunity to think about the question at hand and answer it in your head or on a sheet before revealing the correct answer to yourself or studying partner. Some questions will include multiple choice options to show you the options involved and other questions will just have the questions and corrects answers. Simply reveal the answer when you are ready to check your work. Absolutely no cheating is acceptable.
