Every cell in the body has a full complement of all genes, however each cell type reads only certain genes. For example, both white blood cells and liver cells have genes for making digestive enzymes but they do not read them. how is this possible??? I have no idea?
those genes are suppressed
which organs send chemicals to the small intestine to help digest food
i need help with my home work.
To understand how specific genes are expressed or suppressed in different cell types, we need to explore the concept of gene regulation. Gene regulation refers to the process by which certain genes are turned on or off in a cell, controlling the production of specific proteins.
In the human body, every cell contains the same full complement of genes, but not all genes are active or expressed in every cell type. This allows for specialization and differentiation of cells into various types, such as liver cells, white blood cells, or any other cell type that makes up different organs and tissues.
The regulation of gene expression is mainly controlled by a combination of factors including regulatory proteins, transcription factors, and epigenetic modifications. These factors determine which genes are read and translated into proteins in a specific cell type, while others are silenced or inhibited.
In the example you mentioned, both white blood cells and liver cells have genes for making digestive enzymes, but they do not read or express those genes. This is because these cell types are specialized for different functions. White blood cells are part of the immune system and are involved in defending the body against pathogens, while liver cells perform functions related to detoxification and metabolism. Hence, their gene expression profiles are different.
The specific organs that send chemicals, or substances, to the small intestine to help digest food include the liver and the pancreas. The liver produces bile, which is stored in the gallbladder and released into the small intestine to aid in the digestion and absorption of fats. The pancreas secretes enzymes that help break down carbohydrates, proteins, and fats into smaller molecules for better absorption.
I hope this helps you with your homework! If you have any more questions or need further clarification, feel free to ask.
