Rapidly dividing cells, such as those found in the bone marrow, gastrointestinal tract, and hair follicles, are most sensitive to ionizing radiation due to their high rate of proliferation. This is because ionizing radiation primarily affects cells during the division process, when the DNA is most vulnerable to damage.
What else can I help you with?
23) Which of the following cell types are least sensitive to ionizing radiation damage?
Mature red blood cells are least sensitive to ionizing radiation damage because they do not possess a nucleus, limiting their ability to repair DNA damage caused by radiation exposure. This makes them less vulnerable to the harmful effects of ionizing radiation compared to other cell types like stem cells or rapidly dividing cells.
What cell types are most sensitive to ionizing radiation damage?
Cells that rapidly divide are most sensitive to ionizing radiation damage, including stem cells, progenitor cells, and cells of the gastrointestinal tract, bone marrow, and skin. These cells have higher metabolic activity and are less able to repair damaged DNA compared to more differentiated cells.
How can ionizing radiation can affect living cells?
Ionizing radiation can damage living cells by directly breaking chemical bonds in DNA, leading to mutations or cell death. It can also produce free radicals that can cause additional damage to cellular components. In high doses, ionizing radiation can disrupt cell function and lead to cell death or the development of cancer.
Which of the cell types are most sensitive to radiation damage?
Rapidly dividing cells like stem cells, bone marrow cells, and intestinal cells are most sensitive to radiation damage due to their high rate of cell division, making them more susceptible to DNA damage. Cells in the skin and mucous membranes are also highly sensitive to radiation.
What is the most dangerous form of radiation and how can it be harmful to living organisms?
The most dangerous form of radiation is ionizing radiation, which includes gamma rays, X-rays, and some types of ultraviolet radiation. Ionizing radiation can be harmful to living organisms because it has enough energy to remove electrons from atoms and molecules, causing damage to cells and DNA. This can lead to mutations, cell death, and an increased risk of cancer.
23) Which of the following cell types are least sensitive to ionizing radiation damage?
Mature red blood cells are least sensitive to ionizing radiation damage because they do not possess a nucleus, limiting their ability to repair DNA damage caused by radiation exposure. This makes them less vulnerable to the harmful effects of ionizing radiation compared to other cell types like stem cells or rapidly dividing cells.
Which of the following cell types are least sensitive to ionizing radiation damage?
Red blood cells are the least sensitive to ionizing radiation damage because they lack a nucleus and are unable to repair DNA damage caused by radiation exposure. This also makes them unable to undergo cell division or replication.
Which of the following cell types are at least sensitive to ionizing radiation damage?
All of the following cell types can be sensitive to ionizing radiation damage: Stem cells: can be more sensitive because they are actively dividing. Rapidly dividing cells: such as those in the skin, digestive tract, and bone marrow. Cancer cells: due to their increased rate of cell division compared to normal cells.
Which cell type is the least sensitive to ionizing radiation?
Mature red blood cells are considered the least sensitive to ionizing radiation because they lack a nucleus and do not undergo cellular division, making them less susceptible to DNA damage caused by radiation.
What cell types are most sensitive to ionizing radiation damage?
Cells that rapidly divide are most sensitive to ionizing radiation damage, including stem cells, progenitor cells, and cells of the gastrointestinal tract, bone marrow, and skin. These cells have higher metabolic activity and are less able to repair damaged DNA compared to more differentiated cells.
Cell types are most sensitive to radiation damage?
Cells that are actively dividing are most sensitive to radiation damage.
Discuss the effects of ionizing radiation on cellular constituents?
Ionizing radiation can cause damage to cellular DNA, leading to mutations and cell death. It can also affect cell membrane integrity, disrupt cell signaling pathways, and generate reactive oxygen species. Additionally, ionizing radiation can damage cellular organelles such as mitochondria and endoplasmic reticulum, leading to impaired cellular function.
What are some examples of non ionizing radiation?
mobile/cell phones microwaves radiation and power lines
How can ionizing radiation can affect living cells?
Ionizing radiation can damage living cells by directly breaking chemical bonds in DNA, leading to mutations or cell death. It can also produce free radicals that can cause additional damage to cellular components. In high doses, ionizing radiation can disrupt cell function and lead to cell death or the development of cancer.
When ionizing radiation interacts with the suspending medium of the cell?
Indirect-hit interaction
Which of the cell types are most sensitive to radiation damage?
Rapidly dividing cells like stem cells, bone marrow cells, and intestinal cells are most sensitive to radiation damage due to their high rate of cell division, making them more susceptible to DNA damage. Cells in the skin and mucous membranes are also highly sensitive to radiation.
What is the mechanism of action of ionizing radiations?
Ionizing radiation works by delivering energy to cells, causing damage to their DNA. This can result in mutations, cell death, or impaired cell function. These effects can disrupt the ability of the cell to grow and divide, ultimately leading to the death of the affected cells.
