The benefits or risks of stem cell research.
Introduction:
Stem cells are unspecialized cells that can undergo division and develop into specialized cells under the right conditions and with proper signals. These cells can specialize into various tissues, organs and organ system. They can remain in an organism for many years while undergoing cell division. There are two basic types of stem cells; embryonic stem cells and adult stem cells.
Answer to Problem 19STP
Medical researchers should be allowed to use stem cells because their research would help the doctors in curing people with many ailments. Their research work would help in tissue and organ regeneration and treatment of many diseases.
Risks- There is ethical concerns about obtaining embryonic stem cells.
Explanation of Solution
Benefits of stem cell research- Stem cells have many uses. They have the potential to cure many genetic defects and medical conditions. They have the potential to repair cardiac tissue, restore vision and treat diabetes and paralysis. Scientists are eager to do research necessary to make stem cell treatment a regular part of health care.
Stem cells can be used to treat patients with spinal cord injury. Stem cells can be extracted from many parts of the body like bone marrow, skeletal muscle cells, cardiac cells, etc. and can be manipulated to generate nerve cells. These nerve cells are then transplanted to the site of injury in spinal cord where they replace the damaged cells.
Risks- There is ethical concerns about obtaining stem cells.Some stem cell researchers have experienced roadblocks in their studies because there are ethical concerns about the source of stem cells. Obtaining embryonic stem cells is controversial as consent of donor is not taken into account but obtaining adult stem cells is not that controversial as they can be obtained with the consent of the donor.

In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardIf a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forward

Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…arrow_forward
