Stem cells can become any type of cell in the human body, making them ideal for many types of therapies. One area of possible use is in brain cell transplants that could help people with spinal cord injuries and neurodegenerative diseases such as Parkinson's disease. Even though there is great potential for helping people, what is one ethical issue that could arise from the use of stem cells?

Answers

Answer and Explanation:

Stem cell transplant in the brain is not clinically approved yet. The only scientific and ethical via to generate a treatment is through an approved clinical essay.  Clinical investigation in the stem cell transplant involves an important and long study of the risks and benefits relationship before the treatment begins. However, the transplant is an invasive method directed to the brain that might result in very serious neurological damage, which can not be predicted by the preclinical analysis. Some of the patients treated have shown positive effects, but some others have poorly responded to the treatment. Also, some long-term studies suggest that these transplants might still result in the evolution of the disease together with secondary effects. Also, the transplant might originate cancerous cells, tumors, inadequate cell migration, immune rejection, bleeding during  surgery, and post-surgical infection. Using stem cells for clinical use requires first an ensure that the treatment will result in a long-term improvement of motor function along with a  relief of drug resistance symptoms in animals.

But the bigger problem relies on the origin of these cells. They must be obtained from embryo destruction before it reaches the uterus. This is very controversial and many people are against it due to the fact that it might involve abortion. The murder of a future person.

How is facilitated diffusion different from simple diffusion? a) facilitated diffusion requires the use of a transport protein and energy in the form of ATP b)facilitated diffusion and a simple diffusion both requires energy but facilitated diffusion uses a transport protein c)facilitated diffusion requires a transport protein d)Facilitated diffusion requires energy in the form of ATP

Answers

Answer:

a) facilitated diffusion requires the use of a transport protein and energy in the form of ATP

Explanation:

Diffusion is defined as the movement of substances from high to lower concentration across a potential gradient. Facilitated diffusion and simple diffusion are two different types of diffusion.

Simple diffusion does not require energy while facilitated diffusion requires energy in the form of ATP. Facilitated diffusion is a type of passive transport in which transport protein and energy is used in the form of ATP that allow the movement of substances across the cell membrane. There are majorly three types of proteins involved in facilitated diffusions such as channel proteins, carrier proteins, and gated channel proteins.

While in simple diffusion, pumps are used to move the substance across the membrane.

Hence, the correct answer is "a".

Answer:

a) facilitated diffusion requires the use of a transport protein and energy in the form of ATP

Explanation:

In simple diffusion, the molecules can pass only in the direction of concentration gradient. In facilitated diffusion, the molecules can pass both in direction and opposite of the concentration gradient. Simple diffusion permits the passage of only small and nonpolar molecules across the plasma membrane.
