Stem cells are very controversial for several reasons. Mainly, because stem cells need to be harvested from Embryos, which raises a huge ethical debate as to weather the (scientifically speaking, alive) embryo harvesting is not cruel and twisted, as these are human beings that are being used. Another ethical issue is that it is related to human cloning, and often times stem cells are mislabeled. Not to mention that there is an argument for the idea of cloning humans to be used for limb replacement, throwing everybody in a tizzy. Overall, one of the greatest medical acheivements of recent years has lots of issues that haunt it.
Answer:
<u><em>Active Transport</em></u>
Explanation:
<u><em>active transport
</em></u>
During <u><em>active transport</em></u>, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
Answer:
The correct answer is - facilitated transport and secondary active transport.
Explanation:
GLUT transporter is a glucose transporter that helps in moving the glucose to its concentration gradient through the cell membrane. It is a transport protein that uses passive transport of facilitated transport that moves down their concentration gradient and therefore does not require chemical energy from ATP hydrolysis in the transport step.
Sodium-based GLUT or SGLT is also a glucose transport protein that exhibits secondary active transport as it develops electrochemical potential difference by moving ions out of the cell membrane, this gradient allows the movement of ions and molecules.
