Chart the path of molecules of a secreted protein beginning at the DNA for a eukaryote.

Nucleus :

Holds DNA and all the components of proteins.

All Eukaryotic cells have a nucleus and the rest of the membrane-bound organelles

Prokaryotic cells have no nucleus

Ribosomes :

Take the amino acids and package them into protein chains.

Ribosomes are on the outside of the endoplasmic reticulum

Endoplasmic Reticulum :

Organelle that transports the completed protein within the cell

Golgi Apparatus

Transports the completed protein from the ER to the outside of the cell.  Vesicles carrying the proteins break off the Golgi apparatus moving the proteins outside of the cell

Plasma Membrane

Selectively permeable membrane that allows passage of many materials into and out of the cell.

Transport proteins on the surface help send out messenger proteins to other cells.

Explanation:

Once proteins leave the cell they will be received by another cell.  In this way, cells are able to communicate with each other.  All cells have protein receptors on them which recognize specific proteins.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
