Which of these statements is true regarding receptors for peptide or amine hormones?
a. If bound to the hormones themselves, receptors for peptide or amine hormones can act as transcription factors.
b. Receptors for peptide or amine hormones are typically located in the plasma membrane of cells.
c. Receptors for peptide or amine hormones are typically located in the cytoplasm of cells.
d. Peptide and amine hormones do not require receptors, as these hormones can diffuse directly across the plasma membrane of a cell.

Explanation:

1. Receptors for peptide or amine hormones located on the plasma membrane of cells, whereas receptors for lipid-soluble hormones are usually found within or inside  the cytoplasm because lipid-soluble hormones can easily cross the cytoplasm.

2. After binding hormone,  there is the change in the receptor and the receptor can initiate multiple signaling pathways.

3. These pathways finally causes the changes in the behavior of the target cells.

4. There are various type of hormones, some of them are excitatory and some are inhibitory.

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.
