Sort the phrases into the appropriate bins depending on whether they describe exocytosis, endocytosis, or both.

a. decreases the surface area of the plasma membrane
b. requires fusion of vesicles with the plasma membrane
c. forms vesicles from inward folding of the plasma membrane
d. transported substances never physically cross the plasma membrane
e. increases the surface area of the plasma membrane
f. requires cellular energy
g. secretes large molecules out of the cell

A) Endocytosis : endocytisis is where materials are enveloped by the cell membrane to be taken in by the cell, this action will decrease the surface area while exocytosis will increase it.

B) Both : both exocytosis and endocytosis will require vesicles to fuse with the membrane.

C) Endocytosis : endocytosis will make the membrane fold inwards.

D) Both : the substances that undergo endo and exo -cytosis never physically cross the cell membrane.

E) Exocytosis : as stated in part A, exocytosis will increase the cell membrane surface area.

F) Both : both are considered active transport, meaning they will require energy in the for of ATP (adenine triphosphate).

G) Exocytosis : is when large molecules, wastes, and the likes are secreted out of the cell. Remember, Exo means out, Endo means in.

the cell cycle is the final answer! : )

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.
