We captured a paramecium undergoing exocytosis & expelling waste.

Endocytosis

This video was made by Biology I students in my class.

HHMI-UCI Bio 93 Exocytosis Demo

TfR-pHluorin fluorescence was imaged before and after glycine stimulation. Arrows and arrowheads indicate exocytotic events in growing and newly formed spines throughout the dendrites, respectively. The duration of glycine applied is indicated by the white circle. A pseudocolor intensity scale bar is shown. Time is indicated in min:sec. The images are 30 μm wide.

Irle Biology Project

This is a biology project that I helped film and edit. It portrays the transfer of sodium and potassium ions and ATPs in/out of the cell through endocytosis and exocytosis. Coordinator: Mum Suriyamongkol Cast: ETPS 7 Crew: Mew O.

PhD title: The role of Vitamin D in beta-cell function. Graduate student: Sue Lynn Lau Performers: Members of the Diabetes & Transcription Factors Lab Group Synopsis: Every PhD begins in the dark, but it takes only a few bright sparks to kindle the flame of discovery... The crucial role of sunlight exposure as the most important source of vitamin D in humans is highlighted. Vitamin D is newly recognised to be involved in the function of many organ systems, including the beta cells of the endocrine pancreas. These cells make insulin in response to glucose stimulation. Initially, the beta cells are in an unstimulated state, with minimal activity. At the arrival of the sugar plum fairy (symbolising glucose), the cells are able to sense the presence of glucose through the enzyme glucokinase. When glucose enters the cells through glut 2 transporters (marshmallow feeding), it is metabolised to produce the energy molecule, ATP. Through a number of steps, this leads to a rise in positive charge inside the cell, which ultimately triggers the export of insulin-storing granules by a process known as exocytosis (depicted here by the blowing of bubbles). Normal insulin secretion requires the coordinated function of beta cells via intercellular connections and communications as they work in concert. We are investigating whether vitamin D has an effect in improving beta-cell function and increasing insulin secretion... are they "walking on sunshine"??

HELLO FECES MINDS I'M BACK!!! You won't be happy about that once you see how much of a protozoan buttfuck this game is. Wait...can protozoans get buttfucked? Maybe if one of them injects their DNA into the other while they're performing exocytosis...what the fuck am I talking about!?!?

A biology project, from a year or two ago, we were assigned to teach the class a section from the book and rather than getting up and talking i decided to make this. but i gave up like half-way through
