Exercise $\PageIndex{1}$

What kinds of lipids are found in a eukaryotic cell membrane under normal conditions?

Here is a Hint if you need one

Answer

Glycerophospholipids, sphingolipids, sterols and fatty acids.

Date of origin

Introduction

Lipid rafts are formed and dissipated over time. They are regions where specific lipids are enriched, frequently resulting in protein aggregation as well

MODEL

No inhibition (left) and Uncompetitive Inhibition (right)

Note that the Vcell reaction diagram is the same as for competitive and uncompetive inhibition. It doesn't explicitly show that the mixed inhibitor binds to both free and substrate-bound enzymes. Those interactions are addressed in the mathematical equations for mixed inhibition.

Initial values No Inhibition

Initial values With Uncompetitive Inhibitor

I is fixed for each simulation (as it is not converted to a product) but can be changed in the simulation below.

Select Load [model name] below

Select Start to begin the simulation.

Interactive Element

Select Plot to change Y axis min/max, then Reset and Play | Select Slider to change which constants are displayed | Select About for software information.

Move the sliders to change the constants and see changes in the displayed graph in real-time.
