Enzymes are like railway engines which take in coal, diesel, and burn the fuel and convert that into energy..
You could draw some funny picture related to words like a helix, vector, force, barrel, photon, electron, leg cell wall, membrane and then write the caption some where in a funny way..
some standard jokes on enzymes
1. Everyone knows its not the size of the vector that matters, but the way the force is delivered.
2. Hey, wanna put your alpha helix in my beta barrel?
3. You are the photon to my photosystem: you excite my electron until I reach my reaction centre.
4. If my right leg is the cell wall and my left the membrane, do you want to be the cytoplasm?
enzyme Amylase in our saliva is the one which determines what we like or donot like when we eat some thing. Perhaps, it is not completely proven. You can make use of this enzyme for a cartoon.
Your mother makes something and wants you t o eat that.. or, you left your tiffin box/lunch box intact.. When you are asked " why did you not eat that..", you could say
"well, i like that or I donot mind that... But my Amy lase (or my friend lase ) does not like it , you know... So I do not eat that... Amy means friend in some language...
