it says that the cornea has unmylenated nerve endings.. and that The cornea is very sensitive to pain because of the ciliary nerves that run just underneath the endothelium.
... does that mean that it's made of nerve cells or that it just have nerves that run through it??

What would happen to an enzyme-facilitated reaction if temperature were increased. What would be the effect if temperature were increased to 100 degrees Celsius?

What is the optimal temperature (degrees C) for enzymes functioning in the human body?

How does a competitive inhibitor affect the rate of an enzyme-mediated chemical reaction?


Really stuck on these questions. :/ Any help is appreciated.

I posted a question in the religious section about why Christians are allowed to sit out of the section on evolution in my 10th grade biology class when it's accepted science, and a lot of people said it's not.

I thought it was, and it's just the Christians who don't believe it. Are there non-Christians who don't believe in evolution? Is it widely accepted as sceince?

So i need it by tomorrow, and i already got 13 of them. just 2 more left... they are:
1. cytoplasm/cytosol
2. chloroplast/plastid
i need to relate them with an amusement park w/ reasons why it is. For example:

A mitochondria is to a cell just as the vending machine is to an amusement park. Just as the mitochondria provides ATP by using sugar, fat, & oxygen to power the cell. The vending machine uses food to power the employees to work at the amusement park.

I'm looking at the protein bovine rhodopsin.

I'm suppose to find out how far the closest disulfide bond is from the methionine end of the protein.

Currently i'm using .... i'm not sure what the site is actually called, but if you google genbank its the first hit.

Using the CN3D program. It shows me 3d view of the molecule and then spits out the amino acid sequence.

Is there a way i can look at the sequence to figure out where this bond is?

Err...do i look for the closest cystein...and assume thats where the disulfide bond occurs...with another cystein.. I'm a chemical engineer not biochemist....i think i learned somewhere years ago that cysteins form the bonds.....but i'm having no luck googling that.

Red blood cells contain no DNA. During differentiation that right was given up in order to be able to carry oxygen and sustain hemoglobin. Then how is it possible to use someone's blood to identify them? Blood type is not enough to identify a person.

I know you're a very busy Professor, but I would greatly appreciate the professional help for my midterm ( university of course) I totally understand if you don't have the time. Thanks

And for others that can explain this to me.. Very welcome.. Thank you to all.

Why does the cell have checkpoints in the cell cycle? Name one. ( this one is quite important.. i dont really understand how the cell cycle does.. like why is it soo important...)

Why do many molecules not break down rapidly into smaller molecules, even when it is energetically favorable?

Where do competitive inhibitors of enzymes bind?

Why would a cell prefer respiration over fermentation?

What is alternative splicing?
