ok i need a bit of help with my biology coursework. i was just wondering why is it that both cellulase and amylase will digest starch but amylase does it a lot quicker, any information or links would be greatly appreciated.

Sorry, I hated Chem and I doubt these will be real helpful, but I tried to find related links:

http://en.wikipedia.org/wiki/Amylose

http://en.wikipedia.org/wiki/Cellulase

http://en.wikipedia.org/wiki/Starch

Here's a link that may help. Amylase starts in the saliva gland and is more use on starch than cellulase as that seems to work better on fibre based food.

yeah they didnt really help with my question but one did explain how iodine works which was quite useful thank you

yeah that may be true but unfortunately its not detailed enough, although i could put something like that down i would need to back it up with scientific information. thanks neway

Any use?

thats looks like the criteria that the teachers are given to guide the students on what they have to do....

Cellulace breaks down cellulose to glucose. Cellulose is a structural polysaccharide that is the main material of cell walls. Cellulose and startch are both polymers of glucose, but the glucose monomers are arranged differently. Therefore, the function of Cellulace is to breakdown cellulose, not starch.

Hope that this, and my PM are helpful.

yeah i know this but i need to know why cellulase will still hydralise starch but not as fast amylase. starch is alpha glucose and cellulose is beta glucose. unfortunately with A level you must be quite detailed in your explanation. with concerns with that cambellsbiology, lets just say im glad i did not pay for it. thanks for your help anyway.

I've never used Campbells website so I wasn't sure if it was going to help or not. I couldn't give you the one's that I use because I use them, and I only have 1 key.

Can you not find more information in your book, and/or notes?

yeah that cambells place is very simple biology, unfortunately i have not found much info but i believe that it may have something to do with glycosidic bonds

Yeah that was from the first biology course that I took. But all my courses since have been neurobiology (my focus) so I'm not really familiar with the digestive system. But if you have any brain questions I can help you alot there!

What year are you?

well am lower sixth. not sure what that is american school years possibly year 12.
