enzymes and hormones

[victor]

i was wondering is that enzymes and hormones are made from the same basic substances which is proteine?if, it is....then why we have to differ between those two... because according to me that both of them do the same job, which is making the faster chain reactions and creating new products...

[James]

Hormones travel through the body to initiate a process, whereas enzymes are catalysts, and speed reactions up.

[mith]

Note there are 2 types of hormones, protein(peptide) based and cholesterol(steroid) based hormones. Both function as James pointed out. The only difference is duration.

Another major difference between hormones and enzymes is that enzymes act directly on the thing they are going to effect were as hormones act indirectly through cells.

For example amylase, an enzyme in saliva, directly breaks down starch to sugars.

On the other hand, Insulin (a hormone) causes cells to convert glucose to glycogen

On the other hand, Insulin (a hormone) causes cells to convert glucose to glycogen

Tecnhically, all insulin does is cause glucose to enter cells.

The form of diabetes that requires insulin is the result of the inability of glucose to enter the cells. This is why the fingertips of diabetics are often very red. The sugar accumulates and crystalizes there, causing intense joint pains.

[victor]

Insulin's work is causing glucose into cells? so, it means that glucose is bind together inside the cells become glcogen? I think that glucose is bind together inside the blood and transferred to liver....

[MrMistery]

The formation of glycogen is not that simple. Actually nothing is bio is as simple as it looks. Glicogen is formed in the liver cells as following:
Glicogenin, a protein, is the core of the molecule. It has a tirozine with a hidroxil part that attaches a glucose. An enzime catalises this reaction 8 times, then you got a liniar molecule, made up of 8 molecules of glucose-6-phosphate. Another enzime takes a piece of the liniar zone at puts it in another site. This cycle repeats a few times, and you got your molecule that contains mostly glucose-6-phosphate but also glicogenin+all the enzimes which participated at it's creation(They are not removed, they remain on the surface of the molecule)
If you understood this than you are cool!

Hey, I'll try to understand it and next time I'll explain it more clearly...ha..ha..

[Dr.Stein]

Hormones and enzymes obviously work in very different ways, victor.
In a short way I can tell you that hormones will work on cells, then they will change the behaviour of the target cells, while enzymes will work on their substrate.

[jojostar]

Can anyone give me a total of 5 similarities and differences between hormones and enzymes? please.

[victor]

I think, if you read the previous posts, you've gotten several similarities..
so, READ IT !!

A look at our dictionnary could also be a good start.
