Enzymes:-

1.

All enzymes are proteins, except few (composed of RNA, e.g, hammerhead ribozyme)

2.

They are macromolecules with higher molecular weight

3.

They are non-diffusible through cell membrane

4.

They either act intracellularly or carried by some ducts to another site

5.

Always act as biological catalysts and increases the rate of metabolic physiological processes.

6.

They catalyze reversible or irreversible reactions.

7.

Reaction rate increases with increase in their concentration up to a limit.

8.

They act quickly



Hormones :-

1.

They may be proteins, amines or steroids

2.

They have only low molecular weight

3.

They are diffusible through cell membrane

4.

Generally carried by blood to a target organ

5.

They may be either excitatory or inhibitory in their action

6.

Hormone controlled reactions are not reversible

7.

Deficiency or overproduction of hormone causes metabolic disorders or diseases

8.

Some hormones are quick acting, while some are slow acting with a lag period.

this is above my brain level! 😥

it contains many terms which I've not listened or read ..can you please give me an answer in a simple language Accordinh to 10th standard

Could you tell me which terms you don't understand and I'll try to explain them as simply as possible.

macromolecules

excitatory, inhibitory

macromolecule is a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.

okay

Excitatory means promoting a state of excitation i.e. increased activity of anything, inhibitory is the exact opposite.

Thankyouuuu !!

enzymes are secreted by exocrine glands.hormones are secreted by endocrine glands.
