Question

Difference between enzyme and homones. (At least four differences) According to class 10

Answer 1

Difference between enzyme and hormones:

Enzymes

Hormones

1. Mostly enzymes perform reactions at the place of origin i.e. in cells where they are produced. Hormones perform activity at some distance away from the site of origin.

2. Enzymes are biological catalyst. They catalyze the biological reactions. Hormones are not catalyst. They simply initiate biochemical reactions.

3. All enzymes are generally proteins. There are some exceptions like ribozymes (RNA with catalytic activity). The hormones may be polypeptides, terpenoids, steroids, phenolics compounds or amines.

4. Enzymes are not translocate from one part to another part of cell. Most of the hormones show polar translocation.

Hope it helps you ✌

Answer 2

$\huge\mathfrak\red{HELLO}$

${Here's}$${your}$ ${answer}$

1)▶Enzymes function as catalysts and accelerates the rate of biochemical reactions in the body.

Example - pepsin converts protiens to amino acids.

▶Hormone is a chemical substance secreted from an endocrine gland which is directly poured into the blood stream and acts on a target organ or cells.

Example - thyroxine

2)▶Enzymes helps in breaking down of complex food into simple forms.

▶Hormones are hereditary gene transfers.

They help in transport of genes and other chemicals

3)▶All enzymes are protein (exception is ribozyme)

▶Hormones are derivative of protein, amino acids, and steroids.

4)▶Enzymes perform their action on the site(place) where they are produced.

▶Hormones perform their action to the different place from where they are produced and are carried by the blood.

5)▶Enzymes are produced in exocrine glands.

▶ Hormones are produced in endocrine glands.

6)▶Enzymes take part in metabolism.

▶Hormones regulate the metabolic activity i.e. while giving signals to the cell for performing various body functions.
