The special type of protein that accelerates the speed of reaction by existing in small amounts in various types of biochemical reactions and remains unchanged subject to certain conditions at the end of the reaction is called enzyme. Enzymes are called biocatalysts. About 4,500 types of enzymes have been discovered so far. Enzymes are known as biocatalysts, cell ferments, monocatalysts, bio-regulators, life agents etc. The study of enzymes is called Enzymology.

1. Food chain: Grasshoppers are an important food in the grassland food chain. It is the favorite food of insects, spiders, reptiles, frogs, spiders, birds etc. in the food chain.
2. As human food: Grasshopper is one of the sources of protein. It is a favorite food of the people of South America, Africa, Japan, Vietnam, Philippines etc.
3. Nutrient cycle: Grasshopper’s excrement, shell and dead body mixed with the soil play an important role in the nutrient cycle of nature. Dr. Siddiq Publications
4. As a pest: Grasshoppers swarm and cut the young tips of crops. It damages crops. Dr. Siddiq Publications
5. Parasites: Some species of grasshoppers act as secondary hosts of roundworms and flatworms.
6. Garbage eating: Grasshopper eats environmental garbage and grass leaves.

Chemical substances secreted by the body of female moths that attract male moths to mate are called pheromones. It is also called sex pheromone. For example – grasshopper, cockroach, bee, moth etc. Other pheromones are alarm pheromones, territorial pheromones, trail pheromones, releaser pheromones, primer pheromones, scent pheromones etc.

A heart in which heartbeats are generated by ganglions or nerve glands is called a neurogenic heart. For example – grasshopper, cockroach, bee, moth etc.

On both sides of the pharynx there are corpora cardiata glands. Growth hormone is secreted from this gland. Growth hormone causes the body to grow.

Ecdysone hormone is secreted from the prothoracic gland. It controls moulting. Dr. Siddiq Publications

Gonadotropic hormone is secreted from the corpora allata gland in adults. It causes penis enlargement.

Juvenile hormone is secreted from the corpora alata gland in the nymph stage. It causes growth in the nymph stage.Dr. Siddiq Publications

Prothoracicotropic hormone is secreted from the intercerebral glands of the brain. It is also called brain hormone. It stimulates the prothoracic gland to secrete hormones.

Hormones that help animals to transform their bodies are called transformation hormones.
